The purpose of this study is to evaluate the effectiveness of 3D PASL and 3D pCASL in assessing RBF in both the renal cortex and medulla of CKD patients and healthy volunteers. The results showed that RBF maps derived from 3D pCASL had significantly better image quality than RBF maps derived from 3D PASL. 3D pCASL has the potential to become a novel non-invasive and non-contrast MRI technique to assess renal cortical and medullary perfusion.
