Whitepaper & user reports
Thyroid nodules are very common. While ultrasound has a high sensitivity for the detection of thyroid lesions, its specificity - the ability to differentiate between benign and malignant nodules - is limited. Color Doppler can provide information on hypervascularity, one of the most prominent features of malignancy, albeit not reliably. That means, neither general ultrasound nor color Doppler offers high sensitivity and specificity.
