目的：探讨螺旋ＣＴ动脉门脉造影（ＳＣＴＡＰ）三维成像显示肝内占位病变门脉改变的价值。材料与方法：２０例经病理证实或临床综合诊断原发性肝癌１５例，转移性肝癌４例，肝结核１例，均经肠系膜上动脉或脾动脉置导管行ＳＣＴＡＰ。结果：ＳＣＴＡＰ三维成像的门脉显示质量优于间接门脉ＤＳＡ，能清楚显示门脉４～５级分支，显示门脉远端分支破坏、中断优于ＳＣＴＡＰ轴位像，但肝癌门脉小分支瘤栓形成的显示较ＳＣＴＡＰ轴位像差。结论：ＳＣＴＡＰ扫描时间根据间接门脉ＤＳＡ门脉显影时间确定为佳。ＳＣＴＡＰ三维成像门脉显示优于间接门脉ＤＳＡ，结合ＣＴＡＰ轴位像能判断门脉分支病变，对肝内占位病变的鉴别诊断有一定价值。
Objective: To investigate the value of spiral CT angiography (SCTAP) three-dimensional imaging of intrahepatic space-occupying lesions portal vein. Materials and Methods: Twenty cases of pathologically confirmed or primary primary liver cancer diagnosed in 15 cases, 4 cases of metastatic liver cancer, 1 case of liver tuberculosis, by the superior mesenteric artery or splenic artery catheter SCTAP. Results: SCTAP three-dimensional imaging of the portal vein display quality is better than indirect portal venous DSA, can clearly show the portal vein grade 4 to 5, showing that the distal portal vein rupture, interruption is better than the S CTCT axial imaging, but liver cancer Small portal vein thrombosis showed SCTAP axial aberration. Conclusion: The time of SCTAP scanning is better than that of DSA portal vein imaging. SCTAP three-dimensional imaging portography is superior to indirect portal venous DSA, combined with CTAP axial imaging can determine portal disease, the differential diagnosis of intrahepatic space-occupying lesions of some value.
