BACKGROUND AND PURPOSE Rasmussen syndrome, also known as Rasmussen encephalitis, is typically associated with volume loss of the affected hemisphere of the brain. Our aim was to apply automated quantitative volumetric MR imaging analyses to patients diagnosed with Rasmussen encephalitis, to determine the predictive value of lobar volumetric measures and to assess regional atrophy differences as...
Background: Accurate brain tissue segmentation from magnetic resonance (MR) images is an important step in analysis of cerebral images. There are software packages which are used for brain segmentation. These packages usually contain a set of skull stripping, intensity non-uniformity (bias) correction and segmentation routines. Thus, assessment of the quality of the segmented gray matter (GM), ...
Understanding the development of the human brain is challenging because imaging an immature brain encounters several difficulties. First, partial volume effects due to the small size of the brain associated with an already complex pattern of gyrification (Fig. 1) hamper cortex edges detection. Second, the GMWM contrast is weak due to unmyelinated white matter. Finally, the human brain undergoes...
Normalization of neuroimaging studies to a stereotaxic space allows the utilization of standard volumes of interest (VOIs) and voxel-based analysis (SPM). Such spatial normalization of PET and MRI studies requires a high quality template image. The aim of this study was to create new MRI and PET templates of F-DOPA and C-(+)-dihydrotetrabenazine (C-DTBZ) of the Macaca fascicularis brain, an imp...
