Decreased FA observed in bilateral anterior corona radiata, superior corona radiata, sagittal stratum, and external capsule. ADC was greater in the right sagittal stratum and left superior corona radiata.
Decreased FA observed in superior longitudinal fasciculus R, corticospinal tract R, cingulum (cingulate gyrus) R, cingulum (hippocampus) R, white matter optic radiation R, and inferior longitudinal fasciculus R. No other diffusion index (MD, RD, or AD) difference was found.
No differences were found in FA, MD, AD, and RD between groups.
aThe overweight group with BMI between 25.0 and 29.9 had 96 members; the obese group with BMI ≥30.0 had 52 members. AD: axial diffusivity; ADC: apparent diffusion coefficient; BMI: body mass index; FA: fractional anisotropy; L: left; MD: mean diffusivity; N/A: not available; OB, obese; OW, overweight; R: right; RD: radial diffusivity.
