Renal functional MR imaging of Patient A with LN-IV(S)A. (a) DWI imaging. (b) T2* imaging. The proteinuria was 1.3 g/24 h and serum creatinine was 52 mol/L, the renal pathology AI was 12 and CI was 0. Renal BOLD images showed a clear demarcation between cortex and medulla. The ADC value of left kidney was 2.81 x10^-3 mm²/s and that of right kidney was 2.78 x10^-3 mm²/s, the R2* values were similar to normal kidneys.
