MSCT和DSA对原发性肝癌的影像诊断价值的对照

Role of Multi-slice CT and DSA in the Diagnosis of Primary Hepatocarcinoma

目的:评价多层螺旋CT和数字减影血管造影检查对原发性肝癌的诊断价值及临床指导意义。方法:对62 例原发性肝癌(PHC)患者进行肝脏MSCT和DSA检查,两种检查间隔时间为2-14 d。对比分析多层螺旋CT和DSA检查对PHC的诊断价值。结果:62例PHC病例中,巨块型14例,弥漫型及混合型42例,结节型6例。10例患者两种检查结果不一致,余52例影像学表现基本一致。DSA和MSCT检查均发现PHC合并门静脉主干及近端分支癌栓12例,此外,MSCT还显示2例外周分支癌栓。DSA检查发现PHC中肝动脉门静脉瘘(APS)形成26例,MSCT检查发现APS形成21例。结论:MSCT和DSA在原发性肝癌的影像诊断中各有特点,两者相结合对于PHC的诊断和综合治疗具有重要临床意义。

Objective：To evaluate the role of multi slice CT （MSCT） and DSA in the diagnosis and treatment planning of primary hepato-carcinoma （PHC）. Methods： The images of 62 patients with PHC having MSCT and DSA were retrospectively reviewed. The interval of these two examinations was 2- 14d. Results： ① Of the 62 patients with PHC, there were giant mass type （n=14）,diffuse and mixed type （n=42）,and nodular type （n=6）. The results of two examinations were inconsistent in 10 patients,in the rest 52 cases the results were basically coincident. ② In 12 cases of P HC,information of tumor associated with portal vein tumor thrombi in the main trunk and proximal branches was provided by DSA. How ever,in these 12 cases,apart from the above-mentioned tumor thrombi in the major portal veins,additional tumor thrombus within peripheral portal vein were detected by MSCT in 2 cases. ③ 26 cases having arterio-portal shunt （APS） were shown by DSA,while only 21 cases were revealed by MSCT. Conclusion： MSCT and DSA provided information from different as pects in the image diagnosis of PHC. Combination of information provided by these 2 modalities played an important role in the diagnosis and comprehensive treatment planning of PHC.
