目的探讨一种新的检查方法-经牌门静脉造影CT（CTSP）在诊断原发性肝癌（PHC）中的应用。材料和方法为31例PHC患者行CSP检查，描述PHC在CTSP图像上的表现，并与病理及其他影像对照，评价CTSP诊断PHC的价值。结果31例PHC患者经CTSP检查，均清楚地显示了肝内肿瘤CTSP显示肝内1cm以上的占位病变，与手术检查结果一致，诊断优于普通增强CT，但对位于肝表面及肛门区1cm以下的小结节诊断有困难。对31例患者，除少数有局部轻微胀痛，其他无不适，无脾脏破裂及腹腔出血情况。结论CTSP是显示PHC的敏感方法；对肝内占位病变有鉴别作用；而且，CTSP应用也是安全的，在临床上可以选择应用。
Objective To investigate the application of CTSP in the diagnosis of primary liver cancer (PHC). Materials and Methods CSP examination was performed on 31 patients with PHC. The performance of PHC on CTSP images was described. The results were compared with pathology and other images to evaluate the value of CTSP in the diagnosis of PHC. Results The CTSP examination of 31 patients with PHC clearly showed that the intrahepatic tumor CTSP showed more than 1cm of space-occupying lesions in the liver, which was consistent with the results of the surgical examination. The diagnosis was better than the normal enhanced CT, but it was located 1cm above the liver surface and the anal area. The following nodules are difficult to diagnose. For 31 patients, except for a few localized minor pain, no other discomfort, no spleen rupture, and abdominal bleeding. Conclusions CTSP is a sensitive method for displaying PHC; it has a differential effect on intrahepatic space-occupying lesions; moreover, CTSP is safe and can be used clinically.
