| 摘 要： | 目的：比较64层MSCT冠状动脉CTA检查时心肌低密度与增强MRI延迟强化对心肌梗死体积显示的差异。材料和方法：回顾性测量同时行64层MSCT和DE-MRI检查的心肌梗死患者23例。64层MSCT冠状动脉CTA图像进行左室短轴位图像重建，层厚8mm，层间隔8mm。测量每层短轴位图像上心肌低密度面积，将各层低密度面积累计积分得到体积。上述患者行DE-MRI延迟扫描，左室短轴位层厚为8mm，层间隔8mm，将各层中延迟强化心肌面积进行累计积分，得到MRI延迟强化测量的心肌梗死体积。将上述两种方法测量的体积进行配对t检验，以DE-MRI延迟强化得到的体积做为参考标准，比较MSCT通过心肌低密度判断心肌梗死的准确性。结果：64层MSCT冠状动脉CTA图像低密度与DE-MRI延迟强化测量得到的体积分别为（7.66±5.95）ml和（15.33±9.71）ml，P<0.01，二者相关系数为0.727。结论：通过64层MSCT冠状动脉CTA显示心肌低密度判断心肌梗死与DE-MRI有一定相关性，但会低估梗死的范围。

| Abstract: | Objective:To assess myocardial hypo-enhancement in demonstrating the myocardial infarction (MI) in coronary artery CT angiography(CTA) performed by 64-MSCT and to compare the results with delayed-enhanced MRI(DE-MRI). Materials and Methods:Twenty-three patients suspected of MI underwent both 64-MSCT and DE-MRI scanning. On 64-MSCT scanning, 60~85ml iodine contrast medium(370mgI/ml) were injected and flushed with 40ml saline, injection velocity is 4~5ml/ s. The short axis of the left ventricle was reconstruc... |
