螺旋CT肝双期扫描在外生性肝癌诊断中的临床应用

Value of hepatic dual phase helical CT scanning in diagnosis of pedunculated hepatocellular carcinoma

目的 :探讨螺旋CT肝双期扫描对外生性肝癌的诊断价值。方法 :回顾性分析了 7例外生性肝癌螺旋CT肝双期扫描的CT表现。结果 :7例外生性肝癌与肝脏相连 ,3例有明显蒂部 ,2例肝右叶外生性肝癌向下至右侧盆腔内 ,6例其内可见CT“密度更低区” ,3例压迫胃体及胃窦。螺旋CT肝动脉期 6例肿瘤内可见不规则纡曲强化血管影。5例门静脉期肿瘤呈低密度 ;2例门静脉期部分肿瘤组织强化 ,密度增高。结论 :螺旋CT肝双期扫描对外生性肝癌诊断有较高的临床价值。

Objective:To discuss the CT features of pedunculated hepatocellular carcinoma.Methods:The hepatic dual phase helical CT scanning of 7 cases of pedunculated hepatocellular carcinoma were reviewed retrospectively.Results:The pedunculated hepatocellular carcinoma was connected with liver(n=7),with well defined peduncle(n=3) and stretching to right pelvis(n=2),it showed hypodense areas within the tumor(n=6) and displacing of stomach (n=3).Enhanced tumor vessels were demonstrated during hepatic arterial phase(n=6).Enhanced tumor tissues were demonstrated during portal venous phase(n=2). Conclusion:Hepatic dual phase helical CT scanning is of great value in diagnosising pedunculated hepatocellular carcinoma.
