Overview of image acquisition and analysis protocol. Localizer and cine images are initially acquired to allow slice planning for perfusion imaging. Pre-contrast T1 mapping and first-pass perfusion imaging is performed at stress and rest with a minimum interval of 10 minutes. The low-resolution 3-chamber slice is acquired during systole and is followed by three high-resolution short-axis slices within each RR interval. Following normalization of images, the arterial input functions are manually derived from the low-resolution slice and myocardial blood flow (MBF) is quantified for each of the 5 locations at the pixel and segmental levels. The procedure shown is performed for both stress and rest perfusion imaging to estimate myocardial perfusion reserve. aLV apical left ventricular level, AoR aortic root, bLV basal left ventricular level, LA left atrium, MBF myocardial blood flow, mLV mid left ventricular level, ROI region of interest
