目的 比较DSA和MRA(MobiTrack)对外周血管的成像作用 ,探讨外周血管疾病的诊断方法选择。方法 对 15例因各类病因引起的下肢外周的血管闭塞、狭窄的患者进行DSA和MRA检查。结果 MRA可无创性一次显示外周动静脉血管 ,DSA对动静脉显示需分次穿刺造影 ,对需介入治疗的部分患者需分次进行 ,9例患者MRA发现的 9处病灶与DSA结果完全相同 ,但DSA有二处显示胫前动脉二级分支的狭窄 ,MRA未见显示。结论 MRA是一种无创性动静脉成像方法 ,对外周性血管疾病应做为首选和基本检查方法
Objective To compare imaging effects of DSA and MRA (MobiTrack) on peripheral blood vessels and to explore the methods of diagnosis of peripheral vascular diseases. Methods DSA and MRA were performed in 15 patients with vascular occlusion and stenosis of lower extremity caused by various causes. Results MRA showed peripheral arteriovenous vessels non-invasively at one time. DSA showed arteriovenous and venous punctures, and some patients needed interventional therapy to be divided into several groups. MRA found 9 lesions in 9 patients and DSA exactly the same, However, there were two DSA showed stenosis of the anterior tibial artery secondary branches, MRA no show. Conclusion MRA is a noninvasive method of arteriovenous imaging. Peripheral vascular disease should be the first choice and basic examination method
