摘要目的 探讨螺旋CT增强及延迟扫描诊断胆管细胞型肝癌的价值.方法 搜集经病理证实的27例胆管细胞型肝癌的螺旋CT平扫、增强及延迟扫描.结果 27例胆管细胞型肝癌平扫全部病灶为低密度,其中13例为囊性,14例为实质性且病灶内见胆管扩张13例,病灶远侧肝萎缩11例.增强扫描13例囊性病变中有9例出现病灶边缘不连续的较薄环形增强,3例连续环形强化,门静脉期12例均无变化,1例无增强表现.14例实质性病变在增强1 min后病灶出现延迟增强,密度等于或大于同层肝组织,扩张的胆管无变化.结论 螺旋CT增强扫描胆管细胞型肝癌具有特征性CT表现.

abstractsObjective To investigate the characteristics of enhanced and delayed CT of hepato-cholangio-carcinoma.Methods Conventional plus enhanced CT of 27 patients with pathologically proved hepatocholangio-carcinoma was retrospectively analyzed.Results The lesions of 27 patients with hepato-cholangiocarcinoma showed lower density in liver of 27 patients,these lesions had cystic area in13,parenchyma in 14,hepaticcholangiectasis in 13 and hepatetraphia of same lobule in11.Through enhanced scanning,12 cystic lesions had ring increase at edges including 9 uncoformity and 3 intrgrty,and those lesions showed unaltered in portal phases;1 cystic lesion was unenhanced.14 parenchyma lesions had endhancement on 1 minute after delayed scanning,and the density of these lesions was equal or super to liver tissue of same deck.The hepaticcholangiectasis were unenhanced.Conclusion Hepato-cholangio-carcinoma has characteristic CT feature.
