Post hoc correlation matrix. Post hoc correlation matrix for combined patient groups of clinical factors (MAP, eFF and eGFR) and multiparametric MRI measures showing absolute correlation (R) and the associated significance (P). eFF calculated as eGFRCreatinine/(TRBFPhase Contrast × (1 − Hematocrit)). Selected significant correlations of clinical factors and multiparametric MRI measures are shown in Additional file 1. MAP mean arterial pressure, PEEP positive end-expiratory pressure, eFF estimated filtration fraction, eGFR estimated glomerular filtration rate, R2* BOLD relaxation rate, ADC apparent diffusion coefficient, T2 transverse relaxation time, T1 longitudinal relaxation time, TRBF total renal blood flow
