Summary of in-vivo myocardial blood flow (MBF) values. a Grouped comparison of mean MBF ± standard deviation and (b) intra-volunteer variation across sectors within 10 volunteers. Two out of the three acquisition types (10× 3D k-t PCA, 10× 3D k-t SPARSE-SENSE, 2D R = 1) were performed in each volunteer. For 3D vs. 2D comparisons, a mid-ventricular region of the 3D volume corresponding to the 2D imaging slice was additionally evaluated, indicated by (slice). Intra-volunteer MBF variation was lower in fully sampled cases than in accelerated CMR, and lower in k-t PCA than in k-t SPARSE-SENSE
