下肢外周血管疾病诊断DSA和MRA(MobiTrack)的应用及选择

The Application and Selection between DSA and MRA (MobiTrack) in Vascular Diseases of Lower Extremities

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 。

Objective To compare the effect of DSA and MRA,and explore the diagnosis methods in peripheral vascular diseases. Methods The 15 patients with vascular diseases of the lower limbs underwent DSA in which 9 patients underwent both peripheral MRA with 3D contrast\|Enhanced moving\|Bed infusion\|Tracking. Results All 9 patients were imaged succesfully with MRA,the 9 images of vascular diseases showed with MobiTrack,which were in concordance with the results found with DSA.Both venous and arteries angiography can be performed with MRA using a sigle\|injection without any side effects. Conclusion It was presented that MRA (MobiTrack) is primary choice in peripheral vascular diseases of lower limber. [
