Abstract
To assess myocardial perfusion, intra-aortic digital subtraction angiography (IADSA) was performed. Functional images are generated by taking a series of myocardial enhancement images. For each pixel, maximum density of enhancement (Cmax), integrated enhancement area under the curve (Cinteg), mean transit time (MTT) and Cmax/MTT or Cinteg/MTT were extracted. DSA was applicable for evaluating myocardial perfusion in patients with ischemic heart disease.
摘要
为评估心肌灌注，进行了主动脉内数字减影血管造影（IADSA）。通过采集一系列心肌增强图像生成功能图像。对于每个像素，提取增强的最大密度（Cmax）、曲线下积分增强面积（Cinteg）、平均通过时间（MTT）以及Cmax/MTT或Cinteg/MTT。DSA适用于评估缺血性心脏病患者的心肌灌注。
