摘　　要：目的:评价三维对比增强MRA在下肢动脉病变血管成像中的临床应用价值。方法:对56例临床疑有下肢动脉疾病的患者行三维对比增强MRA检查,同时24例行DSA检查,3例行手术治疗。结果:双下肢主干动脉满意显示1032个,显示满意率为96.9%(1032/1064)。在所显示动脉血管节段中,正常或轻度狭窄543个节段,严重狭窄382个节段,闭塞107个节段。与DSA或手术结果比较,两者诊断符合率为96%(24/25)。结论:三维对比增强MRA应用于下肢动脉病变检查,具有定位准确、无医源性损伤、安全迅速及可重复进行等优越性,是外科治疗下肢动脉疾病的重要依据,具有广阔的临床应用前景。Objective:To evaluate the clinical value of three dimensional contrast enhanced MRA(3D-CE-MRA)in the imaging of the diseased arteries in lower extremities.Methods:Fifty six patients suspected of having lower extremity arterial diseases underwent 3D contrest-enhanced MRA.Among these patients,24 cases underwent DSA examination.3 cases were detected by operation.Results:About 96.9%(1 032/1 064)arterial segments images of the main arteries of the lower extremities were achieved by 3D-CE-MRA satisfactorily.In th...
