Conbventional clinical indicators of kidney disease such as serum creatinine and albuminuria lack the sensitivity and specificity to identify early-stage diabetic nephropathy (DN). In this study, kidney fractional anisotropy (FA) assessments were obtained for groups of early-stage (eGFR ≥ 60) and late-stage (eGFR < 60) human subjects with diabetes for comparison with non-diabetic controls. Despite no differences in eGFR, significant differences in medullary FA (P = 0.001) were observed between control and early-stage diabetic kidneys. Further studies are needed to determine if diffusion FA could identify diabetics at risk for progression to clinically overt DN.
