摘　　要：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 3D Dynamic Contrast enhanced MR Angiography(3D CEMRA) for abdominal aortic diseases.Methods:34 patients with abdominal aortic diseases underwent MR examination, including conventional MR SE sequence, Cine MRA and 3D CEMRA, and compared 3D CEMRA with another two imaging modalities.Results:Among the 32 cases of abdominal aortic diseases, there were 9 cases of aortic tortuosity and ectasia, 7 cases of aortic dissection, 6 cases of renal arterial stenosis, 4 cases of renal arterial occlusion, 8 cases of aortic aneurysms and 3 cases associated with iliac aneurysms.3D CEMRA superior to SE sequence and Cine MRA in demonstrating the aortic diseases, especially in depicting the branches of the aorta in all the patients.Conclusion:3D CEMRA is a rapid, accurate and useful method in diagnosing abdominal aortic diseases.
