Diagnostic value of of thyroid carcinoma and benign nodule by ultrasound

Objective To explore the value of color Doppler ultrasonography in the differential diagnosis of thyroid carcinoma and benign nodule.Methods The interior blood features of 39 cases with thyroid carcinoma and 41 cases with benign nodules were observed by color Doppler ultrasonography,then RI and blood peak flow rate were measured.Results There was higher detection rate(grade 2 or grade 3) in thyroid carcinoma than that in benign nodules.The presences of penetrating vessel or branching vessel suggested thyroid carcinomas.RI of thyroid carcinoma group was higher than that of thyroid benign nodules group,there was significant differences between the two groups(P0.05).Conclusion Ultrasound has important clinical value in the differential diagnosis of thyroid carcinoma and benign nodule.
