Influence of framerate and pSAT angle on the proposed pSAT sequence measured in healthy subjects. Data are shown as average and standard deviation over all subjects. Low pSAT angles (<20°) resulted in reduced balloon/blood CNR, while high pSAT angles (>40°) led to reduced blood and myocardium SNR. In this pSAT range of interest (20° to 40°), lower framerate resulted in higher balloon, blood, and myocardium SNR, but reduced balloon/blood CNR and balloon/myocardium CNR
