Table 2.
(a) PGSE and (b) STEAM protocols. Both come from the experiment design optimisation in 12,25 with Gmax = 300 mTm− 1. N is the number of diffusion-weighted images in each shell. K is the number of nominal b = 0 images associated with each shell. The nominal b = 0 images in STEAM have the same τm as the diffusion-weighted images. The compensated STEAM protocol STEAMCOMP follows (b), but replaces each Gd according to Equation [8]. Please refer to Figure 1 for notation
