# Sonoelastography in differentiating benign and malignant thyroid nodules: A histopathological correlation

## TL;DR

This study shows that sonoelastography can help tell the difference between benign and malignant thyroid nodules, potentially reducing the need for biopsies.

## Contribution

The study introduces a new cutoff value for ARFI imaging to improve thyroid nodule classification accuracy.

## Key findings

- Malignant thyroid nodules had significantly higher ARFI values than benign ones.
- Using a 2.8 m/s cutoff, ARFI achieved high sensitivity and specificity in differentiating nodules.
- Combining ARFI with conventional ultrasound improved diagnostic accuracy.

## Abstract

Thyroid nodules are common and distinguishing benign from malignant ones is essential for optimal management. This cross-sectional
study of 120 patients assessed Acoustic Radiation Force Impulse (ARFI) imaging in differentiating thyroid nodules, correlating results
with histopathology. Malignant nodules showed higher mean ARFI values (3.59 ± 0.7 m/s) than benign ones (1.98 ± 0.31 m/s).
With a 2.8 m/s cutoff, ARFI achieved 92.6% sensitivity and 92.9% specificity. Combining ARFI with conventional ultrasound improved
diagnostic accuracy, highlighting its potential to reduce unnecessary biopsies.
