  1. Abbreviations: CG control group; DN diabetic nephropathy.
  2. Values are means ± standard deviation.
  3. *P < 0.05 vs. the control group.
  4. There were no significant differences in the R2* values between the type 1 and type 2 diabetic nephropathy groups in the same renal compartment at the same time.
