Synopsis

Keywords: Kidney, Transplantation

A multiparametric MRI protocol (perfusion, diffusion and T1) was employed to assess longitudinally the kidney allograft at different time points after the transplatation (first week, 3rd month and one year after the surgery) in a 3T system. Patients were divided into stable and unstable function according to their evolution.

Results showed that GFR and RBF increased for patients with stable function and decreased for patients with unstable function, showing significant differences between groups at Exam 3.

In conclusion, multiparametric MRI can help to assess the allograft longitudinally and has the potential to predict allograft dysfunction when ASL measurements are included.
