Dear all, we acquired mprage images of a Siemens tim-Trio scanner and converted the DICOMs into nifti-Format for VBM and manual Morphometry. Nifti images were automatically co-registered with the MNI Standard brain in SPM8 by changing the header information. No reslicing was performed. We noticed differences in volumes in the aseg_stats_tables depending on the initial orientation of the individual brain. Is there a standard procedure to optimally reorient the images before processing the recon-all analysis? Is it better to use reoriented images that have been resliced or is it sufficient to change only the header information? Is it advisable to reorient the anatomical images manually to AC-PC before running recon-all?
