摘要

Structural MR brain imaging is important in the understanding of regional brain changes in healthy aging and in disease processes. Current methods are often labour-intensive, requiring hours of manual tracing. SABRE (Semi-automatic Brain Region Extraction) is a new technique that allows rapid and reliable parcellation of cortical and subcortical brain regions. Utilization of SABRE in conjunction with a validated tissue-compartment segmentation program can provide measures of gray matter, white matter, ventricular CSF, and sulcal CSF measures for designated brain regions. We present data showing high inter-rater reliably for all regions, with correlations between 0.95 ― 0.99. Regional tissue measures of healthy young and healthy older adults were also examined, demonstrating the sensitivity of this protocol to brain volume changes that occur with aging.
