摘　　要：目的:探讨MR血管成像及CTA对下肢动脉硬化性闭塞症动脉狭窄的诊断价值。方法:选取2016年1月至2017年12月我院收治的下肢动脉硬化患者76例,对其临床资料进行回顾性分析。全部患者均接受三维增强磁共振血管成像(3D CE-MRA)以及下肢动脉CT血管成像(CTA)检查,同时44例患者接受数字减影血管造影(DSA)检查,对各类检查方法诊断下肢动脉硬化性闭塞症动脉狭窄的价值进行比较。结果:参照DSA检查结果为金指标,在对动脉完全闭塞进行检查时,MRA的敏感度为100. 0%,特异性为100. 0%,CTA的敏感度为97. 3%,特异性为99. 1%;当动脉管腔狭窄程度达到中度以上时,MRA的敏感度为97. 9%,特异性为96. 4%,CTA的敏感度为99. 3%,特异性为97. 6%;当动脉管腔的狭窄程度达到中度以上时,MRA显示狭窄程度比CTA更为严重。结论:在对下肢动脉硬化性闭塞症动脉狭窄进行诊断时,MR血管成像及CTA均为有效方法。Objective: To investigate the diagnosis value of MR angiography and CTA for lower extremity arteriosclerotic occlusive disease with arteriarctia patients. Methods: 76 casea of lower extremity arteriosclerosis patients were selected in our hospital from Jan 2016 to Dec 2017,retrospectively analyse the clinical data of the patients. All patients were accepted three-dimensional enhanced magnetic resonance angiography( 3 D CE-MRA) and the ifextremity CT angiography( CTA) examination,and 44 patients were given the digital subtraction angiography( DSA) examination,compare the diagnosis value for different methods in the diagnosis of lower extremity arteriosclerotic occlusive with disease arterial patients.Results: DSA result as the gold standard,in the diagnosis of lower extremity complete occlusion,the sensitivity of MRA was 100%,the specificity was 100%,the sensitivity of CTA was 97. 3%,the specificity was 99. 1%; when the arterial lumen stenosis degree reached more than moderate,the sensitivity of MRA was 97. 9%,the specificity was 96. 4%,the sensitivity of CTA was 99. 3%,the specificity was 97. 6%; when the arterial lumen stenosis degree reached more than moderate,stenosis degree of MRA displayed more serious than CTA. Conclusion: In the diagnosis of lower extremity arteriosclerotic occlusive disease with arteriarctia patients,MR angiography and CTA both are the effective methods.
