Dataset: MALPEM-ADNI: Features, binary masks, segmentations for 5074 ADNI subjects

We employed a recently validated method (MALPEM) for robust cross-sectional and longitudinal segmentation of MR brain images from the Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort. Specifically, we segmented 5074 MR brain images into 138 anatomical regions and extracted time-point specific structural volumes and volume change during follow-up intervals of 12 or 24 months.

The following is a summary of the publicly available dataset. For more details please refer to the [doi] and the README of the current GIN repository.

Processed Images from the ADNI cohort

  • List of all 5074 images (baseline and follow up images, incl. VISCODE)
  • List of 1069 baseline images (incl. disease label) used for analysis 
  • List of 802 baseline and m12 follow up image pairs (incl. disease label) used for analysis
  • List of 532 baseline and m24 follow up image pairs (incl. disease label) used for analysis

Features

  • All extracted cross-sectional (structural volumes, asymmetry) and longitudinal (volume change rate) features and selected clinical information (e.g. disease labels). Note: Not all of those features have been used in the manuscript. Please, refer to the paper for details.

Segmentations / Brain masks

  • 5074 cross-sectional structural segmentations in 138 distinct anatomical regions (calculated with MALPEM)
  • 5074 binary brain masks (calculated with pincram). Masks have been quality checked (baseline: visual, followup: automatic) 
  • Lookup table for all segmented 138 brain structures
