Definition

Segmentation and classification within the field of neuroimaging refers to the separation of different brain regions in a structural magnetic resonance imaging (MRI) T1 sequence into defined tissue classes or types (Ashburner and Friston 1997; Friston et al. 2002; Reddick et al. 1997). The most basic segmentations generally separate regions into gray matter (GM), white matter (WM), and cerebrospinal fluid (CSF). However, more specific regions of interest (ROI) can be defined and segmented as well. Some of the most common ROIs to be segmented in brain disease and injury research for clinical application include regions such as the thalamus, amygdala, lateral ventricles, hippocampus, caudate nucleus, and brainstem...
