Manual segmentations of white matter hyperintensities from a subset of 7 ADNI subjects scanned three consecutive years, for inter-/intra-observer reliability analyses

This dataset contains structural magnetic resonance imaging (MRI)-derived data from 7 randomly selected participants enrolled in the Alzheimer's Disease Neuroimaging Initiative (ADNI) project. These data are binary masks of white matter hyperintensities (WMH), all obtained from 21 MRI scans (acquired at three consecutive study visits spaced 12 months apart). These masks were generated using semi-automatic segmentation (i.e., combined thresholding and manual tracing or manual editing of masks) on Mango Version 4.0, available from http://ric.uthscsa.edu/mango/ .
