The
aim of this study is to investigate if DTI can be used for imaging the
principal route of free water in the kidney, and we hypothesize that this route
can act as an indirect representation of the segments of nephrons going
centripetally from the renal parenchyma to the collecting ducts. The
orientation of medullary diffusion anisotrophy was visualized using a
proposed DTI tractography method
