多普勒超声联合多排螺旋CT在甲状腺结节良恶性鉴别中的应用价值

Application Value of Doppler Ultrasound Combined with Multi-slice Spiral CT in the Differential Diagnosis of Benign and Malignant Thyroid Nodules

目的探讨多普勒超声联合多排螺旋CT在甲状腺结节良恶性鉴别中的应用价值。方法回顾性分析我院2015年7月-2018年7月收治的60例甲状腺结节患者的临床资料。术前均接受多普勒超声和多排螺旋CT检查,保留有清晰完整的图像,良恶性经手术病理检查确诊。以手术病理检查结果为'金标准',评估多普勒超声、多排螺旋CT及联合检查对良恶性甲状腺结节的鉴别诊断价值。结果多普勒超声联合多排螺旋CT检查对良恶性甲状腺结节的灵敏度、准确率分别为95.12%、93.33%,均高于超声检查的80.49%、7 8. 9 5%,也高于C T检查的7 8. 0 5%、76.67%,差异有统计学意义(P<0.05)。结论多普勒超声联合多排螺旋CT检查可有效提升良恶性甲状腺结节的鉴别诊断准确性,减少误诊、漏诊的发生。

Objective To explore the application value of Doppler ultrasound combined with multi-slice spiral CT in the differential diagnosis of benign and malignant thyroid nodules.Methods The clinical data of 60 patients with thyroid nodules admitted to our hospital from July 2015 to July 2018 were retrospectively analyzed.Doppler ultrasound and multi-slice spiral CT were performed before surgery,and clear and complete images were retained,and benign and malignant lesions were confirmed by surgical pathology.The results of surgical pathology examination were taken as gold standard to evaluate the differential diagnosis value of Doppler ultrasound,multi-slice spiral CT and combined examination for benign and malignant thyroid nodules.Results The sensitivity and accuracy rate of Doppler ultrasound combined with multi-slice spiral CT for benign and malignant thyroid nodules were 95.12%and 93.33%respectively,which were higher than 80.49%and 78.95%of ultrasound examination and were also higher than 78.05%and 76.67%of CT examination(P<0.05).Conclusion Doppler ultrasound combined with multi-slice spiral CT can effectively improve the differential diagnosis accuracy of benign and malignant thyroid nodules,and reduce the occurrence of misdiagnosis and missed diagnosis.
