Abstract:
ObjectiveTo compare the performance of color Doppler utrasonography (CDUS) alone,magnetic resonance imagine (MRI) alone, and the combination of the two in the diagnosis of thyroid carcinona (TC). MethodsCDUS and MRI results of 54 focuses of carcinoma in 45 cases diagnosed as TC by postoperative pathological results were reviewed. The sensitivity of CDUS, MRI, and the combination of the two in the diagnosis of TC was compared. ResultsThe sensitivity of CDUS and MRI was 77.78％ (42/54)and 81.48％(44/54) respectively. The difference had no statistical significance (P ＞ 0.05 ). The specificity of CDUS and MRI was 88.17％ and 92.47％ respectively, the positive predictive value was 79.25％ and 86.27％ respectively,and the negative predictive value was 87.23％ and 89.58％ respectively. The sensitivity of the combination of CDUS and MRI was 94.44％ (51/54). The difference between the combination and CDUS or MRI alone had statistical significance( P ＜0.05). ConclusionsCDUS has higher detection rate than MRI in microcalcification of TC focus. However, MRI can show more clearly of the peripheral invasion and cervical lymph node metastasis.The combination of the two can improve the accuracy of TC diagnosis.
