动态移床3DCE-MRA对糖尿病患者下肢动脉病变诊断的探讨

MR angiography of low limb artery with a moving-bed infusion-tracking technique in diabetes

目的评价动态移床3D-CE MRA 在糖尿病患者下肢动脉病变中的诊断价值。方法分析21例糖尿病患者下肢动脉的 MRA 检查结果,观察血管全貌、分支走行和狭窄的部位及范围等病变情况。比较3D-CE MRA 与 DSA 的分段符合率。结果 MRA 图像质量优者16例,质量良者5例;无图像质量差者。在10段血管中,MRA 发现动脉狭窄29处,DSA 发现36处,两者的总符合率为80.6%。两种检查诊断结果统计学兀显著性差异。结论动态移床3D CE-MRA 安全无创,对于糖尿病患者下肢动脉病变的诊断效果类似于 DSA,但更容易被患者接受。

Objective To explore the diagnostic value of MRA with a moving-bed infusion-tracking technique in lower limb arterial disease of diabetic patients. Methods MRA of low limb artery in 21 diabetes patients were analyzed. And the results were compared with that of DSA. Results 16 cases were excellent MR imaging and 5 were good. In 10 sections of low limb artery, 29 stenosis were displayed by MRA and 36 by DSA. The total accordance rate was 80.6%. There was no statistically significant difference between MRA and DSA in the diagnosis of stenosis. Conclusion MRA was a reliable method and non-invaslve method with excellent correlation between MRA and DSA in the diagnosis of arterial stenosis.
