Echo-planar imaging (EPI) is usually applied to acquire diffusion-weighted images. While EPI is fast in acquiring an entire image, it brings along distortion artifacts. Turbo spin echo (TSE) acquisitions require more time than EPI, but avoid distortions. Purpose of this study was to compare TSE and EPI for diffusion tensor imaging of the human kidney. We found similar mean diffusivity with EPI and TSE. Fractional anisotropy provides good corticomedullary contrast with both methods TSE and EPI. TSE is a practicable alternative to EPI for diffusion tensor imaging of the kidney.
