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.
