Sonography
USG THYROID focuses on the thyroid gland itself, the butterfly-shaped gland low in the front of your neck, rather than the wider soft tissue around it. It's usually ordered after a physical exam finds a thyroid nodule, a lump within the gland, or notices the gland feels enlarged or irregular, a change called a goiter. This is the structural scan, reading the gland and any nodule's size, shape, and internal texture. It doesn't measure how much hormone your thyroid is making, which needs a separate blood test. Nodules picked up this way are common. Ultrasound finds one in a large share of adults when specifically looked for, and most turn out to be benign.
This scan checks the thyroid gland's size and shape, along with the size, shape, and internal texture of any nodule found within it. Your doctor uses these structural features, not hormone levels, to judge whether a nodule needs a needle sample or just monitoring.
The thyroid sits low in the front of your neck and regulates your body's metabolism. USG THYROID reads its structure directly: the gland's own size and shape, and the size, shape, and texture of any nodule found within it.
A nodule is simply a lump of tissue within the gland, and they're common. A doctor's hands-on exam picks up a nodule in a smaller share of adults, but ultrasound finds one in a much larger share when specifically looked for, and the large majority of these turn out to be benign.
This is a structural scan: it reads the gland's shape, size, and internal texture, along with features like a nodule's edges and any tiny calcium flecks inside it. It doesn't tell your doctor whether your thyroid is producing too much or too little hormone, which needs a separate blood test read alongside this scan.
If a nodule's combined features raise enough concern, your doctor may recommend a needle sample taken directly from it, guided by the same ultrasound.
No. This scan reads the gland's structure, not its function. Whether your thyroid is making too much or too little hormone needs a separate blood test.
Very common. Ultrasound finds a nodule in a large share of adults when specifically looked for, far more than a doctor's hands-on exam alone would catch, and most turn out to be benign.
No. Most thyroid nodules found this way are benign. Your doctor looks at the nodule's size, shape, and internal features together before deciding whether anything further is needed.
Only if the nodule's combined features raise enough concern. Many nodules are simply monitored with a repeat scan instead.

No, it's painless. A probe with gel is moved gently over your neck.
No. It's an ultrasound-based scan using sound waves, with no radiation exposure.
There's no special preparation needed for most patients. Ask your doctor or the centre directly if anything specific applies to you.
