Summary of experiments per MRI acquisition

MRI acquisition	Applied and optimized	Protocolled experiments	Summary results
T2‐weighted imaging	Porcine n = 22 Human n = 4	Induced ischemia‐reperfusion (duration 30–90 min) Porcine n = 6 Iron oxide labeled MSCs Porcine n = 1	During ischemia, the T2 signal notably decreased and after reperfusion, it took up to 30 min for this signal to recover to its initial value. MSCs were inhomogeneously deposited within the renal cortex
T2* map	Porcine n = 22 Human n = 4	Deoxygenation 20 min Porcine n = 1	Baseline: T2* = 50.4 ms 5 min stop O2: T2* = 46.2 ms 10 min stop O2: T2* = 47.8 ms 20 min stop O2: T2* = 27.8 ms 5 min restart O2: T2* = 45.3 ms
ASL	Porcine n = 13	Perfusion maps first 3 h Porcine n = 9 Human n = 4	Corticomedullar ratio at 30, 60, 120, and 180 min Porcine: 2.1, 5.0, 6.5 and 5.3 Human: 1.2, 3.0, 4.5 and 6.6
Spectroscopy	n.a.	Hyperpolarized [1‐13C]pyruvate Porcine n = 4	13C‐lactate concentrations were decreased in the cortex compared with the medullar regions

Abbreviations: ASL, arterial spin labeling; MRI, magnetic resonance imaging; MSCs, mesenchymal stromal cells.
