BOLD MRI may be used for detecting myocardial oxygenation changes secondary to coronary artery stenosis (1-3). Under pharmacological stress, the myocardial bed supplied by the stenotic coronary artery appears hypointense relative to healthy regions in BOLD images. Manual windowing (to visualize signal changes) and segmentation according to the American Heart Association’s (AHA) recommendation are often used to characterize the BOLD effect. However, current approaches for analyzing BOLD changes… Expand
