Sonography
USG HIGH RESULATION refers to a technique, not one fixed body part: ultrasound done with a higher-frequency probe built for fine detail in structures right under the skin. Raising the frequency sharpens the image but shortens how deep the sound waves can reach, a direct trade-off. A 10 MHz probe, similar to what many general scans use, reaches roughly 35 millimetres deep, while a 20 MHz probe used for finer superficial detail reaches only about 10 millimetres. Your doctor chooses this higher-frequency approach specifically for shallow structures like skin, a small nodule, or a tendon, where fine detail matters more than seeing anything deep.
This scan uses a higher-frequency probe to get finer detail on a specific superficial structure your doctor has flagged, such as a small nodule, a patch of skin, or a tendon. Your doctor reads its size, shape, and texture in that added detail, though the probe can't see much deeper than a few centimetres.
Ultrasound frequency and image detail move together: a higher frequency gives a sharper picture but reaches a shorter distance into the body, and a lower frequency reaches deeper at the cost of fine detail. USG HIGH RESULATION uses probes tuned toward the higher end of that range specifically for structures close to the surface.
A 10 MHz probe, common for general superficial scanning, reaches about 35 millimetres deep. Push the frequency to 20 MHz and the reach drops to around 10 millimetres, though the image detail at that shallow depth improves sharply. Some very high-frequency probes used for the finest surface detail, like individual skin layers, stay within just a few millimetres of the surface.
Fine superficial detail matters most for structures like small skin lesions, tiny nodules just under the skin, or tendons close to the surface, where a standard-frequency probe wouldn't resolve the detail your doctor needs. It isn't the right tool for anything sitting deeper in the body, which needs a lower-frequency scan instead.
Ask your doctor which specific structure this technique is being used to examine, since the entry itself describes a method rather than one body part.
It means a higher-frequency probe is used, which sharpens the image of structures close to the surface. A 20 MHz probe, for example, gives finer detail than a standard 10 MHz probe.
Raising the frequency to sharpen image detail shortens how far the sound waves reach into the body. A 20 MHz probe reaches only about 10 millimetres deep, compared to roughly 35 millimetres for a 10 MHz probe.
Small, superficial structures like a skin lesion, a nodule just under the skin, or a tendon close to the surface are the kinds of findings this technique is chosen for.
No, it's still a painless probe-and-gel scan. The only difference is the specific probe used, not how the scan feels.

No. It's an ultrasound-based technique using sound waves, with no radiation exposure.
The higher-frequency probe used here trades depth for detail, showing shallow structures more sharply than a standard probe would, at the cost of seeing anything deeper.
There's no single preparation that applies to every structure this technique can be used on. Ask your doctor or the centre directly what they'd like you to do beforehand.
