Microstructural abnormalities of the posterior thalamic radiation and the mediodorsal thalamic nuclei in females with anorexia nervosa – A voxel based diffusion tensor imaging (DTI) study
2012
Abstract Gray matter abnormalities have been found in anorexia nervosa (AN) in several brain regions. However, little is known about white matter abnormalities under the condition of AN. To comprehensively assess the microstructural integrity of white matter pathways in women with anorexia nervosa, we performed voxel-based Diffusion Tensor Imaging (DTI). 21 women with AN according to DSM-IV criteria (9 of them recovered) and 20 female age-matched healthy control subjects were enrolled in the study. The patients had a mean body mass index of 17.2 kg/m 2 (controls: 19.6 kg/m 2 ). High resolution T1 images (MP-RAGE) and DTI were performed on a 3 T Siemens-scanner. Images were pre-processed and analyzed using a modified protocol for DTI in SPM2. Fractional anisotropy (FA) maps were compared using t -tests ( p
