> Elastography is an ultrasound technique that measures thyroid tissue stiffness. How it helps assess nodules alongside standard ultrasound.

Elastography is an advanced ultrasound technique that estimates how stiff tissue is. Because some cancers are stiffer than normal thyroid tissue, elastography can provide extra information when assessing a nodule.
It is used as an adjunct to standard ultrasound and, where needed, biopsy — not as a replacement.

## How it works

Elastography applies gentle pressure or sound waves and measures how much the tissue deforms. Stiffer tissue deforms less. The results are displayed as a colour map or a stiffness value.
The scan is painless and performed in the same session as a standard thyroid ultrasound.

## When it may help

Elastography may add information when ultrasound features are borderline, or when deciding whether a nodule warrants biopsy. It can also help distinguish some benign from suspicious nodules.
Guidelines generally regard it as supplementary, because standard ultrasound features remain the primary risk assessment tool.

## Limitations

Results can vary with the operator, the nodule’s composition and calcification, and the technique used. Cysts and heavily calcified nodules are difficult to assess.
A suspicious elastography result still requires cytological evaluation in most cases.

## What to expect

No special preparation is needed. The scan takes only a few minutes and is combined with conventional ultrasound. The report is interpreted with the rest of your assessment.

## Frequently asked questions

### Is elastography better than ultrasound?

No — it is an add-on to standard ultrasound, not a replacement. Standard ultrasound remains the main tool for assessing nodules.

### Can it avoid a biopsy?

Sometimes it adds confidence, but it does not reliably replace biopsy when biopsy is indicated.

### Is the scan painful?

No — it is painless and performed like a normal ultrasound.

### Is it available everywhere?

Not all centres offer it. Standard ultrasound and, where needed, FNAC remain the core assessment.
