The purpose of this exhibit is to present the effects of the combinations of b-values and Rician noise filter for DTI and DKI metrics in the spinal cord, for clinical use in particular. The different combinations of b values result in the different diffusion metrics, such as mean kurtosis. Therefore, suitable selection of b values is important for the specific purpose of the study. Moreover, Rician denoising technique lead to appropriate DKI and DTI metrics estimation, mean kurtosis in particular because the diffusion MR images of spinal cord often suffer from low signal-to-noise ratio in vivo.
