To the best of our knowledge, cross-validation between ASL and DCE remains absent for the kidneys. In the present study, we examined the compatibility of ASL and DCE at the field strength of 3T by measuring renal blood flow with both techniques on a sample of healthy volunteers and one patient with renal artery stenosis. Correlation was found between ASL and DCE measurements (r = 0.9, p < 0.005). Both ASL and DCE were able to distinguish the reduced RBF in the patient with renal artery stenosis. We conclude that ASL and DCE provide compatible measurement of renal perfusion at 3T.
