Purpose: to evaluate the prognostic potential of a multiparametric renal MRI protocol (perfusion, diffusion and T1) for the assessment of the allograft in the very early stages after transplantation.

Methods: 18 transplanted patients were imaged 6 days after the transplantation with ASL, IVIM and T1 mapping sequences. 2 groups were made depending on the allograft evolution (group A: no adverse events and group B: any adverse event).

Results: eGFR, album-creatinine ratio and cortical and medullary RBF were significantly higher in allografts of group A than in group B. Significant correlations between eGFR and RBF were found.
