摘　　要：目的探讨上腹部磁共振对比增强三维血管成像技术(three-dimensional contrast-enhanced MR angiography,3D CE-MRA),对显示门脉高压所致血管改变及血流改变的应用价值。方法对60例门脉高压患者,运用GE Signa1.5T超导磁共振扫描仪进行3D CE-MRA和2D CE-MRA成像,分析门脉高压的MRA表现。结果(1)门静脉纤细狭窄18例。(2)门静脉闭塞、海绵样变11例。(3)食管下段、胃底静脉曲张43例。(4)腔静脉狭窄、闭塞11例。(5)奇静脉、半奇静脉开放4例。(6)脐静脉开放4例。结论3D CE-MRA是诊断门脉高压所致门脉系统血管及血流改变的可靠方法。Objective To investigate the applied value of 3D dynamic contrast -enhanced magnetic resonance angiography（3D CE - MRA） ,in evaluating the portal venous system and blood flow changes in portal hypertension. Methods Sixty patients with portal hyperten- sion underwent 3D MRA and 2D - MRA of the portal venous system examinations using GE 1.5T twin speed MR machine and the MRA images were analyzed retrospectively. Results MRA images showed portal venous system with narrow and slender in 18 cases, obstruction and cavernous transformation in 11 ,case esophageal varices in 43, narrowing and obstruction of the inferior vena cava in 11 cases, azygos vein and hemiazygos vein in 4 and umbilical vein in 4 opened. Conclusion 3D - MRA is quite accurate in evaluating portal venous system and blood flow changes of portal hypertension.
