Quantitative MRI Demonstrates Abnormality of the Fornix and Cingulum in Multiple Sclerosis
Mean MRI indices in MS cases and healthy volunteers across the fornix (a) and averaged cingula (b), left cingulum (c) and right cingulum (d). *Indicate significant differences between the two groups. FA: fractional anisotropy, MD: mean diffusivity, and MTR: magnetization transfer ratio. Error bars represent the standard deviations of the measures.
