目的：探讨多层螺旋CT（MSCT）多期增强扫描对肝癌少见强化方式的影像分析及诊断价值。方法回顾性分析21例经手术病理证实或临床确诊的不典型强化的肝癌C T资料。结果21例中，小肝癌9例，结节型10例，巨块型2例。平扫17例呈低密度，4例呈等密度，瘤内密度均匀16例，5例密度不均匀。多期增强检查21例中，动脉期5例呈低密度，等密度4例，高密度12例。门脉期7例呈高密度，10例呈等密度，4例病灶呈低密度。延迟期1例呈高密度，2例呈等密度，18例呈低密度。结论 M SC T的多期增强扫描能反映出肝癌少见的强化方式，对其诊断及鉴别有着重要的意义。

Objective To investigate the imaging analysis and diagnostic value of multi‐phase enhancement scanning with multi‐slice spiral CT for the atypically enhanced hepatocellular carcinoma .Methods CT data of 21 cases of the atypically enhanced hepatocellular carcinoma confirmed by operation and pathology were retrospectively analyzed in this work .Re‐sults Of those 21 cases ,9 cases were small hepatocellular carcinoma ,10 cases were nodular type ,and 2 cases were mas‐sive type .On plain scanning ,17 cases were shown low density ,4 cases were shown isodensity ,16 cases were shown hom‐ogeneous density ,and 5 cases were shown uneven density .Of 21 cases underwent multi phase enhanced examination ,in arterial phase ,5 cases were shown low density ,4 cases were shown equal density ,and 12 cases were shown high density ;in the portal venous phase ,7 cases were shown high density ,10 cases were shown isodensity ,and 4 cases were shown low density ;and in delay phase ,1 case was shown high density ,2 cases were shown isodensity ,and 18 cases were shown low density .Conclusion Multi‐phase enhancement scanning with multi‐slice spiral CT can reflect the rare way of strengthe‐ning for hepatoma ,which has important significance to the diagnosis and differential diagnosis .
