## Abstract Myocardial perfusion reserve (MPR, defined as the ratio of the maximum myocardial blood flow (MBF) to the baseline) is an indicator of coronary artery disease and myocardial microvascular abnormalities. Firstβpass contrastβenhanced magnetic resonance imaging (CEβMRI) using gadolinium (G

## Abstract ## Purpose To validate a noninvasive quantitative MRI technique, the K~i~ perfusion method, for myocardial perfusion in humans using ^13^Nβammonia PET as a reference method. ## Materials and Methods Ten healthy males (64 Β± 8 years) were examined with combined PET and MRI perfusion im
The purpose of this study was to examine the feasibility of quantifying myocardial blood flow (MBF) and rate of myocardial oxygen consumption (MVO(2)) during pharmacologically induced stress without using a contrast agent. The former was measured by the arterial spin labeling (ASL) method and the la
