A newly developed non-contrast MRI oximetry method was applied to evaluate skeletal muscle perfusion and oxygenation in individuals with diabetes mellitus. The study was performed in 4 healthy volunteers and 4 age-matched diabetic patients, at rest and during sustained isometric exercise. Significant attenuations in muscle perfusion and oxygenation were clearly observed in diabetic patients.
