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.
