Acquisition of diffusion spectral imaging data involves long scan times. One way of reducing the scan time is by minimizing the number of q-space points based on its symmetry. In this study we have adapted a tracking procedure and compared the fiber pathways generated from three subsample data sets to the fully sampled q-space data set. For both fornix and cingulum fiber bundles, qualitatively and quantitatively the 198 subsample data set with angles of threshold between 41 and 45 degrees have shown a result that are close to the full data set. This reduces the scan time by 11 minute.
