摘要
目的 探讨冠状动脉狭窄或闭塞在磁共振心肌灌注成像中的表现。方法 28例缺血性心脏病患者行磁共振心肌灌注成像检查,对其表现及诊断价值进行研究。结果 19例(67.9%)首过期出现灌注异常,其中17例(89.5%)为冠状动脉多支病变。19例磁共振心肌灌注成像异常中分别灌注减低8例(42.1%),其中局限1个壁段2例,2个壁段2例,3个以上壁段4例;灌注缺损11例(57.9%),其中局限1个壁段2例,2个壁段4例,3个以上壁段5例。注入GD-DTPA对比剂后延迟扫描,8例(42.1%)显示心肌增强,其中局限1个壁段2例(25%),2个壁段3例(37.5%),3个以上壁段3例(37.5%)。 结论 磁共振心肌灌注成像能识别心肌的缺血与梗死,可以指导临床制定治疗计划,判断治疗效果和进行预后的评价。
Objective To study the manifestations of magnetic resonancemyocardial perfusion imaging (MRMPI) in coronary artery stenosis or occlusion.Methods MRMPI were performed in 28 patients with ischemic heart disease,which were confirmed by clinic and coronary angiography.The manifestationsand value of diagnosis of MRMPI were studied. Results Of 19 cases therewere 8 cases of perfusion decreasing (42.1%).2 cases located in 1 myocardialsegment,2 cases in 2 myocardial segments,4 cases in over 3 myocardialsegments.There were 11 cases of perfusion defect (57.9%).2 cases located in1 myocardial segment,4 cases in 2 myocardial segments,5 cases in over 3myocardial segments.In delayed MRMPI with GD-DTPA,8 cases were en-hanced(42.1%).2 cases located in 1 myocardial segment (25%),3 cases in 2myocardial segments (37.5%),3 cases in over 3 myocardial segments (37.5%).Conclusion MRMPI can recognize the ischemia or infarction of the myocardium.MRMPI is very important to make the plan of treatment,judge the effect oftreatment and evaluate the prognosis.[
