TL;DR: The application of the brain atlas for visualization in surgical planning far model-driven segmentation and for the teaching of neuroanatomy is presented.

TL;DR: A computerized system for processing spin‐echo magnetic resonance (MR) imaging data was implemented to estimate whole brain and cerebrospinal fluid volumes and to display three‐dimensional surface reconstructions of specified tissue classes, showing good reliability for the automated segmentation procedures.

TL;DR: At least in this group of schizophrenic subjects with mainly positive symptoms, temporal lobe abnormalities can exist in conjunction with no gross volumetric abnormalities of the prefrontal cortex.

TL;DR: MRI scans indicate abnormalities throughout all basal ganglia structures in at least a subgroup of schizophrenic patients and are associated with poorer neuropsychological test performance on finger tapping and Hebb's Recurring Digits.

TL;DR: The results demonstrate that this computerized procedure allows routine reproducible quantitative analysis of large serial MRI data sets and was superior to that of supervised segmentation, as evidenced by the coefficient of variation.
