术前CT结合彩色多普勒超声对甲状腺乳头状癌颈部淋巴结转移的诊断价值

Diagnostic Value of Preoperative CT Combined with Color Doppler Ultrasound in Cervical Lymph Node Metastasis of Papillary Thyroid Carcinoma

目的探究术前计算机断层扫描(CT)结合彩色多普勒超声对甲状腺乳头状癌(PTC)颈部淋巴结转移的诊断价值。方法选择2016年1月-2018年10月我院收治的择期手术PTC颈部淋巴结转移患者78例,术前均行彩色多普勒超声、CT检查,比较不同检查方法及其联合应用对颈部淋巴结转移的诊断效能。结果彩色多普勒超声及CT+彩色多普勒超声检查诊断颈中央区、颈侧区淋巴结转移的敏感度及准确率均显著高于CT检查,差异有统计学意义(P<0.05),而特异度比较无显著差异(P>0.05);彩色多普勒超声与CT+彩色多普勒超声检查诊断颈中央区、颈侧区淋巴结转移的敏感度、特异度、准确率比较,差异均无统计学意义(P>0.05)。结论CT结合彩色多普勒超声检查对PTC患者颈部淋巴结转移的诊断更加全面精确。

Objective To investigate the diagnostic value of preoperative computed tomography(CT)combined with color Doppler ultrasound in cervical lymph node metastasis of papillary thyroid carcinoma(PTC).Methods 78 patients with cervical lymph node metastasis undergoing elective PTC in the hospital from January 2016 to October 2018 were enrolled.All patients underwent color Doppler ultrasound and CT before operation.The diagnostic efficiencies of different examination methods and their combined application for lymph node metastasis were compared.Results The sensitivity and accuracy of color Doppler ultrasound and CT combined with color Doppler ultrasound for the diagnosis of lymph node metastasis in cervical central area and cervical lateral area were significantly higher than those of CT(P<0.05).There was no significant difference in specificity between the above diagnostic methods(P>0.05).There was no significant difference in the sensitivity,specificity and accuracy for the diagnosis of lymph node metastasis in cervical central area and cervical lateral area between color Doppler ultrasound and CT combined with color Doppler ultrasound(P>0.05).Conclusion The diagnosis of CT combined with color Doppler ultrasound is more comprehensive and accurate for cervical lymph node metastasis in PTC patients.
