摘要
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 inquire into the application value of threedimensional reconstrution spiralCT arterial portography (3DSCTAP) in liver occupying diseases.Materials and Methods:20 patients were examed by 3DSCTAP. 15 patients were primary hepatic carcinoma, 4 patients were liver metastatic carcinoma and 1 patient were tuberculosis of liver confirmed by operation and pathology.Results:3DSCTAP image showed the 4~5 grades branches of portal vein (100%). The display rate of destruction and deviation of distal PV branches in 3DSCTAP was higher than transversal image of SCTAP, but display rate of tumor thrombi within PV branches was lower than transversal image of SCTAP.Conclusion: 3DSCTAP with transversal image of SCTAP can provide reliable evidence for pathological changes of PV. 3DSCTAP is helpful to differential diagnosis of liver occupying diseases.
