超声与增强CT对甲状腺癌发生中央区淋巴结转移患者的诊断效果

目的探讨超声与增强CT在甲状腺癌发生中央区淋巴结转移患者中的诊断效果。方法回顾性分析2012年6月到2015年11月期间我院耳鼻喉科门诊和病房收治的113例甲状腺癌患者临床资料,所有患者术前均行颈部超声和增强CT检查,术中对超声和(或)增强CT提示转移的中央区淋巴结进行清扫,并与术后病理结果进行比较。结果 134侧甲状腺癌淋巴结转移,术后病理证实93侧颈部中央区淋巴结转移,41侧无颈部中央区淋巴结转移。超声检查灵敏度、准确性均优于CT增强扫描的灵敏度和准确性,二者比较差异有统计学意义(P0.05);但超声与CT增强两种检查方法特异度、阳性预测值、阴性预测值差异比较无统计学意义(P0.05)。结论对于甲状腺癌中央区淋巴结转移的诊断,超声的诊断效果优于增强CT,可作为首选检查方法;但超声和CT可互为补充进而准确诊断。。

Effect of Ultrasonography and Contrast-Enhanced Computer Tomography in the Diagnosis of Thyroid Carcinoma and Lymph Node Metastasis

Objective To explore the effect of ultrasonography and contrast-enhanced computer tomography in the diagnosis of thyroid carcinoma and lymph node metastasis. Methods Retrospective analysis 113 cases of clinical data of patients in our hospital with thyroid cancer from June 2012 to November 2015, all patients underwent ultrasound and enhanced CT, and Performed dissection to lymph trancfer intraoperative by ultrasound (or) enhanced CT prompt during the surgery, and compared the results with postoperative pathological.Results 93 side neck were confirmed metastasis by pathologically of central lymph node metastasis, and 41 side without lymph node metastasis. Sensitivity, accuracy of ultrasound was superior thanCT scan enhanced, the difference was statistically significant (P<0.05), but the difference of specificity, positive predictive value, negative predictive the value of ultrasonography and CT enhanced was not statistically significant (P>0.05).Conclusion For the diagnosis of thyroid cancer, and central lymph node metastasis, ultrasound is batter than enhanced CT, can be choose as a preferred method of examination, but ultrasound and CT can complement each other and accurate diagnosis.
