Abstract：【Objective】 To investigate the characteristics of color Doppler ultrasonography (CDFI) in the differential diagnosis of thyroid carcinoma. 【Methods】A retrospective analysis of the CDFI data of 137 patients (169 nodules) which were confirmed by pathological examination in our hospital. Among them, there were 82 cases (101 nodules) of thyroid carcinoma and 55 patients (68 nodules) with benign thyroid nodules. CDFI features of thyroid carcinoma nodules and benign nodules were compared to reveal its diagnostic value to identify benign and malignant nodules.【Results】The rate of nodal fuzzy boundaries, calcification rate, low echo rate, grade Ⅱ~Ⅲ blood flow rate, rate of resistance index (RI)<0.7, lymph node enlargement rate were 61.39%, 76.24%, 74.26%, 66.34%, 62.38%, 45.54%, respectively, in thyroid cancer nodules. These were higher than those of the benign nodules 16.18%, 27.94%, 26.47%, 25%, 35.29%, 11.76%, respectively. The differences were statistically significant (P<0.05). Thyroid cancer nodules appeared 35.64% of halo rate and 31.68% of rear attenuation rate, which were lower than those of benign nodules (75%, 55.88%, respectively) and the difference was statistically significant (P<0.05). The sensitivity of CDFI in differential diagnosis of thyroid cancer nodules was 77.23%, the specificity was 80.88%, and the missed diagnosis rate was 22.77%, the misdiagnosis rate was 19.12%.【Conclusion】There are significant differences in CDFI features between benign and malignant thyroid nodules, which is of great value in the differential diagnosis of thyroid carcinoma.
