Figure 1

Slice acceleration up to MB factor of 12 (upper panel) demonstrates negligible image degradation up to MB = 6 and good image quality up to MB = 8. Images were acquired with matched TR = 4.8 s at 2 mm isotropic resolution (60 or 64 slices) for comparison between MB factors. The example axial slices shown here were not from the same MB slice group. Achievable TR at a given MB factor is listed below the images to show the acceleration potential. Axial, coronal, and sagittal views of MB = 8 image from a different subject at minimum TR = 0.6 s (bottom panel) illustrate the contrast alteration and SNR compromises with TR reduction.
