A comparison of segmented, motion corrected, fully sampled images reconstructed with gridding (left) and 3D iNAVs reconstructed with ESPIRiT (right) acquired with identical isotropic spatial resolutions in two subjects. The resolution of the images are 12.7, 8.8, 6.1, 5.2, 4.4, and 3.5 mm with corresponding acceleration factors of 1, 2, 4.3, 6.2, 9.1, and 15.4 (top to bottom).
