Testing two ultrasound methods to diagnose thyroid cancer

Doctors use ultrasound to find lumps (nodules) in the thyroid gland, but sometimes it's hard to tell if these lumps are cancer or not. This study is testing whether adding a special type of ultrasound called contrast-enhanced ultrasound—which shows blood flow in the nodule—can help doctors make better decisions about which nodules need a biopsy. Researchers are comparing two different scoring methods to see which one works better at catching thyroid cancer while avoiding unnecessary biopsies.

Currently, there is no standard way to combine regular ultrasound with contrast-enhanced ultrasound to diagnose thyroid cancer, which means doctors may order too many biopsies or miss some cancers. This study aims to find the best scoring method so doctors can more accurately tell benign nodules from cancerous ones.
