簡単な回答
A thyroid nodule is a discrete focus that starts and stops inside otherwise uniform gland, and what decides the next step is never one look at it — it is five scored features plus one measurement. Put the linear array on the front of the neck, lower than instinct says, because the gland sits well below the thyroid cartilage rather than at it. Sweep the lobe in two planes at about 40 mm of depth. A nodule appears, grows and vanishes within a few millimetres of travel; a vessel keeps running as you follow it, and fills on colour or power Doppler. Once you have one, measure it in three axes off the cine buffer and score it: composition, echogenicity, shape, margin, echogenic foci. The points are added, the total lands in one of five ACR levels, and each level carries its own biopsy size and its own follow-up size. The nodule scanned in this recording totals zero points and measures 4 × 4 × 5 mm, which is benign with no needle and no follow-up scan. I would learn the sweep before the score, because a score is worthless applied to something you have not really found, and the two artefacts on screen here — a dark column that looks like a cleft, and an edge effect beside a vessel — are exactly what gets scored by mistake. Start at 4:20 for the scanning and 9:33 for the scoring.
If the question is the hardware rather than the exam, the endocrinology hub covers what small-parts work asks of a probe, and the D3Ultra page carries the full specification and the current price.

The American College of Radiology system scores five things about a nodule and adds the points up. Here is what each category can contribute, and what this nodule was called in each. Every card jumps the video to the moment it is argued.

The chart itself belongs to the ACR and is linked under Sources rather than reproduced here. Two things about this case deserve saying plainly. It is Ramakko’s own thyroid, which he says at 0:20, so the case is a volunteer with a known nodule rather than a referral. And that nodule is anechoic, smooth and 5 mm, which is the easy end of all five scales at once. A solid, very hypoechoic, taller-than-wide nodule with punctate foci scores eleven, lands in the top level, and is sampled from 1 cm. The system earns its keep on that one, not on this one.

Key moments, with the settings
The third column is the part a scan video usually leaves out: the preset, depth, frequency and gain showing on the device panel at that moment. On this recording they are chosen before the first sweep and then never touched again — one preset, one depth, one frequency, one gain, for the whole gland. The only control that moves at all is compound imaging, switched on at 6:18 and off again before the sweep resumes.

Reading the images
What this scan shows
Thyroid tissue is the easiest parenchyma in the neck to read, because normal is so uniform. At 10 MHz the gland fills with fine, even speckle, a little brighter than the strap muscles lying over it, and anything that interrupts that evenness is worth a second look. Most of what interrupts it is not a nodule.
Both of those interruptions are in the frame above. A round black structure inside or beside the gland could be a nodule and is usually a vessel: slide along it and the vessel keeps going while a nodule ends, and colour or power Doppler settles the argument in a second. The dark column next to it is fascial shadowing, and it is the finding I see mistaken for a real defect most often. Neither one gets scored.
What does get scored is a discrete focus with edges — and the moment you find one, the measurement convention starts to matter. The ACR system defines taller-than-wide on the transverse image, with the height measured parallel to the beam and the width perpendicular to it. So the 4 mm anterior-to-posterior dimension here is the height, and the 5 mm superior-to-inferior one is not a candidate for it at all. That is why a nodule whose largest single number is 5 mm is still wider than tall and scores nothing for shape. Read the plane wrong and you have invented three points and moved a benign nodule two levels up the chart.

Why this scan, and on whom
0:00Hello. Today we’re going to use a Suresult D3Ultra handheld ultrasound to investigate the thyroid gland, looking for nodules. Nodules are very common — most people have nodules. They’re normally benign, but not always. So we’re actually going to do this on myself. Typically I use my wife as the sample patient for these videos, but her thyroid is boring — it’s normal. I have a thyroid nodule. So not only are we going to scan and find it, and take measurements, but we’re going to see: should I worry about this, and do I need an aspiration or not? And I’ll cover the requirements and the guidelines as to what to do when you’re looking for nodules, and whether follow-ups are necessary and whether aspiration is necessary.
0:48In terms of patient positioning, typically the patient is supine on an examination bed or table and the sonographer or the doctor is standing next to them, or sitting next to them. But there’s a little bit of a problem with that position. It’s fine — you have good access to the thyroid gland — but you have to be careful with your arm. I’ve heard of complaints, particularly from female patients, that the sonographer or the doctor molested them. You can imagine: if you’re here, where does your arm rest? The doctor’s arm is going to rest on the breast. So be very careful with your positioning. I like actually the sitting position, so I’ll place the patient in a chair and I’ll stand behind them. I can have the screen in front of both the patient and myself, so we’re both looking at the screen together, and that’s a very comfortable position to scan from. The other position that works very well is the patient face up, so supine, again — this works well with a chiropractic table where there’s space at the top of the table. So I sit behind them, and it’s very similar to the seated position. And again, there’s no way I can accidentally brush up against someone’s breast from that position.
Probe, frequency and what a bedside study documents
2:03Now, the thyroid is a relatively shallow structure, so we’re going to be using the linear side of the transducer. You want to use a relatively high frequency, something in between maybe 10 to 15 megahertz, for checking out the thyroid. If you haven’t evaluated the thyroid before, a lot of people think it’s higher than it is, because the thyroid cartilage is way up here but the thyroid gland is much, much lower. So just keep that in mind.
2:35And let’s talk protocols and documentation just for a moment. As a point-of-care practitioner, I often have a clinical question in mind and I’m just scanning to answer that clinical question. These series of videos are: I have one question, I’m going to scan it just enough so that I can answer that one clinical question. Sonographers, particularly the technicians, might just be taking pictures to send to a radiologist who will then evaluate the pictures, so they have a list of pictures that they need to take. Whereas for myself, particularly if it’s normal, I might just take a couple of images just to prove that I did scan it, but I’m not necessarily following a protocol. I don’t have a set number of pictures I need to take, and on different days and for different people I take different pictures, because I might have different clinical questions. The typical protocol for a sonographer is: they might come in sagittal, measure the dimensions lengthwise and take a picture; they go in a transverse plane, again they measure the dimensions and take a picture; take a picture superior, take a picture inferior, screen through, done. But for us, particularly for this video, I don’t care about the dimensions of the thyroid. I am looking for nodules. If I find a nodule, then I’m going to take measurements of that nodule. I don’t really care about the overall size of the thyroid, because that isn’t my clinical question today.
3:52And a general rule of thumb is to screen through structures in two planes. Basically you could screen through in this direction and screen through in this direction. And then if anything looks wrong — if I see a nodule — that’s where I go in both planes and I take measurements of the nodule. And we need those measurements of the nodule to determine whether we need follow-up, whether this might be malignant or not.
The gland on screen
4:20Okay, so let’s scan my thyroid. As I mentioned, I should have a nodule somewhere, so let’s find it and evaluate it. I just need some gel on the unit here. Should be plenty. And let’s see what we see. Okay. There’s a few things to talk about already. So what are we looking at? This here is our thyroid gland, and that is an artery.
4:56Now, to identify the vessels: a nodule is going to appear and disappear as you screen through it, because it’s small, or it’s round or oblong — it has a finite size. Blood vessels will continue; you can follow it up, up, up, and you can follow it down, down, down. The other thing you can do is you can turn on colour Doppler or power Doppler, and of course the blood vessels are going to pulse because they have fluid in them, whereas you don’t expect that pulsatile flow through the entire nodule. So that’s another way to distinguish a blood vessel from a nodule.
5:32The other thing you’ll notice is the sort of edge effects here, sometimes called refraction artifacts, here with the blood vessel. We also have a bit of a shadowing artifact here. So my thyroid gland doesn’t actually have a shadowed section within it. This isn’t a cleft; it isn’t cut in two. What’s happened is that because of all this fascial tissue right here, this is preventing some of the sound beams coming this way from going into this region. So fewer sound beams from this area are reaching back to the transducer, and so the area appears darker than it should be. So this is an imaging artifact. This is nice and uniform thyroid tissue. This is normal thyroid tissue.
6:18Now if you want, you can turn on — I have just normal B-mode on — so you can even try compound imaging if you don’t like this speckled appearance. It’ll smooth things out, but at the cost of some frame rate. And there are different types of compound imaging; I believe this is frequency compounding instead of spatial. Spatial compound imaging can sometimes prevent some of that fascial shadowing artifact from appearing. So this is compound imaging on, and I can turn it back off. I prefer it off unless I’m taking a really nice-looking picture; if I want a nice-looking picture I’ll turn compound imaging on, because sometimes it gives you better-looking pictures.
Finding the nodule, and measuring it
7:02So let’s find that nodule. I can screen all the way up to the top and I can follow it down, and I get a little bit of that artifact. Oh, what the heck is that? A dark circle appears and winks in and out of existence. That’s not normal. Let’s finish screening — screen all the way down, all the way down, all the way down. And there’s nothing else funny going on, just that one tiny nodule.
7:35Okay, so let’s go to that nodule. So it’s sometimes difficult to get that perfect picture, but remember you can record cine clips with the software here. I can just swipe left and right and I can go through the individual frames, so I can try to find the best frame for taking measurements. And we want the largest measurements, so maybe that would give us the best measurements. So I can at least get two measurements here — some lengths — and a lot of the guidelines, you want the largest measurements. So 4 millimetres there. I can get another length here, and also 4 millimetres. So it’s 4 millimetres by 4 millimetres so far.
8:33And we have to of course go in the other axis and see what it is in that axis. So I can save this image, and then I’m going to go in the other axis. Here we go. And you can screen through in this axis, see if there’s anything strange. And right away you can see where that nodule is. Maybe that’s the best picture of it there. Let’s take a measurement of that. So it’s about five. So it’s four by four by five. So not that big.
Scoring it
9:13So, do I have cancer? Is my thyroid nodule an issue? If you remember, the dimensions were 4 by 4 by 5 in terms of millimetres, so less than 1 centimetre large. You’ll learn if it’s less than 1 centimetre large, it’s probably not malignant.
9:33But there are guidelines, for example from the American College of Radiology. They have the TI-RADS chart, and you basically give points for the composition, the echogenicity, the shape, the margin, and whether there are echogenic foci. And you give points, and depending on how many points — you know, whether you need to follow up and monitor, because it’s a little suspicious, moderately suspicious, highly suspicious — whether you need an aspiration or not. Again, whether you need an aspiration: it’s how suspicious is it, and how big is it.
10:09So let’s quickly use my nodule as an example. Composition: cystic, or almost completely cystic, or spongiform — so it looks like a sponge — both those are zero points. So even if you have a nodule and it’s spongiform, that can be perfectly normal, probably benign. In fact there’s a special condition here that if it’s spongiform, if it looks like a sponge, don’t even bother calculating other points for other categories: it’s benign. So, mixed cystic and solid; solid and almost completely solid — mine was cystic, so zero points.
10:45Echogenicity: mine was black, mine was anechoic — zero points. Shape: wider than tall, or taller than wide. Now what they mean by tall is the anterior-to-posterior distance, and mine was 4 millimetres; the 5-millimetre measurement was superior to inferior. So mine is wider than tall, so it’s not tall — the tall isn’t the largest dimension. So zero points. So so far I’m zero, zero, zero. Margin: in one plane it looks smooth; in the other plane it has a little bit of irregularity to it, just a little bit. Maybe it’s ill-defined — so maybe I would call this ill-defined at worst. Zero points. So so far I’m zero, zero, zero, zero. Echogenic foci: are there microcalcifications, peripheral calcifications, comet-tail artifacts? We didn’t see any of this stuff, so zero points. So: zero points. Benign. Don’t worry about it.
11:45And if you want this chart, or a chart like this, there’s many charts like this online. And of course you can look up the original paper from the American College of Radiology. Or, for example, here’s a calculator — you just put it in and it tells you. It also summarizes some of the information for you from the research paper that created the TI-RADS classification, like how many points and what’s the risk of malignancy.
Follow-up, and closing
12:15Now, in terms of follow-ups: if it is getting worse — I know it says follow up at one, three, five years — if you follow up at one year and yeah, it jumped from a TI-RADS score of 3 to 4, don’t wait two years to follow up again. If it’s getting worse, follow up at least once a year, if it seems to be getting worse. I’ve actually seen a very large nodule, almost 3 centimetres I think in size, and I followed up a year later and it was gone. I couldn’t believe it. She couldn’t believe it; she’s like, you’re making a mistake. It’s like, no, it’s not there, I trust myself. So these things can get worse and they can actually get better.
13:03But it’s just as easy as that. The thyroid is one of the easiest things to check, and just following the TI-RADS chart is super easy. And I think if you have any suspicions and you have an ultrasound unit, why not check it out?

Hardware
Device and settings
One head, one preset, one set of numbers for the whole gland. The left column below is the published specification; the right is what the panel actually showed while this scan was running. Read the two together and one thing stands out. This array is the linear side of a three-geometry head and it tops out at 10 MHz, while Ramakko names 10 to 15 MHz as the band he wants for a thyroid — so the scan is being run at the floor of his own recommendation, and it still resolves a 4 mm anechoic focus cleanly enough to measure twice. That is the honest read of a multi-geometry probe on small parts: sufficient rather than optimal. A three-geometry head is not a good fit if thyroid, nerve and other small-parts work is most of your week: a dedicated high-frequency linear probe will out-resolve this one, and I would buy that instead. If the same head has to reach a kidney, a heart and a fetus in the same clinic day, the trade runs the other way and this is the probe I would carry.

Thyroid nodule questions
What does a thyroid nodule look like on ultrasound?
A nodule is a discrete focus inside otherwise uniform gland, and the giveaway is that it begins and ends. Sweep through the lobe and it appears, grows, shrinks and disappears, because it is a finite object. Its appearance is then described in five ways, which is exactly what the ACR system scores: what it is made of, how bright it is against the parenchyma around it, whether it is taller than it is wide, what its edge does, and whether it contains bright specks. The one in this recording is anechoic, smooth and wider than tall, which is the benign end of every one of those five scales. I would train on that appearance before hunting for the suspicious version of it, because the whole system is calibrated against normal.

How big does a thyroid nodule have to be before it gets biopsied?
Size alone never decides it. The ACR system pairs each risk level with its own size threshold: a mildly suspicious nodule is sampled at 2.5 cm and followed at 1.5 cm, a moderately suspicious one is sampled at 1.5 cm and followed at 1 cm, and a highly suspicious one is sampled at 1 cm and followed at 0.5 cm. Below those numbers the published recommendation is no biopsy and no imaging follow-up at all. Nothing scored benign or not suspicious is biopsied at any size. That is why the 4 by 4 by 5 mm nodule measured here needs neither: at 5 mm it sits under every biopsy threshold in the system.

Can ultrasound tell if a thyroid nodule is cancerous?
It cannot make the diagnosis, and it is not meant to. What it does is stratify risk well enough to decide who gets a needle, which is the stated purpose of the ACR system: thyroid nodules are extremely common and most turn out benign, so the scoring exists to stop the ones that will prove benign from being biopsied. Five sonographic features are scored, the points are added, and the total maps to one of five levels from benign to highly suspicious, each with its own biopsy and follow-up size. Cytology from a fine-needle aspiration is what confirms or excludes malignancy.

How do you tell a thyroid nodule from a blood vessel on ultrasound?
Follow it. A vessel keeps going as you slide the probe along the neck, up and down, while a nodule has ends and disappears within a few millimetres of travel. If that is not conclusive, put colour or power Doppler on it: the vessel fills and pulses, and a small nodule does not fill the same way. Both manoeuvres are demonstrated in the walkthrough at 4:56. A third giveaway is on the same frames, and it is the one that catches people out: the dark band running down through the gland beside the vessel is edge and fascial shadowing, not a cleft and not a lesion.
Read off the device panel and demonstrated by Brandon Ramakko, DC in the recording above.
What ultrasound settings do you use for a thyroid scan?
Shallow and high frequency, because the gland sits about a centimetre under the skin. The device in this recording ran its linear array on the thyroid preset at 40 mm depth and 10 MHz harmonic, gain 86 dB, dynamic range 60, compound imaging off, in B mode throughout, and none of that changed for the whole scan. The presenter names 10 to 15 MHz as the band he wants, so this array is sitting at the bottom of it. Compound imaging is worth knowing about but not worth leaving on: it smooths the speckle and costs frame rate, which is the wrong trade while you are still sweeping for something.
