The ZOOPPA technique provides highly resolved dMRI data at 7T, but whole-brain data sets take a long time to acquire. EPI volume acquisition time can be greatly reduced using blipped CAIPIRINHA. We have implemented combined ZOOPPA and CAIPIRINHA, enabling highly resolved and accelerated acquisition of dMRI data at 7T.
