| 摘 要： | 目的:探讨多层螺旋CT门静脉造影(MSCTP) 的成像方法及其临床应用价值.材料和方法:110例临床推荐行腹部增强扫描的患者.运用最大密度投影(MIP)和容积重建(VR)两种后处理成像方法,10例增加曲面重建(CPR).结果:MSCTP能很好显示肝静脉和门静脉系统的全貌及其与病变之间的空间解剖关系,直观地评价门静脉的位置、轮廓、有无门静脉受侵或癌栓形成, 了解门静脉高压侧支循环的分布范围和程度.结论:MSCTP是肝静脉和门静脉无创性检查的可靠方法, 有较高的临床应用价值.VR比MIP重建的血管图像更优.

| Abstract: | Purpose: To evaluate the techniques and clinical applications of multi slice helical CT portography(MSCTP). Materials and Methods:110 patients recommended to abdominal enhancement scan were selected. All patients were reconstructed in the mode of maxium intensity projection (MIP) and volume rendering (VR) ,and curved planar reformation(CPR) was added in 10 patients. Results: MSCTP image could directly demonstrate the location and width of the portal and hepatic veins, detect the invasion and tumor thrombosis of portal vein, and show the range of collateral circulation and estimate its degree in portal venous hypertension. Conclusion: As a non-invasive and reliable method, MSCTP has high clinical application values in the evaluation of portal venous and hepatic venous system. Reconstruction images of VR are better than that of MIP. |
