Significant differences among the six groups were observed in cortical T1, T2*, R2*, ASL, IVIM (ADC, D), and CMD at optimal TI. Specifically, cortical T2 and CMD differed between healthy and low-risk groups; IVIM (D) and CMD between low- and medium-risk; T1 and IVIM (ADC) between high- and very-high-risk; and CMD between very-high- and highest-risk groups. No significant differences were found between the medium- and high-risk groups.

A total of 122 cases, including 23 healthy volunteers and 99 diabetic patients, were studied.
A total of 122 cases, including 23 healthy volunteers and 99 diabetic patients, were studied. Diabetic patients were classified into 5 groups; low risk group (n=27), moderate risk group (n=19), high risk group (n=12), very high risk group (n=22), and highest risk group (n=19) based on the KDIGO 2022

All subjects underwent non-contrast MRI using a 3-Tesla MRI machine. Measurements were made of the renal cortex and renal medulla T1 values, T2 values, blood oxygenation level dependent (BOLD) imaging (T2* values and R2* values), intravoxel incoherent motion (IVIM) imaging (ADC, f, D* and D values), arterial spin labeling (ASL) as well as optimal inversion time (TI) (= TI of maximum corticomedullary contrast ratio (CMR = signal intensity (SI) of cortex / SI of medulla)) and inverted TI value (value of TI that inverts the renal cortex and renal medulla SI) on steady-state free precession (SSFP) with inversion recovery (IR) pulse with multi TI (TI = 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800 msec) (Fig. 1). A total 21 parameters were compared between healthy groups and early DN group.
