Reproducibility of multiparametric MRI (perfusion, diffusion and T1 mapping) was assessed in renal allograft
Figure 1: Example of multiparametric MRI maps acquired during
the two MRI exams: arterial spin labeling perfusion maps, diffusion coefficient
(D) maps, pseudo-diffusion coefficient (D*) maps, perfusion fraction maps
and longitudinal relaxation (T1) maps.
Figure 2: a) Bland-Almant plots for the RBF (ml/min/100g), D (×10−3 mm2/s), D* (×10−3 mm2/s), PF (%) and T1 (ms) calculated in the cortex and in the medulla. b) Correlation between cortical mean values of renal blood flow and perfusion fraction averaged for the two exams, with a correlation coefficient r = 0.47.
