目的探讨超声、CT、MRI在甲状腺良恶性结节鉴别诊断中的应用价值。方法选取我院收治的甲状腺结节患者63例作为研究对象，所有患者均行超声、CT、MRI检查，并给予手术治疗，以术后病理检查结果为金标准，评价这三种检查方法诊断甲状腺结节良恶性的灵敏度、特异度、诊断符合率。结果术后病理检查结果显示，63例患者中良性结节44例、恶性结节19例。超声诊断甲状腺结节良恶性的灵敏度、特异度和诊断符合率分别为63.16%、68.18%和66.67%；CT诊断甲状腺结节良恶性的灵敏度、特异度和诊断符合率分别为78.95%、95.45%和90.48%；MRI诊断甲状腺结节良恶性的灵敏度、特异度和诊断符合率分别为73.68%、90.91%和85.71%。超声、CT、MRI诊断甲状腺结节良恶性的ROC曲线下面积分别为0.920、0.947和0.974。结论超声、CT、MR检查诊断甲状腺结节良恶性的价值均较高, CT检查诊断的灵敏度和特异度均高于超声和MRI检查。

ObjectiveTo investigate the value of ultrasound, CT and MRI in the differential diagnosis of benign and malignant thyroid nodules. Methods63 patients with thyroid nodules admitted to our hospital were selected as subjects. All patients underwent ultrasound, CT, MRI, who also treated by surgery. The results of postoperative pathological examination were used as the gold standard. The sensitivity, specificity and coincidence rate of these three methods for diagnosis of benign and malignant thyroid nodules were evaluated. ResultsPostoperative pathological examination showed that there were 44 benign nodules and 19 malignant nodules in 63 patients. Diagnosing the sensitivity, specificity, and diagnostic compliance of benign and malignant thyroid nodules, the results of ultrasound were 63.16% and 68.18%, 66.67%; the results of CT were 78.95%, 95.45% and 90.48%; the results of MRI were 73.68%, 90.91% and 85.71%. The areas under the ROC curve for the diagnosis of benign and malignant thyroid nodules by ultrasound, CT and MRI were 0.920, 0.947 and 0.974, respectively. ConclusionUltrasound, CT and MR in the diagnosis of benign and malignant thyroid nodules has high value. The sensitivity and specificity of CT diagnosis are higher than those of ultrasound and MRI.
