摘　　要：目的比较单独使用彩色多普勒超声（CDUS）、核磁共振（MRI）检查及2者并用对甲状腺癌的诊断价值。方法回顾性分析45例经病理确诊的54个甲状腺癌（TC）病灶的术前CDUS及MRI的影像资料，比较2者独立诊断及并用诊断TC的敏感性。结果CDUS及MRI诊断TC的敏感性分别为77．78％（42／54）和81．48％（44／54），差异无统计学意义（P〉0．05），特异性分别为88．17％和92．47％，约登指数分别为0．66和0．74，阳性预测值分别为79．25％和86．27％，阴性预测值分别为87．23％和89．58％；2者并用诊断的敏感性为94．44％（51／54），分别与其中单独一种方法比较，有统计学意义（P〈0．05）。结论CDUS对Tc病灶微钙化的检出优于MRI，MRI能较好地显示外周受侵情况及颈部淋巴结转移。2者结合可提高诊断TC的准确率。Objective To 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 carcinoma （TC）. Methods CDUS 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. Results The 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 MR/was 94.44% （51/54）. The difference between the combination and CDUS or MRI alone had statistical significance（P 〈 0.05）. Conclusions CDUS has higher detection rate than MRI in mieroealcification 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.
