本研究经伦理委员会同意认可,并签署书面同意书。本研究目的是评价多回波T2*mapping发现急性心肌梗死后行经皮冠状动脉介入术后再灌注出血的可能性。并用T2WI检测出血对定量测量缺血风险区域的影响。15例病人(男13例,女2例;平均年龄59岁)在行冠状动脉介入治疗平均3.2d后行MRI扫描。平均出血区域,由少于20ms的T2衰减常数显示有(5.0±4.9)%梗死程度。
The research was endorsed by the Ethics Committee and written consent was signed. The aim of this study was to evaluate the potential of multiple echo T2 * mapping to detect reperfusion bleeds following percutaneous coronary intervention following acute myocardial infarction. The effect of hemorrhage on quantitative measurement of ischemic risk area was also examined by T2WI. Fifteen patients (13 males and 2 females; mean age 59 years) underwent MRI scanning after an average of 3.2 days of coronary intervention. In the mean hemorrhage region, the degree of infarction was (5.0 ± 4.9)% with T2 decay constants less than 20 ms.
