摘　　要：目的探讨高频彩色多普勒超声联合增强CT检查在甲状腺癌术后局部复发/残留诊断中的应用价值。方法回顾性分析2010年1月—2013年1月我院收治的67例疑似为甲状腺癌术后局部复发/残留患者的病例资料,67例患者术前分别行增强CT、超声联合增强CT检查,以病理诊断结果为"金标准",比较两种检查手段的准确价值。结果经病理诊断确诊为甲状腺癌术后复发/残留者63例(94.03%),术后单纯局部复发/残留结节17例(26.98%);单纯淋巴结转移31例(49.21%),局部复发/残留结节合并颈部淋巴结转移15例(23.81%);局部复发/残留结节患侧56例(88.89%),对侧7例(11.11%);超声联合增强CT的灵敏度、准确率高于增强CT,差异有统计学意义(P<0.05);两种检查手段的特异度、阳性预测值和阴性预测值比较,差异无统计学意义(P>0.05)。结论甲状腺癌术后局部复发/残留采用高频彩色多普勒超声联合增强CT进行诊断具有灵敏性好、准确率高的特点,临床上具有重要的诊断参考价值。Objective To investigate application value of high-frequency color Doppler ultrasound combined with enhanced CT in the diagnosis of postoperative local recurrence or residual in thyroid cancer after operation.Methods Retrospective analysis clinical data of 67 cases in our hospital from 2010 year January to 2013 year January who were suspected local recurrence/residues in thyroid cancer postoperative,and they were diagnosed using enhanced CT or ultrasound and enhanced CT preoperative respectively,compared with the diagnostic value between two groups when the pathologic diagnosis was＂gold standard＂diagnosis.Results 63patients（94.03%）were diagnosed as recurrent/residue in thyroid cancer postoperative by pathological diagnosis,17cases（26.98%）were local recurrence/residue after operation,31cases（49.21%）were only lymph node transform,15cases（23.81%）were local recurrence/residual with cervical lymph node transform.Local recurrence/residual nodules in the affected side was 56cases（88.89%）,and in offside was 7cases（11.11%）.Sensitivity,accuracy of ultrasound combined with enhanced CT were higher than those of enhanced CT,the difference was statistically significant（P〈0.05）;Specificity,positive predictive value,negative predictive value of two examination methods had no significant difference（P〉0.05）.Conclusion High-frequency color Doppler ultrasound combined with enhanced CT in the diagnosis of local recurrence/residue in thyroid cancer have the characteristic of good sensitivity,high accuracy,and it has very important clinical reference value.
