Thyroid nodules color Doppler ultrasound is used to observe the size of the thyroid, blood flow signals, etc., but also to determine whether the nodule has calcification, whether it has increased, and whether there are adhesions between the surrounding tissues. If the nodule is suspected to be malignant, it is best to further make a needle biopsy diagnosis.
