In
this study, we used multi-shell diffusion-weighted imaging in an animal model
of Chronic Kidney Disease (CKD). We
focus on the functional changes in the kidney using diffusion tensor imaging
(DTI) and q-space imaging (QSI). Four Wistar
rats received surgical procedure to induce ischemic fibrosis in their left
kidney. The multi-shell
diffusion-weighted imaging was performed on the acute stage, day 2 after the
surgery. In the acute stage, the renal
medulla showed significant decrease in overall diffusivity measured by DTI and increase
in tissue restriction measured by q-space imaging.
