Abstract

In this study, we used multi-detector computed tomographic (MDCT) images of human left ventricles at end-diastole and end-systole to perform quantitative analysis and comparison of heart motion in patients with anterior wall myocardial infarction and ischemic cardiomyopathy (ICM) versus those with global non-ischemic cardiomyopathy (NICM). MDCT ventricular images of 25 patients (13 with ICM) with ejection fraction (EF)
