Fig. 6.
Noise properties of SENSE, 2D MUSE and 3D-MB-MUSE. As highlighted by red arrows both within the brain and in space, edge and central slice images of 3D ms-EPI data reconstructed by SENSE (a) and 2D MUSE (b) show elevated noise levels compared to a 3D-MB-MUSE reconstruction (c). Slice images in (a–c) scaled to 10% maximum magnitude (d–f) and g-factor maps (g–i) highlight noise amplifications (and SNR losses) both within the brain (yellow) and in space across the PE dimension (red) for SENSE and 2D MUSE that are minimized with 3D-MB-MUSE.
