多层螺旋CT门静脉成像技术的探讨及其临床应用

Multi-slice Spiral CT Angiography of Portal Vein and Its Clinical Applications

目的：探讨多层螺旋CT门静脉成像的检查技术及其临床应用。方法：利用《中国期刊全文数据库》、维普资讯网及PubMed查阅1992～2005年有关门静脉造影方面的论著和综述，就多层螺旋CT门静脉成像的检查技术及其临床应用方面加以综述。结果：多层螺旋CT门静脉成像具有重要的临床应用价值，有利于显示肝脏分段及门静脉高压所致的静脉曲张，恶性肿瘤可切除性的评价，肝移植及TIPSS术前术后评价。结论：多层螺旋CT门静脉成像具有快速、高分辨率、三维图像多角度观察等传统血管造影法无法比拟的优势，是目前临床上广泛应用的较理想的门静脉成像技术。

Objective：To study the technique of Multi- slice spiral portal vein angiography and its clinical applications. Methods： Consulting articles and reviews about portal vein angiography from 1992 to 2005 by CNKI, CQVIP and PubMed, then reviewing the technique of Multi - slice spiral portal vein angiography and its clinical applications. Results：Multi- slice spiral portal vein angiography had important clinical value. It is advantageous to manifest liver segment and varicosis caused portal hypertension, respectable assessment of malignant tumors, evaluation before and after liver transplantation and TIPSS. Conclusion：Multi- slice spiral CT portography has many advantages such as high speed, high resolution and three - dimensional imaging which are far superior to traditional angiography , it is an clinically used ideal imaging of the portal vein.
