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 To investigate the diagnostic value of MSCT hepatic capsule invasion in the diagnosis of liver cancer microvascular invasion (MVI). Methods Retrospective analysis of newly diagnosed pathologically confirmed single liver cancer in 132 cases, all cases underwent MSCT plain and multi-phase enhanced scan. MSCT hepatic capsule encroachment signs and surgical pathology results were analyzed. Results The signs of invasion of MSCT hepatic capsule and pathological hepatic capsule invasion and MVI of liver cancer were significantly correlated (P <0.01). The sensitivity, specificity and accuracy of MSCT hepatic capsule invasion were 83.3% 40/48), 67.9% (57/84), 73.5% (97/132). Conclusion The signs of MSCT hepatic capsule invasion can be used as a basis to evaluate MVI of liver cancer.
