Alterations in cortical surface morphometry in fibromyalgia: a multi-parametric study
Changan Sun
IntroductionFibromyalgia (FM) is a chronic pain disorder with unclear neuroanatomical basis, as previous studies largely relied on volumetric measures insensitive to cortical surface morphology. This multi-parametric surface-based morphometry study examined cortical thickness (CT), fractal dimension (FD), gyrification index (GI), and sulcal depth (SD) in FM.MethodsThirty-three female FM patients and thirty-three age-matched female healthy controls (HC) underwent T1-weighted MRI.
