Diffusion-weighted imaging data were acquired using at multiple b-values and motion corrected with MCMB (motion correction of multi b-value). The repeatedly acquired low-b-value images were used to prospectively detect and correct for displacement during extended acquisitions. Co-registration of higher b-value images was achieved by nearest-neighbor interpolation of transformation parameters estimated at lower b-values.
