A ROC of FA. The cutoff values of FA of the cortex/medulla used to diagnose CKD were 0.23, 0.22, AUC is 0.828, 0.848, and accuracy is 82.9%, 80.7% respectively. B ROC of ADC. The cutoff values of ADC of the cortex/medulla used to diagnose CKD were 1.75, 1.85 × 10⁻³ mm²/s, AUC is 0.910, 0.81, and accuracy is 84.1%, 79.5% respectively
