BOLD-MRI measured T2* value compared with ASL-MRI measured RBF value in kidneys of HVs and patients grouped by CKD stages into cortical and medullary. BOLD-MRI: blood oxygen level-dependent magnetic resonance imaging; ASL-MRI: arterial spin labeling magnetic resonance imaging; RBF: renal blood flow; CKD: chronic kidney disease; HVs: healthy volunteers.
