Multiband imaging allows for greater imaging speeds when collecting diffusion weighted MR images. As shown in this work, this saving in time results in small changes in several stages of diffusion image processing including tensor fitting and the associated calculation of scalar values such as FA, fiber orientation distribution calculation as in constrained spherical deconvolution, and tractography.
