Wh = global left ventricular myocardium; Isc = myocardial territory subtended by significant coronary stenosis; Rem = myocardium subtended by coronary arteries with minimal or no disease; RCA = repeatability coefficient absolute; R% = repeatability coefficient % of mean.
Group means for rest and Dob at t = 0 and t = 24 demonstrate between-subject variability (bias). Mean difference and SD of values demonstrate within-subject variability (reproducibility).
