| 摘 要： | 目的探讨多层螺旋CT（MSCT）与MRI在甲状腺结节鉴别诊断的应用价值。方法选取2018年3月~2019年10月于我院收治的甲状腺结节患者并经手术后取得病理诊断结果的94例患者（94个结节）作为研究对象，对入组患者均行MSCT和MRI检查，以病理组织学检查为金标准，比较两种检查方法的诊断结果，计算两种检查方法的敏感度、特异度、准确率、阳性预测值、阴性预测值和kappa值。结果94例甲状腺结节患者中，73例（77.66%）诊断为良性结节，21例（22.34%）为恶性结节。MSCT诊断甲状腺结节良恶性的灵敏度、特异度、准确率、阳性预测值、阴性预测值与MRI检查相比差异均无统计学意义（P>0.05），但MSCT诊断与病理诊断的Kappa值为0.746，大于MRI诊断与病理诊断的Kappa值为0.737。结论MSCT与MRI诊断甲状腺结节良恶性的灵敏度、特异度、准确率均较高，与病理学诊断结果均具有较高的一致性，具有较高的临床应用价值，而MSCT在诊断甲状腺恶性结节钙化方面更具优势。

| Abstract: | ObjectiveTo explore the application value of multi-slice spiral CT (MSCT) and MRI in the differential diagnosis of thyroid nodules.Methods94 thyroid nodules patients (94 nodules) admitted to the hospital from March 2018 to October 2019 and obtained pathological diagnosis results after surgery were enrolled as the research objects. All patients underwent MSCT and MRI examination. Taking histopathological examination as the golden standard, the diagnosis results of the two examination methods were compared. The sensitivity, specificity, accuracy, positive predictive value, negative predictive value and kappa value of the two examination methods were calculated.ResultsIn 94 cases of thyroid nodules, 73 cases (77.66%) were diagnosed as benign nodules, 21 cases (22.34%) as malignant nodules. There were no significant differences in sensitivity, specificity, accuracy, positive predictive value and negative predictive value between MSCT and MRI for diagnosis of benign and malignant thyroid nodules (P>0.05). However, the kappa value of MSCT diagnosis and pathological diagnosis was 0.746, which was higher than that of MRI diagnosis and pathological diagnosis (0.737).ConclusionThe sensitivity, specificity and accuracy of both MSCT and MRI are high in the diagnosis of benign and malignant thyroid nodules. They are highly consistent with the pathological diagnosis results and have high clinical application value. However, MSCT is more advantageous in diagnosis of malignant thyroid nodules calcification. |
