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.
