Three sets of data were named depending on their origin and MRI acquisition protocol as: Leiden-Set, Cologne-Set-1 and Cologne-Set-2, respectively. Animals of different strains and ages were scanned at different time points after the infarct induction using different magnetic field strength and different MRI acquisition parameters. In total, 121 T2 scans (not counting the brain scan used as template) and 99 diffusion scans were made available.
