摘要 目的对比分析CT血管造影(CTA)和磁共振血管造影(MRA)两种方法在诊断冠状动脉狭窄的优缺点对比,探讨非侵入性的检查方式临床上使用的可行性及意义。方法将我院从2011年7月至2012年4月心血管内科收治的有冠状动脉狭窄的患者42例,对患者同时作CTA、MRA两种非侵入性的检查,按照AHA9段法评价冠状动脉显影情况进行分析。结果 26例患者顺利完成MRA检查,显示冠状动脉节段共186个。冠状动脉近段、中段显影良好,与CTA比较无明显差(P>0.05),两组图像在狭窄段长度比较中差异无统计学意义(P>0.05)。MRA16例狭窄程度>50%,CTA显示14例。狭窄程度比较,对比有意义(P<0.05)。结论 MRA对狭窄的评估可靠,可作为检查冠状动脉狭窄的一种可靠筛选手段。
