Optimal Short-Time Acquisition Schemes in High Angular Resolution Diffusion-Weighted Imaging

The effect of the -value and the number of gradients at . At higher -values we observe many spurious peaks that disappear with the increase of the number of gradients (see yellow marked rectangles). At there is not a significant difference between the profiles at s/mm2 and s/mm2. Given that the spurious peaks are slightly more prominent at s/mm2, and that lower -values are more attractive with respect to the total scanning time, we conclude that s/mm2 and are the optimal combination of parameters.
