The purpose of this study was to develop a quantitative method for myocardial blood flow (MBF) measurement that can be used to derive accurate myocardial perfusion measurements from dynamic multidetector computed tomography (MDCT) images by using a compartment model for calculating the first-order transfer constant (K1) with correction for the capillary transit extraction fraction (E). Six canine...
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...
Background: Besides cardiac transplantation, there are few therapeutic options for patients with failing dilated atriopulmonary connections (APC). While conversion to a total cavopulmonary connection has been suggested as an option, this procedure is technically difficult and requires additional intra-atrial suture lines. We addressed the hypothesis that the use of a bidirectional superior cavopulmonary...
