摘要
目的探讨MSCT肝包膜侵犯征象对肝癌微血管侵犯(MVI)的诊断价值。方法回顾性分析初诊经手术病理证实的单发肝癌132例,所有病例术前均行MSCT平扫及多期增强扫描。将MSCT肝包膜侵犯征象与手术病理结果进行对照分析。结果 MSCT肝包膜侵犯征象与病理肝包膜侵犯、肝癌MVI之间存在显著关联(P<0.01);MSCT肝包膜侵犯征象诊断肝癌MVI的敏感度、特异度、准确率分别为83.3%(40/48)、67.9%(57/84)、73.5%(97/132)。结论 MSCT肝包膜侵犯征象可以作为评估肝癌MVI的一种依据。
Objective The purpose of this retrospective study was to clarify the diagnostic value of radiologic hepatic capsular invasion on multiphasic MSCT for predicting the presence of microvascular invasion（ MVI） in hepatocellular carcinoma（ HCC）. Methods 132 patients with pathologically proved solitary hepatocellular carcinoma were retrospectively analyzed. All cases were performed on a multiphasic 64-MSCT scanner before operation. Radiologic evidences of hepatic capsular invasion were compared with surgical histopathology results. Results Radiologic hepatic capsular invasion was closely correlated with the presence of MVI and hepatic capsular invasion in histopathology. The presence of radiologic hepatic capsular invasion had a sensitivity of 83. 3%（ 40/48）,a specificity of 67. 9%（ 57/84）,and an accuracy rate of73. 5%（ 97/132） in predicting MVI. Conclusion The characteristics of hepatic capsular invasion on preoperative CT scans is a simple and effective noninvasive technique for detecting MVI.
