Reproducibility of intracranial volume measurement by unsupervised multispectral brain segmentation

摘要: To assess the inter-study variability of a recently published unsupervised segmentation method (Magn. Reson. Med. 1997;37:84-93), 14 brain MR studies were performed in five normal subjects. Standard deviations for absolute and fractional volumes intracranial compartments, which reflect experimental variability, smaller than 16.5 ml 1.1%, respectively. By comparing component with observed our reference database, an estimate biological database population was obtained.
