> Thyroid ultrasound imaging — evaluate nodules, goitre, cysts and thyroid structure. Painless, non-invasive, no radiation.

Thyroid ultrasound is a painless, non-invasive imaging test that evaluates the structure of the thyroid gland and surrounding neck tissues.
It is the primary imaging tool for thyroid nodules, goitre, and suspected structural problems.

## What the scan shows

Ultrasound reveals gland size, texture, and any nodules — their number, size, composition, and suspicious features. It also detects cysts, enlarged lymph nodes, and inflammatory changes.
Results typically take minutes; a gel is applied to the neck and a probe glides over the area.

## When ultrasound is recommended

Palpable neck lumps, visible goitre, abnormal thyroid function tests with structural suspicion, monitoring known nodules, or pre-biopsy evaluation. It is not needed for every thyroid patient — clinical judgment guides its use.

## After the scan

Images and a report are provided. Findings are interpreted alongside blood tests and examination — a suspicious nodule may need FNAC, while benign-appearing nodules are monitored.

## Frequently asked questions

### Is the procedure uncomfortable?

No — it is completely painless. You lie still while a gel and probe are used on the neck; it takes about 15–30 minutes.

### Do I need any preparation?

No special preparation — you can eat and take medications normally before the scan.

### Can ultrasound diagnose cancer?

It identifies suspicious features that warrant biopsy but cannot definitively diagnose cancer — FNAC provides cellular diagnosis.
