Classification of anatomical renal structures in
diffusion-weighted echo-planar images may be difficult
to perform. For this reason a simple transfer of
segmented areas from high-resolution FSE/GRE images with
suitable visualization of the anatomy to DTI images
would be helpful but is hampered by geometric
distortions. The purpose of this study was to assess the
feasibility of renal segmentation and their internal
structures in distortion corrected DTI images. Six
volunteers were examined at 3T. It was found that DTI
values can be accurately determined in specific areas of
distortion corrected images by manual renal segmentation
in corresponding high-resolution anatomical images.
