目的探讨多层螺旋CT(Multi-slice computed tomography,MSCT)扫描对于食管癌周围侵犯的诊断价值。方法 76例食管癌病人,术前均行MSCT平扫加增强,并将MSCT诊断结果与手术病理结果相对照。结果 76例食管癌中,MSCT对邻近结构有无受侵犯判断的准确率为89.47%,对淋巴结有无转移判断的准确率为88.16%。MSCT诊断邻近结构有无受侵犯以及淋巴结有无转移的结果与手术病理对照的一致性较好(Kappa值分别为0.784和0.761)。结论 MSCT扫描能有效评价食管癌邻近结构的侵犯情况以及有无淋巴结转移,是食管癌治疗前有价值的检查方法 。
Objective To investigate the diagnostic value of multi-slice computed tomography (MSCT) in the diagnosis of esophageal cancer. Methods 76 cases of esophageal cancer patients underwent MSCT scan plus contrast before operation. The results of MSCT were compared with those of surgical pathology. Results In 76 cases of esophageal cancer, the accuracy of MSCT in judging the adjacent structures was 89.47%, and the accuracy of judging lymph node metastasis was 88.16%. MSCT diagnosis of adjacent structures with or without invasion and lymph node metastasis results consistent with the surgical pathology control better (Kappa values were 0.784 and 0.761). Conclusion MSCT scan can effectively evaluate the adjacent structures of esophageal cancer and lymph node metastasis, is a valuable pre-treatment of esophageal cancer screening method.
