Diffusion tensor imaging is emerging as a promising technique for structural and functional evaluation of the kidneys. However, diffusion sequences employing echo planar imaging readout are prone to geometric distortions due to static field inhomogeneities arising from different magnetic susceptibilities from adjacent tissues and bowel gas. In this study, we evaluated the efficacy of distortion correction using a reversed phase encoding approach for diffusion tensor imaging of healthy controls and patients with Type 1 diabetes.
