plan: the scan shows where the facial arteries run in this patient, how deep they sit, which filler is already in the tissue and where the needle or cannula tip is. This guide covers that scan site by site, how common fillers look on screen and the frequency each facial layer needs. My first pick for filler work across the face is the Suresult L20Pro at {{SRX_PRICE:31250}}, with the L24Pro for lips and tear troughs and the L14Pro for body treatments.<\/p>\n<\/div>\n<section aria-label=\"Reviewed by Suresult clinical authors\" class=\"srx-author-panel sr-author-panel\">\n<p class=\"srx-author-kicker\">Written and clinically reviewed by<\/p>\n<div class=\"srx-author-list\">\n<article class=\"srx-author-card sr-author-card\" data-sr-author=\"fernando-mariz-md\">\n<span aria-label=\"Verified author\" class=\"srx-verified-badge\">\u2713<\/span><br \/>\n<img alt=\"Fernando Mariz, MD\" class=\"srx-author-portrait\" decoding=\"async\" height=\"72\" loading=\"lazy\" src=\"https:\/\/suresultmed.com\/wp-content\/uploads\/fernando-mariz-md-author-avatar.png\" width=\"72\"\/><\/p>\n<div>\n<p class=\"srx-author-name\">Fernando Mariz, MD<\/p>\n<p class=\"srx-author-role\">Gynecology, pelvic surgery, women\u2019s health and sonography<\/p>\n<\/div>\n<details class=\"srx-author-details\">\n<summary>About Dr. Mariz<\/summary>\n<p>I\u2019m Dr. Fernando Mariz, a gynecology and pelvic surgery physician practicing in New York City.

Its depth settings run from 10 to 40 mm, and the free Suresult app includes Color, Power and PW Doppler, Needle Enhance and DICOM export. For lips, tear troughs and superficial filler I choose the L24Pro at {{SRX_PRICE:30649}}; for body treatments and MSK beside facial work, the L14Pro at {{SRX_PRICE:31438}}. Each includes three months of FaceAtlas AI, which maps 21 facial points and recognizes seven filler materials. For reference, the Clarius L20 HD3 lists at $5,395 and needs its Essentials membership for PW Doppler and Needle Enhance.<\/p>\n<\/div>\n<\/section>\n<section class=\"sr-quick-list\">\n<h2>The Quick List<\/h2>\n<div data-sr-prose-slot=\"quick-list\">\n<ul>\n<li><strong>Whole-face artery mapping and injection:<\/strong> Suresult L20Pro, {{SRX_PRICE:31250}}<\/li>\n<li><strong>Lips, tear troughs and the glabella:<\/strong> Suresult L24Pro, {{SRX_PRICE:30649}}<\/li>\n<li><strong>Body treatments, MSK and vascular scans:<\/strong> Suresult L14Pro, {{SRX_PRICE:31438}}<\/li>\n<li><strong>The 192-element siblings:<\/strong> L20, L24 and L14, from {{SRX_PRICE:28577}}<\/li>\n<\/ul>\n<\/div>\n<\/section>\n<div class=\"sr-evalscope\" id=\"methodology\" data-sr-reviewer-scope>\n<div data-sr-prose-slot=\"method\">\n<p>This guide has two authors, both independent device reviewers with deep ultrasound knowledge. On October 27, 2026, I set eight probes against what filler work needs: the Suresult L20Pro, L24Pro and L14Pro, and five reference probes: the Philips Lumify L12-4, the GE Vscan Air SL, the Butterfly iQ3 and the Clarius L20 HD3 and L15 HD3. On the same date I checked every clinical figure on this page against its study&#39;s abstract or full text, and each study is numbered in Sources.

A scan gives its course in this patient. In a 2025 meta-analysis of ten Doppler studies, the facial artery ran medial to the nasolabial fold in 46.2%, crossed it in 22.5% and ran lateral to it in 12.0% of cases (Pourani 2025). At the glabella, frowning shifted the supratrochlear and supraorbital arteries medially, so the line an injector treats and the vessel beneath it keep no fixed relation (Cotofana 2020a).<\/p>\n<p>A 2025 modified Delphi consensus on ultrasound in aesthetic injectables set the working baseline. Its panel was fifteen experts from seven specialties and eleven countries (Velthuis 2025).<\/p>\n<ul>\n<li>Handheld devices are suitable both for learning and for regular diagnostics.<\/li>\n<li>B-mode, Color Doppler, Spectral Doppler and image and video archiving are mandatory, and Power Doppler is recommended.<\/li>\n<li>Imaging before injection is mandatory in certain areas with a high risk of vascular adverse events.<\/li>\n<li>Identify prior filler before injecting.<\/li>\n<li>Use ultrasound-guided injection in many parts of the face.<\/li>\n<\/ul>\n<\/div>\n<section id=\"workflows\">\n<h3>Scan before injecting, scan while injecting<\/h3>\n<div data-sr-prose-slot=\"workflows\">\n<p>The best-practice paper on the upper face names two workflows, &quot;scan before injecting&quot; and &quot;scan while injecting&quot; (Sigrist 2024). Each answers its own question, and a saved record closes the visit.<\/p>\n<ul>\n<li><strong>Before:<\/strong> Survey the treatment area in B-mode for existing filler, its depth and its plane. Switch to Color or Power Doppler, trace each artery through the planned entry points, and choose an entry point and plane clear of the vessel (Schelke 2018; Lee 2023).<\/li>\n<li><strong>While:<\/strong> Hold the probe over the target, follow the needle or cannula tip into the plane, then watch the product spread. In the temple, the same paper uses live imaging to confirm the cannula&#39;s plane (Sigrist 2024).<\/li>\n<li><strong>After:<\/strong> Save a still or cine loop of each deposit.

Arteries wider than 0.8 mm sat at the planned site in 34.7% of glabellas, 13.2% of nasolabial folds and 2.9% of temples. The series recorded no vascular complications (Teixeira 2025).<\/li>\n<\/ul>\n<p>Vascular events after filler are rare: a Dutch estimate put them at 1 in 6,558 procedures (Schelke 2020). A 2024 review of published cases of blindness after filler found no recovery of vision in 68.2% of the 318 cases with outcome data (Doyon 2024).<\/p>\n<\/div>\n<\/section>\n<\/section>\n<section id=\"equipment\">\n<h2>Probe features and software fees at a glance<\/h2>\n<div data-sr-prose-slot=\"equipment-intro\">\n<p>Filler work asks a probe for a top frequency of at least 15 MHz, Color and Spectral Doppler, a needle that shows clearly, and stored images and clips.

CDC tells clinics to use only single-use gel labeled sterile for scanning before or during any procedure that punctures the skin (CDC 2025), and UK guidance applies the same rule to the scan that maps a site for an injection planned within <span class=\"sr-nw\">24 hours<\/span> (UKHSA 2025).<\/p>\n<p>Gel left on the skin is hard to remove before antisepsis (Hudson 2022). A sterile gel pad solves both: the coupling is sterile, and nothing is left on the skin when the pad comes off. The Suresult pad, its price and its facts are under <a href=\"#gel\">Sterile gel pads for guided injection<\/a>.<\/p>\n<\/div>\n<\/section>\n<section id=\"artery-mapping\">\n<h2>Map the facial arteries before you inject<\/h2>\n<div data-sr-prose-slot=\"map-intro\">\n<p>Doppler ultrasound can detect almost all the arteries of the face before hyaluronic acid goes in (Lee 2023).

Rest the probe on a thick layer of gel or a gel pad with light pressure, because excessive pressure compresses the vessels (Teixeira 2025). Sweep slowly across the whole treatment area, switch to PW Doppler on each vessel you find to confirm an arterial waveform, and save the clip. The 20 MHz frames below were captured in a 20 mm window with a PRF of 1.0 kHz.<\/p>\n<\/div>\n<div class=\"sr-fi-atlas-gallery\">\n<figure><img src=\"https:\/\/suresultmed.com\/wp-content\/uploads\/ultrasound-guided-filler-injection-20mhz-color-doppler-vessel-20260728.webp\" width=\"2100\" height=\"1459\" alt=\"Suresult probe at 20 MHz, Color Doppler: flow in a superficial vessel, 20 mm window\" loading=\"lazy\" decoding=\"async\"><figcaption>Suresult probe at 20 MHz, Color Doppler: flow in a superficial vessel, 20 mm window<\/figcaption><\/figure>\n<figure><img src=\"https:\/\/suresultmed.com\/wp-content\/uploads\/high-frequency-ultrasound-20mhz-color-doppler-artery-vein-cross-section-20260729.webp\" width=\"2100\" height=\"1459\" alt=\"Suresult probe at 20 MHz: two adjacent superficial vessels in cross-section, red and blue on Color Doppler\" loading=\"lazy\" decoding=\"async\"><figcaption>Suresult probe at 20 MHz: two adjacent superficial vessels in cross-section, red and blue on Color Doppler<\/figcaption><\/figure>\n<\/div>\n<\/section>\n<section id=\"glabella-nose\">\n<h3>Glabella and nose<\/h3>\n<div data-sr-prose-slot=\"glabella-nose\">\n<p>In the 503-patient mapping series above, the glabella had the highest share of large arteries at the planned site: about one glabella in three had an artery wider than 0.8 mm there (Teixeira 2025). The supratrochlear artery sits about 3.3 mm under resting skin and moves when the patient frowns (Cotofana 2020a), so map and mark with the face at rest. On the nose, the dorsal nasal artery runs about 2.5 mm deep at the nasion (Ortiz Middleton 2025). Beside the nasal ala, in the deep pyriform space, the angular artery averaged 3.6 mm under the epidermis (Franceschelli 2024). A 2026 study combining Doppler and cadaver dissection found the nasal arterial network highly variable and asymmetric (Nguyen 2026). All of this sits in the first <span class=\"sr-nw\">5 mm<\/span>, where the 24 MHz of the L24Pro gives the finest detail.<\/p>\n<\/div>\n<\/section>\n<section id=\"lips\">\n<h3>Lips: find the labial arteries<\/h3>\n<div data-sr-prose-slot=\"lips\">\n<p>In 41 volunteers scanned by ultrasound, the superior labial artery averaged <span class=\"sr-nw\">5.6 mm<\/span> and the inferior labial artery <span class=\"sr-nw\">5.2 mm<\/span> below the skin. Both ran most often in the submucosal plane (58.5%), then within the orbicularis muscle (36.2%), and in the subcutaneous plane in 5.3% (Cotofana 2020b). A 2026 meta-analysis put pooled labial artery depths at 4.59 to 4.90 mm (Trzeciak 2026). A Doppler sweep along each lip shows which plane the artery takes in this patient before the first bolus, and B-mode shows any older product already in the lip.<\/p>\n<\/div>\n<\/section>\n<section id=\"tear-trough\">\n<h3>Tear trough: angular and infraorbital vessels<\/h3>\n<div data-sr-prose-slot=\"tear-trough\">\n<p>The best-practice paper on the midface maps the tear trough, nose, nasolabial fold and zygomatic region. Its example images show the infraorbital artery at 18 MHz and the tear trough at 20 MHz, and it singles out the angular artery near the nose in the medial tear trough (Vasconcelos-Berg 2024). The infraorbital artery&#39;s main trunk and its nasal and zygomaticomalar branches run in different planes (Hufschmidt 2019), so trace each branch from the foramen before placing product along the orbital rim. Existing filler in the tear trough shows on B-mode as a deposit the next treatment has to account for.<\/p>\n<\/div>\n<\/section>\n<section id=\"cheek\">\n<h3>Cheek: fat compartments and the facial artery<\/h3>\n<div data-sr-prose-slot=\"cheek\">\n<p>Over the zygoma, ultrasound shows the skin, subcutaneous tissue, SMAS, zygomatic muscles and bone, and the SMAS separates the superficial and deep fat compartments (Vasconcelos-Berg 2024). The same paper images superficial subcutaneous cheek tissue at 24 MHz. The facial artery deepens from 6.27 mm at the mandibular border to 8.04 mm at the lateral nasal ala (Pourani 2025). A 16\/20 MHz probe with a 40 mm window holds the cheek layers and the artery in one view, which is why the L20Pro is my default for midface and nasolabial work.<\/p>\n<\/div>\n<\/section>\n<section id=\"temple\">\n<h3>Temple: three planes and the temporal vessels<\/h3>\n<div data-sr-prose-slot=\"temple\">\n<p>The upper-face paper describes three injection planes in the temple: subdermal, interfascial between the temporal fascial layers, and supraperiosteal on bone (Sigrist 2024). Ultrasound maps the superficial and deep temporal vessels before injection and confirms the cannula&#39;s plane during it. Higher up, on the middle forehead along the vertical line through the lateral canthus, the frontal branch of the superficial temporal artery sat <span class=\"sr-nw\">2.7 mm<\/span> under the skin (Phumyoo 2020).<\/p>\n<\/div>\n<\/section>\n<\/section>\n<section id=\"reading-filler\">\n<h2>Recognize filler on ultrasound<\/h2>\n<div data-sr-prose-slot=\"filler-intro\">\n<p>Many faces arrive with product already in them, sometimes from another clinic and with no record. Sonography detects and identifies common cosmetic fillers (Wortsman 2015), and fillers generate different patterns of echogenicity and posterior acoustic artifact (Wortsman 2012). The 2025 consensus recommends identifying prior filler before injecting (Velthuis 2025).

Common fillers have recognizable patterns: hyaluronic acid forms anechoic or hypoechoic pseudocysts; CaHA shows bright deposits with acoustic shadowing; PMMA shows bright dots with comet-tail artifacts; silicone oil shows a snowstorm pattern. FaceAtlas AI Filler Scan recognizes seven materials: HA, collagen, PLLA, PCL, CaHA, PMMA and PVA.\"}}, {\"@type\": \"Question\", \"name\": \"Do you need Doppler for filler injections?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The 2025 Delphi consensus lists Color Doppler and Spectral Doppler as mandatory equipment for ultrasound in aesthetic injectables, and Power Doppler as recommended. All six Suresult L14, L20 and L24 probes run Color, Power and PW Doppler in the free Suresult app.\"}}, {\"@type\": \"Question\", \"name\": \"Can a handheld ultrasound be used for filler injections?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes. The 2025 Delphi consensus found handheld devices suitable for learning and for regular diagnostics. The Suresult L14Pro, L20Pro and L24Pro are wireless, weigh 145 g and scan for 4 hours per charge.\"}}, {\"@type\": \"Question\", \"name\": \"How is an ultrasound-guided filler injection different from ultrasound-guided dissolving?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Guided injection maps the vessels and places new product. Guided dissolving finds existing hyaluronic acid and places hyaluronidase directly into the deposit. In a 39-patient series, the targeted ultrasound-guided protocol used a mean 122.5 IU of hyaluronidase against 1,519.4 IU for flooding. The dissolving workflow has its own guide: ultrasound-guided filler dissolving.\"}}, {\"@type\": \"Question\", \"name\": \"Which Suresult probes include FaceAtlas AI?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The L14Pro, L20Pro and L24Pro each include three months of FaceAtlas AI.
