In DWI, common information from other diffusion
direction can be shared to increase the image quality of
one diffusion direction. However, inappropriate
selection of complementary information may provide
suboptimal image results. In this study, we
systematically compared the performance of common
information enhanced reconstruction when different
direction numbers are used for the image calculation.
Results show that care should be taken when including
other directions for one direction reconstruction in
multiple direction DWI or high angular diffusion
imaging.
