File Description

Processed Images

List of all 5074 images (includes baseline and follow up images) [ADNI_MALPEM_all_5074.csv]
List of 1069 baseline images used for analysis [ADNI_MALPEM_baseline_1069.csv]
List of 802 m12 follow up images used for analysis [ADNI_MALPEM_m12_802.csv]
List of 532 m24 follow up images used for analysis [ADNI_MALPEM_m24_532.csv]

Features

All extracted cross-sectional (structural volumes) 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. [features_CrossSect-5074_LongBLM12-802_LongBLM24-532.zip]

Segmentations / Brain masks

5074 cross-sectional structural segmentations in 138 distinct anatomical regions (calculated with MALPEM) [MALPEM_cross-sectional_seg138_5074.zip]
5074 binary brain masks (calculated with pincram). Masks have been quality checked (baseline: visual, followup: automatic) [pincram_bin_brain_masks_5074.zip]
Lookup table for all segmented 138 brain structures [lut.csv]

Methodology

Multi-Atlas Label Propagation with Expecation-Maximisation based refinement (MALPEM) including pincram brain extraction is publicly available on github: [MALPEM]

We are working on releasing the actual source code of MALPEM within [MIRTK]
