This is the first MR study to evaluate the use of zoomed EPI technology for diffusion-weighted imaging in the kidney. Zoomed diffusion-weighted EPI leads to substantial image quality improvements with reduction of susceptibility artifacts in renal DWI. The combination of the two sequences for renal imaging might be recommended: a c-EPI scan to cover and screen the whole upper abdomen and a z-EPI scan focused on the targeted anatomical structure and suspected lesions.
