Myocardial perfusion measurements with first-pass perfusion MR imaging. a Signal intensity-time curve of LV cavity and myocardium derived from the mean signal intensity within regions of interest (ROI) measured in an MR image of the heart. Relative upslope was determined by dividing maximal upslope of the myocardium by maximal upslope of the LV cavity. b Semi-quantitative myocardial perfusion values (relative upslope) in LV myocardium of control rats (n = 9) and rats on HFD (n = 9) were presented during baseline conditions and adenosine infusion. Data are expressed as mean ± SEM, *p < 0.05 adenosine effect
