Renal T1 and R2* mapping were performed on 55 diabetic nephropathy (DN) patients , 20 healthy volunteers（HVs）and 10 diabetes mellitus (DM) patients to explore the clinical potential in assessing renal function. While comparable T1 and R2* values of renal cortex were found between HVs and DM patients, DN patients showed significantly increased T1 and R2* values of renal cortex relative to HVs and DM patients. Both T1 and R2*metrics were also significantly correlated with renal function. Therefore, quantitative T1 and R2* mapping might be considered effective measures in evaluating renal function for DN patients.
