摘要

目的：探讨磁共振对比增强血管三维成像（3D CE-MRA）在主动脉病变中的临床价值。材料和方法：使用1.5T高场强磁共振检查仪，对50例疑主动脉病变患者进行主动脉3D CE-MRA检查。将获得的3D CE-MRA原始数据进行减影、最大信号强度投影（MIP）、多平面重建（MPR）及表面覆盖法（SSD）等后处理技术。结果：50例中正常11例，异常39例，分别为胸、腹主动脉瘤各4例，夹层动脉瘤15例，主动脉粥样硬化13例，大动脉炎1例，主动脉变异2例。其中34经手术和/或DSA检查证实。结论：3D CE-MRA是一种无创性检查主动脉病变的可靠方法，在临床诊断和治疗主动脉病变中起到重要作用。

Abstract

Objective: To evaluate the clinical value of three-dimensional contrast-enhanced MR angiography(3D CE-MRA) in the diseases of aorta. Methods: 3D CE-MRA were performed in 50 patients with 1.5T super conductive MR scanner. Postprocessing techniques including original digital subtraction and maximum intensity projection(MIP) and multiplanar reconstrution(MPR) and surface shading display （SSD）. Results: In the 50 cases, 11 cases are normal, 39 cases are abnormal, including thoracic aortic aneurysms in 4 cases, abdominal aortic aneurysms in 4 cases, aortic dissections in 15 cases, aorta atherosclerosis in 13 cases, arteritis in 1 case, aorta aberrance in 2 cases. Thirty-four cases were proved by surgery and/or DSA. Conclusion: 3D CE-MRA is a reliable noninvasive method for examining the diseases of the aorta. It has an important role in diagnosing and treating the diseases of aorta.
