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.
