  1. Note: CR2*, cortical R2*; MR2*, medullary R2*; ADC, apparent diffusion coefficient; CADC, cortical ADC; MADC, medullary ADC. The value of CADCl and MADCl were collected from the ADC map of low b values and the values of CADCh and MADCh were collected from the ADC map of high b values. *p < 0.05 compared with the control group; #p < 0.05 compared with the ATN group.
