目的：评价３Ｄ动态增强ＭＲ血管成像诊断腹主动脉病变的价值。方法：对３４例患有腹主动脉病变的病人进行了常规ＭＲＳＥ序列、ＣｉｎｅＭＲＡ及３ＤＣＥＭＲＡ检查，并对３种扫描方法对腹主动脉病变的显示进行了对照。结果：３２例患者中腹主动脉纡曲９例，夹层动脉瘤７例，肾动脉狭窄６例，肾动脉闭塞４例，腹主动脉瘤８例其中３例合并髂动脉瘤，全部病例３ＤＣＥＭＲＡ对血管病变的显示尤其对分支血管显示优于其它两种方法。结论：３ＤＣＥＭＲＡ在诊断腹主动脉病变方面是一项快速、准确、有效的方法。
Objective: To evaluate the value of 3D dynamic contrast-enhanced MR angiography in the diagnosis of abdominal aorta lesions. Methods: The routine MRSE sequences, CineMRA and 3DCEMRA were examined in 34 patients with abdominal aorta lesions. The contrast of the three kinds of scanning methods in the display of abdominal aorta lesions was compared. Results: Among the 32 patients, there were 9 cases of abdominal aortic aneurysm, 7 cases of dissecting aneurysm, 6 cases of renal artery stenosis, 4 cases of renal artery occlusion, 8 cases of abdominal aortic aneurysm, 3 cases of which were treated with iliac artery aneurysm. The display of the lesion is superior to the other two methods especially for the branch vessels. Conclusion: 3DCEMRA is a fast, accurate and effective method for the diagnosis of abdominal aorta lesions.
