[Assessment of myocardial perfusion using digital subtraction angiography].
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.
