The diagnosis of liver tumors should be utilized for determination of not only the number of lesions, but also their size, segmental location and extent, and the relationship of the mass or masses to the hepatic vasculature. CT during arterial portography (CTAP) is the most sensitive imaging modality for precise diagnosis of hepatocellular carcinoma. CTAP is thus widely used as a diagnostic imaging technique, particularly for the detection of small hepatocellular carcinomas. Conventional splenic portography has been carried out for many years using a wide diameter needle, a large amount of contrast medium and a film-screen system. Since the development of arterial portography, fewer splenoportograms have been performed due to the high incidence of bleeding and other complications. In this study a 0.6-mm (23 gauge) thin needle was used for splenic puncture and CT was used as a detector instead of a film-screen system. With this technique CT during percutaneous transsplenic portography may be performed on an outpatient basis.
肝脏肿瘤的诊断不仅应确定病变的数量，还应确定其大小、节段位置和范围，以及肿块与肝血管系统的关系。动脉门静脉造影CT（CTAP）是精确诊断肝细胞癌最敏感的成像方式。因此，CTAP被广泛用作诊断成像技术，尤其是用于检测小肝细胞癌。传统的脾门静脉造影已经使用大口径针头、大量造影剂和屏-片系统进行了多年。自从动脉门静脉造影发展以来，由于出血和其他并发症的高发生率，脾门静脉造影的操作次数减少。在本研究中，使用0.6毫米（23号）细针进行脾穿刺，并使用CT作为探测器代替屏-片系统。采用这种技术，经皮经脾门静脉造影CT可以在门诊进行。
