This is an interventional, multicenter, prospective study involving healthy volunteers, to primarily assess the reproducibility of multiparametric renal MRI on 1.5T scanners. The study is also aimed at assessing possible differences in renal MRI reproducibility on 1.5T MRI scanners by sex and age, and assessing possible differences in renal MRI reproducibility across field strengths (1.5T vs 3T) in the subgroup of subjects enrolled in both RESPECT clinical study and in the current subproject.
