Piriform Fossa and Nasolabial Fold Filler: Mapping the Angular and Facial Arteries on Ultrasound, Plus the 6 Best Scanners (2026)

Quick answer: which ultrasound should you buy for piriform fossa and nasolabial fold filler?

Piriform fossa and nasolabial fold scanners compared: six handhelds side by side

Side by side, the six ranked scanners split on four things the fold and the fossa demand: a top frequency at or above the 15 MHz facial floor, Doppler that tells a 1.4 mm angular artery from its vein, a needle or cannula view in the plane, and what the software behind each scored tool costs over five years.

Six scanners for piriform fossa and nasolabial fold filler, ranked; prices and plans checked October 31, 2026; the lifetime FaceAtlas AI license is sold until 11:59 PM PT, December 31, 2026.

Why map the nasolabial fold and the piriform fossa before filler?

Mapping the fold and the fossa before filler matters because the nasolabial fold is the third most frequent site in the published reports of skin necrosis and vision loss after filler: of 164 cases gathered from 45 articles, 44.5% followed injection of the nose, 21% the glabella, 15% the nasolabial fold and 10% the forehead (Rauso 2020). Occlusion signs and the steps that follow one are set out in the guida all'occlusione vascolare. The map comes before any of that: the facial and angular arteries located at the exact points you plan to inject, on each side.

The 2025 international Delphi consensus on ultrasound in aesthetic injectables lists the pyriform fossa among the five areas where vascular mapping is mandatory, with the forehead, glabella, temple and nose, and recommends mapping for the lips, lower eyelids, zygomatic arch, chin and pre-auricular region. The same panel recommends ultrasound-guided injection in the pyriform fossa, a linear probe of at least 15 MHz and a check for earlier filler before new product goes in, and makes image archiving mandatory (Velthuis 2025). Gonzalez 2026 recommends imaging for the forehead, glabella, nose and pyriform fossa. The map earns its place quickly: across 503 patients mapped before HA filler, an artery wider than 0.8 mm lay under 43 of 324 planned nasolabial fold sites, 13.2%, and each map took under 3 minutes (Teixeira 2025).

Nasolabial fold anatomy and the facial artery course from the jaw to the ala

Nasolabial fold anatomy, read from the surface down, is skin, a subdermal fascial-fatty layer that runs from the upper lip across the fold into the cheek mass (Yousif 1994), mimetic muscle fibers that send dermal extensions into the crease (Barton 1997) and fat compartments that behave differently on each side of it, with the facial artery threading through these layers at a depth that changes from the jaw to the ala. In the upper lip the SMAS is the superficial part of the orbicularis oris (Yousif 1994). The skin at the fold measures 1.601 ± 0.617 mm on high-frequency ultrasound, the epidermis 0.325 mm and the dermis 1.276 mm, the thinnest epidermis of the eight facial sites measured in 99 adults with an L18-5 linear at a 15 mm image depth (Jeong 2023). Under the skin the fold scans as a hypoechoic subcutis over the levator labii superioris alaeque nasi and the levator anguli oris, both hypoechoic too (Vasconcelos-Berg 2024).

The fat beside the fold sits in separate compartments. The nasolabial fat is a compartment of its own with fixed boundaries (Rohrich 2007); deeper in the cheek, the deep medial cheek fat has a medial part against the pyriform membrane and a lateral part on the maxilla, and its volume loss deepens the fold (Rohrich 2008). Product follows the compartment it lands in. In the superficial nasolabial compartment it moves downward as the volume grows (rp = 0.92, p = 0.003; Schenck 2018), while the deep pyriform space, the deep medial cheek fat and the deep nasolabial compartment inside the premaxillary space take volume with no inferior displacement, and deep filler on the bone projects the tissue forward (40 specimens; Cotofana 2019). Hong 2024 sorts folds into three types: a paranasal depression (type 1), a sagging nasolabial fat pad (type 2) and a crease pulled by the lip elevators (type 3), with fibers of the levator labii superioris alaeque nasi, the levator labii superioris and the zygomaticus inserting into the skin beside the nose. With age the pyriform aperture widens from young to middle age in both sexes (Shaw 2007), and the maxilla resorbs, the lower pyriform rim most of all (Mendelson 2012).

The facial artery course along the fold falls into four types in a Doppler meta-analysis of 610 arteries: medial to the fold (type A) in 46.2%, crossing it from medial to lateral (type C) in 22.5%, crossing from lateral to medial (type D) in 18.5% and lateral to it (type B) in 12.0% (Pourani 2025). Type A is the most symmetric between the two sides and type D the most asymmetric, and type B turns up about twice as often in a cadaver series as on Doppler, 23.2% against 12.0% (Yang 2014; Pourani 2025). Single series swing around the pooled shares: color Doppler of 376 arteries in 188 patients found type A in 55.7%, with the course asymmetric between sides in most patients and more often in women, 54.3% (Boz 2024), and ultrasound typing of 45 patients found individual variation in the course in 38% (Hong 2026). Map each side on its own.

The layer changes too. In 80 Doppler-mapped folds the artery ran lateral to the fold in 31%; where it passed under the fold it lay subdermal in 13%, subcutaneous in 29%, within the muscle in 24% and submuscular in 4%, and the filler went into whichever layer bypassed it (Lee W 2021). In 60 specimens from 36 cadavers the artery sat 3.2 ± 4.5 mm lateral to the ala and 13.5 ± 5.4 mm lateral to the commissure, crossed the fold in 33.9%, came within 5 mm of it in 42.9% and sent detoured branches in 30.0% (Yang 2014). CT angiography of 255 arteries put it medial to the fold in 65.5% and fully lateral in 12.3% (Koziej 2019), and in 52 cadavers it continued as the angular artery in 83.7% (Peng 2024).

Read together, the depths set the scan window. The pooled Doppler means sit 6 to 8 mm down, in the lower half of a 10 mm image, yet single faces range from 2.5 mm at the jaw to 23.5 mm beside the ala, and the authors of that 168-hemiface series conclude that no depth and no region of the fold is absolutely safe (Ten 2021). The caliber narrows from 2.14 mm at the jaw to 1.46 mm at the ala, and Doppler found the artery at 100%, 99.9% and 99.8% of the three levels (Pourani 2025). At 22–8 MHz its cross-section shrank from 2.2 mm² at the mandible to 1.1–1.2 mm² at the alar base, and on the left side it showed at the cheilion in 39 of 41 volunteers and at the alar base in 37 of 41 (Pistoia 2023). The whole-face artery depths, temple to chin, are in the guida dedicata alle iniezioni di filler ecoguidate.

At the commissure the facial artery gives off the superior labial artery, and the lip carries its own arteries, depths and injection points, all in the guida alla tecnica del filler labiale. Upward from the mouth corner, the facial artery ends as the angular artery in 71.8% of 234 arteries and as the lateral nasal artery in 27.9% (Pourani 2025).

The angular artery over the deep pyriform space

The angular artery runs in the roof of the deep pyriform space, inside the septum between the space and the deep medial cheek fat, above the bone where pyriform filler is placed (Surek 2016). In 12 cadaver hemifaces the space averaged 1.1 × 0.9 cm: the depressor septi nasi bounds it medially, the deep medial cheek fat and the lip elevators cradle it laterally and superficially in a half-moon, and it extends upward to the level of the tear trough ligament in a plane deep to the premaxillary space. On 20 MHz Doppler in 166 volunteers the angular artery lay 3.6 ± 1.7 mm under the skin and 5.1 ± 2.9 mm above the bone, with the supraperiosteal plane 9.11 ± 2.4 mm from the skin, and it was found in the space in 94.9% of 332 hemifaces (Franceschelli 2024). That study scanned patients semi-seated, with the probe vertical at the angle between the ala and the cheek, on thick gel without touching the skin.

Within 3 mm of the bone in 38.6% of hemifaces, the artery sits where a supraperiosteal deposit would meet it, and the same authors keep boluses and supraperiosteal injections out of those hemifaces and count a negative aspiration as no test of safety (Franceschelli 2024). A second Doppler series in 58 adults, 116 sides, measured the artery on a 4–16 MHz linear with a surface preset: B-mode at 10–13.5 MHz, Doppler at 5.0 MHz, PRF 0.5–0.8 kHz, a 30 mm depth and 300 frames per second, the probe longitudinal between the ala and the anterior maxilla with its marker perpendicular to the ala, the patient supine, generous gel and no compression (Bustamante 2025). The artery measured 1.4 mm across in women and men alike, losing 0.01 mm per year of age; it lay 4.8 ± 1.6 mm under the skin in women and 5.8 ± 1.7 mm in men, 3.9 and 4.2 mm above the bone, with the bone 10.1 and 11.4 mm down. A pulsatile spectral trace, peaking at 21.1 cm/s in women and 19.2 cm/s in men with a resistive index of 0.9, told it from the angular vein; each examination took about 15 minutes, and the two examiners agreed at an ICC of 0.891 to 0.967.

The angular artery takes four forms in 57 cadaver hemifaces: a persistent pattern along the side of the nose (11%), a detouring pattern across the cheek and tear trough (18%), an alternative pattern reaching the medial canthus through a branch of the ophthalmic artery (22.8%) and a latent pattern with the angular artery absent (26.3%) (Kim 2014). On 18 MHz color Doppler in 43 people the angular artery was absent in 11.62% (Khorasanizadeh 2023). Over the frontal process of the maxilla, lateral to the pyriform aperture, a 5–12 MHz study measured the angular artery at 1.39 mm across, with a peak systolic velocity of 20.73 cm/s and a resistive index of 0.65 (Tucunduva 2016). At the ala, CT of 156 faces placed the main arterial trunk 13.7 ± 3.7 mm deep and under the levator labii superioris alaeque nasi in 53.6% (Gombolevskiy 2021).

Medial to the deep pyriform space lies the perialar space, dissected in 44 cadaver hemifaces: the levator labii superioris forms its lateral wall, the alar fibrofatty tissue its medial wall and the transverse nasalis its roof (Yoon 2026). Yoon’s puncture sits 1 cm along a perpendicular from the midpoint of the fold; a 21G needle opens the track and a 23G 50 mm cannula fills the space with 0.5 to 1 cc per space. Beside it, the premaxillary space is semi-open between bony and muscular borders, and 0.5 to 0.8 mL placed there improved the nasolabial groove in Thiel-embalmed cadavers (Pilsl 2014).

Piriform fossa filler: the injection point, the plane on bone and the volumes

Piriform fossa filler goes on the bone 0.3 to 0.5 cm lateral to the ala: scan the point with Doppler first, move it until no artery sits under the needle, then pass a 27G needle at 90 degrees to the periosteum, aspirate and inject slowly into the supraperiosteal plane (Vasconcelos-Berg 2024). The same guide uses this needle technique for severe volume loss in the fossa. The bony landmark gives the area its second spelling, so pyriform fossa filler and the piriform spelling name one treatment at one site: the paranasal hollow over the pyriform aperture beside the ala. The map comes first because the angular artery runs 3.6 mm under the skin there and lies 1 mm or less from the bone in 2.4% of hemifaces and practically on it, at 0.1 mm, in another 0.6%, right where the needle tip stops (Franceschelli 2024).

Layering treats the rest of the fold from one entry. Jung 2020 worked through the triangle between the alar base and the commissure in 20 patients with no complications: a 25G puncture at the commissure, then a blunt cannula threaded retrograde into the deep pyriform space on the periosteum, next the supraperiosteal and deep fat planes with linear threads and fans, and last the superficial fat and the subdermal plane, at 0.03 to 0.05 mL per thread and 1.0 to 1.5 mL per side, with 2 units of toxin per side to the levator labii superioris alaeque nasi when that muscle pulls hard. The deep compartments hold their place as volume rises (Cotofana 2019) and the superficial nasolabial compartment slides downward (Schenck 2018); Hong 2026 layered in the same order, deep first and superficial second, under real-time ultrasound. Peng 2024 recommends supraperiosteal injection in the upper third of the fold and the dermal layer in the lower two thirds, Lee W 2023 puts high-G′ HA on the periosteum once the map is done, and Ramos 2025 pairs HA in an empty deep pyriform space with abobotulinumtoxinA in the nasal muscles.

Nasolabial fold injection: filler technique by product, point and plane

In the nasolabial fold filler technique, a nasolabial fold injection places the product at up to three points per side, NL1 to NL3 in the MD Codes protocol, in the plane that its US label and the point call for, by needle or cannula, after Doppler has mapped the facial and angular arteries at each point. Each filler below was approved by the FDA through premarket approval (PMA) for moderate to severe facial wrinkles and folds such as the nasolabial folds. For the fold itself these labels run from the mid dermis to the superficial subcutis, and the supraperiosteal plane appears in Restylane Lyft’s cheek indication.

MD Codes set three points per side along the fold: NL1 at the upper fold beside the nasal flare, where the protocol flags the facial artery and its branches to the flare, NL2 at the center and NL3 at the lower fold (de Maio 2021). For bone deficiency at the upper fold it places 0.3 mL per side on the bone at NL1 with a needle, aspirating on the bone. Mild to moderate folds take 0.3 mL at NL1 and 0.2 mL at NL2 in the subcutaneous plane by cannula; severe folds take 0.5, 0.3 and 0.2 mL at NL1, NL2 and NL3, 1.0 mL per side. The cannula serves dynamic folds and a deep-dermal needle serves fine lines, with the volumes drawn from Vycross products.

The cannula route for the fold enters 1 to 1.5 cm lateral to the commissure along the natural wrinkle line, uses a blunt cannula of 25G or larger in the subcutaneous plane and runs retrograde from the nasal end to the labial end, with the probe laid along the cannula in-plane and scanning while the product goes in (Vasconcelos-Berg 2024). The artery averages 13.5 ± 5.4 mm lateral to the commissure in cadavers (Yang 2014), right beside that entry, so the map at the entry and along the track comes before the puncture. In Lee W 2026 a finger-held 15 MHz probe ran Doppler through each cannula injection from an entry lateral to the fold: the artery lay in the subcutaneous fat above the fold, the left side took a mean of 0.98 mL (0.5–2 mL) and the right 0.95 mL (0.5–1.5 mL), and none of the 33 patients had a vascular complication.

Gauge, entry and tool choice for each point are compared in needle or cannula for the fold and the fossa.

Radiesse, a calcium hydroxylapatite filler, holds its own nasolabial fold indication under FDA premarket approval P050052 of December 22, 2006, for subdermal implantation with a 25G to 27G needle.

Map, inject, rescan: the ultrasound workflow for the fold and the fossa

The ultrasound workflow for the fold and the fossa runs in five steps, map, plan, inject under guidance, confirm and rescan, built on Rocha’s three-step Doppler method of arterial mapping, real-time guided filling and a perfusion check, used in 480 patients at 18 MHz (Rocha 2022). Teixeira 2025 times the method’s guided filling at 5 to 20 minutes and its perfusion check at 1 to 3 minutes, and the arterial map alone at 1 to 3 minutes in a series of 503 patients.

1. Map and mark, face at rest. Scan with the face relaxed: a smile pressed the angular vein against the maxilla and cut its flow from 6.12 to 0.52 cm/s, to zero in 80.8% of observations after 3 seconds (Cotofana 2020). Scan each side separately, hold the probe perpendicular to the vessel, mark its cross-section on the skin point by point and join the points into a line (Sigrist 2024). Look for earlier filler before any new product goes in (Velthuis 2025).
2. Plan the plane at each point. Where the artery passes under the fold, pick the layer that bypasses it, as Lee W 2021 did in 80 folds. Where it runs within 3 mm of the bone at the fossa, keep the deposit off the bone at that point (Franceschelli 2024). The labels hold the fold’s product in the dermis or the superficial subcutis, and MD Codes put NL1 on the bone for bone deficiency (de Maio 2021).
3. Inietti sotto guida ecografica. At the fold, lay the probe along the cannula and scan while injecting, confirming the tip in its layer and clear of the facial artery and vein branches; at the fossa, clear the point on Doppler, then set the 27G needle on the bone at 90 degrees (Vasconcelos-Berg 2024). Lee W 2026 kept a finger-held 15 MHz probe on Doppler through every cannula pass.

4. Confirm the placement. Under ultrasound, cannula filler held its intended plane in about 90% of 100 injections at day 0, day 14 and day 30, while the product area went from 22.51 to 12.9 mm² (Calomeni 2023). Layering the volume-deficient folds of 20 patients deep then superficial with real-time depth confirmation, Hong 2026 reported no vascular compromise or malposition, a median GAIS of 2 at 12 weeks and rescans showing even spread in the target planes.
5. Ripeta la scansione. Bring the probe back after each pass to confirm the cannula sits outside the vessels and in the planned plane (Sigrist 2024), then close with the perfusion check of Rocha’s third step (Rocha 2022).

Fresh hyaluronic acid has a recognizable look at each frequency. At 70 MHz, HA in the fold showed as several anechoic oval areas in the dermis, which thickened from 2.04 to 2.28 mm, 11%, and still measured 2.19 mm at 24 weeks (Salvia 2023). At 20 MHz it formed well-demarcated hypoechoic or anechoic areas in the subcutis, one product spreading as many small bubbles and the other as larger clumps (Qiao 2019). At 15 MHz it read anechoic, with a distinct boundary, good through-transmission and no flow (Jiang 2022, as summarized in Salvia 2023). Earlier filler belongs on the pre-map as well: in 94 patients scanned at the nasolabial groove the material was HA in 35, polyacrylamide in 34, fat in 10, silicone oil in 7, calcium hydroxylapatite in 6 and a silicone implant in 2, told apart by echo intensity, texture, boundary, fluidity and flow (Jiang 2022), and a blinded sonographer found the filler at the injection site in all 36 subjects after lip or fold filler (Grippaudo 2010). HA sitting where new product is planned can be dissolved first, as set out in the guide to dissolving HA filler under ultrasound.

FaceAtlas AI turns the map into a record on all six Suresult linears. Color Power Doppler (CPD) shows blood-flow signals on the live scan before the needle goes in; a freeze gives skin thickness, subcutaneous fat thickness and depth to the SMAS in millimeters, and a 5-second clip keeps the motion. Filler Scan names the material already in the tissue and measures its depth and size, for example HA at 2.6 mm deep over 20.7 mm², across seven materials: HA, collagen, PLLA, PCL, CaHA, PMMA and PVA, and the filler assessment adds abnormality screening and complication evaluation. The 21-point map runs from forehead to jawline with two nasolabial fold points and two perioral points, one of each per side, so every follow-up rescans the same spot. Dual View sets the raw scan beside the AI layers while the filler goes in, one click puts this visit beside the last, and each visit exports as a US Letter PDF.

Doppler settings for the facial and angular arteries

Small facial arteries need slow-flow settings: a velocity scale near 3 cm/s with the PRF and the wall filter brought down to match, plenty of gel and almost no probe pressure (Sigrist 2026). Conventional wall filters hide slow flow in small vessels (Pistoia 2023), which is why the filter comes down with the scale. The table gives each step for the fold and the fossa; what each Doppler mode shows is explained in the portable Doppler ultrasound guide.

Every Suresult linear carries these controls on its own Doppler: PRF, wall filter, steer, color gain and Move & Zoom in Color and PDI, and PW gain, steer, sample volume and angle in PW, with peak systolic velocity, end-diastolic velocity, resistive index and vessel diameter measured on the trace. For coupling, the Cuscinetti in gel per ecografia estetica Suresult are clear, sterile hydrogel pads of Ø35 × 4 mm, each in its own sealed pack, latex-free and ISO 10993 biocompatibility-tested, with a 5-year shelf life. One pad stays on from the Doppler map to the last pass, the needle goes straight through it, it repositions on the skin, and it fits all six Suresult linears and other brands’ linear probes, at $140 for 50 with shipping and tax included. The 4 mm stand-off uses 4 mm of display depth, so the L20Pro’s 10 mm preset shows about 6 mm of tissue under a pad. Sterile coupling for the in-plane probe is set out in the sterile coupling section of the filler injections guide.

What frequency and depth the fold and the fossa need

The fold and the fossa need a linear probe of at least 15 MHz, the floor in the 2025 Delphi consensus and in the WFUMB position paper, which puts axial resolution at 100 µm at 15 MHz (Velthuis 2025; Chammas 2025). Above the floor, frequency trades depth for detail: 20 MHz reaches about 10 mm and 10 MHz about 35 mm (Mlosek 2020), 18–22 MHz shows vessels of about 0.1 mm (Jaguś 2020), and Veronese 2024 names 24 MHz the method of choice for reading the facial dermis and hypodermis in vivo. The table matches each target to the band and the preset that hold it, using the deepest reading of each target as its limit.

That makes the L20Pro the one probe for the whole fold: 20 MHz at 10 mm for the dermis and both arteries, and 16 MHz from 20 to 40 mm for the bone, the deepest arterial course and the deep cheek, with Color, Power and PW Doppler, Needle Enhance, in-plane and out-of-plane guides and a 25 mm field. The L24Pro adds the finest near field in the line, 24 MHz on 256 elements, for the dermis over the fold and the angular artery at 3.6 mm, and images to 25 mm. The L14Pro and L14 run at 10/14 MHz with presets to 80 mm for body work; for the fold and the fossa, the 15 MHz floor points to the 16/20 and 18/24 MHz bands. The 15, 20 and 24 MHz trade-offs are compared in the guida agli ecografi ad alta frequenza, and the three Suresult linear bands head to head in L14 vs L20 vs L24 for aesthetic ultrasound.

The 6 best scanners for piriform fossa and nasolabial fold filler, ranked

For piriform fossa and nasolabial fold filler the Suresult L20Pro ranks first at 95.0/100, ahead of the Clarius L20 HD3 at 75.0, the Mindray TE Air e5M at 58.5, the GE Vscan Air SL at 48.4, the Butterfly iQ3 at 45.7 and the Philips Lumify L12-4 at 43.6. I scored each card on the seven criteria set out under How I scored, with the rival prices read on October 31, 2026.

01 Suresult L20Pro — Best Overall for Piriform Fossa and Nasolabial Fold Filler

16/20 MHz linear on 256 elements · 10/20/30/40 mm presets · Color, Power and PW Doppler in the price · Needle Enhance plus in-plane and out-of-plane guides · $3,720

Punteggio: 95,0/100

4,400 mAh, up to 4 hours a charge · 145 g · IP67, drop-tested · no subscription for imaging or Doppler · $3,720

See the Suresult L20Pro high-frequency probe: $3,720

Verdetto: Buy the L20Pro if you fill both the fold and the fossa. I rank it first because one probe maps the angular artery and the facial artery along the whole fold at 20 MHz, switches to 16 MHz for the bone under the deep pyriform space, carries all three Doppler modes and Needle Enhance in its price, and keeps each map for the rescan.

• Both arteries: 20 MHz on the 10 mm preset holds the angular artery at 3.6 mm and the facial artery’s pooled mean depths of 6.27 to 8.04 mm; a PW trace tells the 1.4 mm angular artery from its vein
• Depth range: 16 MHz on the 20, 30 and 40 mm presets reaches the bone at 9.11 to 11.4 mm, the facial artery’s deepest course at 23.5 mm and the deep cheek
• Needle and cannula: Needle Enhance, Flip, Grid and the in-plane and out-of-plane puncture guides across a 25 mm linear face
• Documentazione: cine of up to 1,000 frames, about 165 seconds; local storage; JPEG, PNG, MP4 and DICOM export; apps for iOS, Android and Windows
• Mapping software: FaceAtlas AI carries two nasolabial fold points and two perioral points in its 21-point map, reads skin, fat and SMAS depth in millimeters, shows blood flow on Color Power Doppler before the needle goes in, and names HA among seven filler materials with its depth and area
  

  

• FaceAtlas AI license: the L14Pro, L20Pro and L24Pro each include 3 months, counted from the day you press Start; the L14, L20 and L24 run it on a key at $50 per month, $500 per year or $999 for the life of the device, and the lifetime key is sold until 11:59 PM PT, December 31, 2026

Perché occupa questa posizione. The L20Pro takes the maximum on six of the seven criteria: 20 MHz for resolution, the 40 mm preset for depth, all three Doppler modes in the purchase, FaceAtlas AI mapping in the 3 included months, Needle Enhance with the guides, and 1,000 frames of cine with DICOM. Its five-year total, $4,719 with the lifetime key, sold until 11:59 PM PT, December 31, 2026, scores 9.975 of 15 against the lowest total I scored, the Suresult L14 at $3,138.

Sub-scores: resolution 20/20, depth 10/10, Doppler 25/25, mapping software 15/15, needle and cannula 10/10, records 5/5, five-year cost 9.975/15.

The L20Pro and its five Suresult siblings are la clearance 510(k) K211321.

L20Pro, L24Pro o L14Pro? All three Pros run on 256 elements with Color, Power and PW Doppler, Needle Enhance, a 4-hour battery and 3 months of FaceAtlas AI, so the band decides. The L20Pro covers the fold and the fossa from the dermis to the bone. The Suresult L24Pro handheld ultrasound ($4,185) adds 24 MHz, the finest near field in the line, for the 1.3 mm dermis over the fold and the angular artery at 3.6 mm, with presets to 25 mm. The Sonda lineare Suresult L14Pro ($3,441) runs 10/14 MHz to 80 mm for the body, and the 15 MHz Delphi minimum hands the face to the other two.

Ideale per: injectors who map the facial and angular arteries, fill the fold and the fossa and rescan on one probe from the dermis to the bone. Scelga un modello della famiglia se: you want the 24 MHz near field on 192 elements at $3,441 (the L24), or the 16/20 MHz band at $3,000 with FaceAtlas AI on a key (the L20). Confronti con attenzione se: you want a preset named Pyriform and an on-screen depth of the shallowest vessel on a membership (the Clarius L20 HD3).

03 Mindray TE Air e5M — Best for Color, Power and PW Doppler at the Lowest Five-Year Rival Cost

2-in-1 convex and linear transducer · linear B-mode bands to 8.2 MHz in a 2.0–9.0 MHz bandwidth · images to 40 cm · Color, Power and PW Doppler standard · iNeedle and VA Grid · $4,499

Score: 58.5/100

229 g · 90 to 120 minutes of B-mode scanning · IP68 · 3-year warranty · $4,499

Verdetto: Buy the TE Air e5M if you want Color, Power and PW Doppler, a needle-enhancement mode and a vascular access grid in one purchase with nothing to renew, on a 2-in-1 transducer that adds a convex mode for whole-body imaging. Its linear B-mode bands top out at 8.2 MHz, under the 15 MHz minimum the 2025 Delphi panel sets for facial injectables.

• Doppler: Color, Power and PW standard, Color and PW at 4.0, 4.4 and 5.0 MHz on the linear; Color to 146 cm/s, Power on 30 scale levels, a PW scale from 1.0 cm/s and a 0.5–20 mm sample volume
• Strumenti per l’ago: iNeedle needle-visualization enhancement, left or right, and the VA Grid for vascular access, both specific to the e5M

• Documentazione: cine up to 125 frames, preset from 2 to 5 seconds; JPG and MP4 export; DICOM 3.0; patient data kept on board, with no cloud and no subscription
• Prezzo e clearance: $4,499 at the Mindray North America store, checked October 31, 2026, with no subscription plan; the Air Capsule for wireless charging costs $750; the FDA cleared the e5M transducer with iNeedle, Smart Calc, iWorks and iScanHelper under 510(k) K240906 on July 23, 2024

Perché occupa questa posizione. All three Doppler modes in the purchase take the full 25 points, iNeedle with the VA Grid the full needle credit, DICOM with onboard storage 3 records points, and $4,499, the lowest five-year total among the rivals, 10.462 of 15. The resolution rule starts counting at 10 MHz, so linear bands that end at 8.2 MHz score 0, and Smart Calc measures vessel diameter and area, which the software criterion does not credit.

Sub-scores: resolution 0/20, depth 10/10, Doppler 25/25, mapping software 0/15, needle and cannula 10/10, records 3/5, five-year cost 10.462/15.

Limiti. The linear B-mode bands run from 2.0 to 8.2 MHz, under the 15 MHz floor for facial work; cine holds 2 to 5 seconds; Mindray names no layer-depth, injection-point or filler-material tool.

Ideale per: whole-body practices that want all three Doppler modes and the needle tools paid once, with no plan to renew. Scelga altro se: you image the dermis over the fold or the 3.6 mm angular artery at 15 MHz or more, or want layer depths and filler mapping in the software.

Come ho assegnato i punteggi

I scored each card out of 100 on seven criteria and weights fixed on October 31, 2026, before any rival had a score:

• Resolution (20): 20 × (top frequency in MHz − 10) ÷ 10, kept between 0 and 20, so 20 MHz and up earns 20, 15 MHz 10, 12 MHz 4 and 10 MHz or less 0.
• Depth (10): 10 × the deepest preset or image depth in mm ÷ 30, counted up to 30 mm, the plane that reaches the pyriform bone with room to spare.
• Doppler (25): Color 9, Power 8 and PW 8, each at full value when the purchase includes it, half when a paid tier unlocks it and zero when it is missing.
• Filler-mapping and safety software (15): filler materials named on the scan 5, a vessel or injection-point map 5 and layer depth in mm 5. Each counts in full when the purchase includes it, half when a paid tier or key unlocks it and zero when it is missing. FaceAtlas AI counts as included on the L14Pro, L20Pro and L24Pro, sold with 3 months of it, and as a paid tool on the L14, L20 and L24, where the key is bought separately; any tool its maker sells without a named tier counts as included.
• Needle and cannula guidance (10): 5 for needle enhancement and 5 for in-plane or out-of-plane guides, biplane views, or a centerline, midline or access-grid aid named for needle work, halved when the tool sits in a paid tier.
• Records (5): 2 for cine of 60 seconds or more and 3 for storage with DICOM export.
• Five-year cost (15): 15 × the cheapest five-year total of the 12 models I scored, divided by this card’s total. A Suresult total is the October 31, 2026 hardware price plus one lifetime FaceAtlas AI key (sold until 11:59 PM PT, December 31, 2026), and the L20’s uses the $3,000 printed on its page; the Clarius total carries one-time Essentials, the Butterfly total five years of Advanced, and the L14’s $3,138 is the cheapest and sets the scale.

Siblings are scored inside their maker’s card: the Suresult L24Pro 92.4, L20 89.3, L24 86.4, L14Pro 83.6 and L14 75.5, and the Clarius L15 HD3 64.0. The Suresult card leads with the L20Pro, which outscores the L24Pro on depth, 40 mm against 25 mm, and on five-year cost; the Clarius card leads with the L20 HD3, whose 20 MHz band outscores the L15 HD3’s 15 MHz.

I reran the order seven ways, as declared, and under fourteen alternative readings of the sources; the Suresult card stays first and the Clarius L20 HD3 second in every one. The table gives the declared run, the seven reruns and the three readings least favorable to the Suresult card, RC12 to RC14, where its lead is smallest: 6.01 points on the L20Pro and 3.45 on the L24Pro. Rival prices were read on October 31, 2026, and the rival plans and tool lists between October 28 and 31.
