| 目的 探讨MR时间分辨对比剂动态增强技术(TRICKS)在诊断糖尿病足下肢动脉病变中的临床价值。方法 回顾性分析18例糖尿病足双侧下肢血管病变患者的TRICKS及DSA资料,将研究血管分为腘动脉、胫腓动脉干、胫前动脉、胫后动脉、腓动脉、足背动脉6个节段,以DSA作为标准进行分析。结果 在216个动脉节段中,187个节段两种检查显示一致,TRICKS高估21个节段,低估8个节段。TRICKS对于下肢狭窄动脉的判断平均准确率为86.57％,平均敏感度为90.98%,平均特异度为75.79%。TRICKS和DSA对血管狭窄程度分级的总符合率为86.57％。结论 TRICKS是诊断下肢血管病变的可靠方法。 |

| Objective To explore the diagnostic value of MR time-resolved imaging of contrast kinetics (TRICKS) in lower extremity arterial disease of diabetic foot. Methods The data of lower extremity arteries of 18 patients with diabetic foot acquired with TRICKS and DSA examinations were retrospectively analyzed. The arteries were divided into six segments: popliteal artery, tibiofibular artery trunk, anterior tibial artery, posterior tibial artery, peroneal artery, dorsalis pedis arteries, and were analyzed taking DSA as the standard. Results All of 216 arterial segments, 187 segments examined with TRICKS were consistent with that of DSA, but 21 segments were overestimated, 8 were underestimated. The average accuracy of TRICKS for lower extremity arterial stenosis was 86.57%, the average sensitivity was 90.98%, the average specificity was 75.79%. The total coincidence rate of TRICKS and DSA for classification of stenosis degree was 86.57%. Conclusion TRICKS is a reliable method in diagnosis of lower extremity vascular disease. |
