摘要
目的探讨螺旋CT双期扫描对肝细胞癌的诊断价值。方法采用西门子SomatomBalance高速螺旋CT扫描机,对37例肝细胞癌患者进行螺旋CT双期扫描,高压注射器注射造影剂。全肝平扫后,分别于开始注射造影剂后25s,60s行全肝螺旋CT动脉、门静脉双期扫描。将螺旋CT扫描结果与普通CT扫描进行对照。其中男26例,女11例。年龄37岁～75岁,平均57.8岁。结果37例中,动脉期肿瘤明显强化31例,轻度强化6例,动—静脉瘘5例。门静脉期,肿瘤全部呈低密度。门静脉瘤栓11例。结论HCC螺旋CT动脉、门静脉双期增强扫描,病灶强化特征可反映其组织病理学改变的特点,诊断准确性高。
Objective To describe the appearances of hepatocellular carcinoma(HCC)using dual-phase liver protocol on spiral CT scanner.Methods Thirty-seven patients with HCC first underwent an unenhanced scanning covering the whole liver,then underwent arterial and portal venous scanning.The delay time was 25 sec and 60 sec after the injection of contrast media.The appearances of HCC on the spiral CT were compared with those on routine CT.Results In arterial phaes ,HCC lesions of hyper attenuated enhancement were found in 31 cascs.non-marked enhancement was perceived in 6 cases.A-V shunt was found in 6 cases.In portal venous phase,all the HCC lesions were demonstrated as hypo-attenuation.PV tumor thrombosis was seen in 15 cases.Conclusion The enhancement of HCC lesions on spiral CT dual-phase scanning can reflect the histopathologic characteristics.
