This study aims to evaluate the influence of obesity on DTI findings based on the fat fraction and eigenvalues. A BMI of 25 kg/m2 was used to divide the subjects into an obesity group and a normal group. 6 ROIs on femur slices were set at the vastus lateralis, vastus intermedius, vastus medialis, biceps femoris, semitendinosus, and semimembraneous muscles. The fat fraction was higher in the obesity group than in the normal group, with significant differences for VL, BF, and SM. The all eigenvalues were low value in the obesity group, with a significant difference between groups for VL.
