[…] FDG-PET images were spatially normalized to a standard template provided by SPM2 (Statistical Parametric Mapping 2, Institute of Neurology, University of London, UK) on MATLAB (version 7.1; Mathworks, Natick, MA). A local optimization of the 12 parameters of an affine transformation was applied to spatial normalization. These images were then smoothed with a Gaussian kernel (full-width at half-maximum = 16 mm) to minimize noise and improve between-subject spatial alignment. Appropriate voxel-by-voxel statistical tests were used to evaluate differences in glucose metabolism. A correlation analysis was performed to extract regions whose changes in regional cerebral metabolism correlated significantly with part A and part B of the CPT as well as scorable neuropsychological tests and MMSE, controlling for age, education and sex. Anatomical labeling of significant clusters was performed using automated anatomical labeling SPM toolbox, which was based on anatomy provided by the Montreal Neurological Institute. […]
