ObjectiveTo investigate the value of high frequency color Dopple ultrasound in the diagnose of thyroid cancer.MethodsHigh frequency color Dopple ultrasound was used to diagnose 30 cases of thyroid cancer who had proved by pathology, tumor size, echo , morphology, number , color blood flow and neck lymph node enlargemen were observed; Vmax, Vmin, RIt were measured.ResultsAmong 30 cases of thyroid cancer, 19 cases were papillary carcinoma, 6 cases were follicular carcinoma , 3 cases were medullary carcinoma, 2 cases were undifferentiated carcinoma . The Vmax, Vmin, RI in tumor side were significantly higher than that of the tumor-free side (P<0.05).ConclusionThe high-frequency color Doppler ultrasound can determine the number of thyroid cancer mass, location, size and presence of lymph nodes, and provide a reference for the diagnosis of thyroid cancer.
