摘　　要：目的：探讨动态增强磁共振血管造影(dynamic contrast enhanced MR angiography,DCE MRA)在胸腹部大血管疾病中的应用价值。材料与方法：对24例患有胸腹主动脉病变的病人进行了常规MR SE序列、2D-BOLUSTRAK及3D CEMBA检查,并对3D CEMRA扫描方法对胸腹主动脉病变的显示进行分析。造影剂注射速度和扫描时间依据靶血管的性质、部位、范围而定。结果：24例中14例主动脉瘤,6例动脉粥样硬化,2例髂血管闭塞症,2例肾动脉狭窄,全部病例3D CEMRA对血管病变的显示尤其对分支血管显示效果佳。结论：3D CEMRA在诊断胸腹主动脉病变方面是一项快速、准确。Purpose： To study the application of dynamic contrast enhanced MR angiography （DCE MRA） in diagnosing the lesions of larger chest and abdomen vessels. Materials and Methods： 24 patients with pectoral and abdominal aortic diseases underwent MR examination, including conventional MR SE sequence, 2D- BOLUSTRAK and compared 3D CEMRA with analyse imaging modalities of 3D CEMRA in pectoral and abdominal aortic diseases, The injection rateandac quisifion time were determined on the basis d location and features d the target vessels. Results： Among the 24 cases of pectoral and abdominal aortic diseases, there were 14 cases of aortic aneurysms, 6 cases cinhosis of aorta, 2 cases of common iliac arterial occlusion, 2 cases of renal arterial stenosis, 2 cases of renal arterial occlusion, 2D CE MRA superior image in the aortic diseases, especially in depicting the branches of the aorta in all the patients. Conclusion： 3D CEMBA is a rpaid , accurate and useful method in diagnosing pectoral and abdominal aortic diseases.
