VerSe: Large Scale Vertebrae Segmentation Challenge

Look well to the spine for the cause of disease - Hippocrates

What is VerSe?

Spine or vertebral segmentation is a crucial step in all applications regarding automated quantification of spinal morphology and pathology. With the advent of deep learning, for such a task on computed tomography (CT) scans, a big and varied data is a primary sought-after resource. However, a large-scale, public dataset is currently unavailable.

We believe VerSe can help here. VerSe is a large scale, multi-detector, multi-site, CT spine dataset consisting of 374 scans from 355 patients. The challenge was held in two iterations in conjunction with MICCAI 2019 and 2020. The tasks evaluated for include: vertebral labelling and segmentation.

Data

  • The dataset has four files corresponding to one data sample: image, segmentation mask, centroid annotations, a PNG overview of the annotations.

  • Data structure

    • 01_training - Train data
    • 02_validation - (Formerly) PUBLIC test data
    • 03_test - (Formerly) HIDDEN test data
  • Sub-directory-based arrangement for each patient. File names are constructed of entities, a suffix and a file extension following the conventions of the Brain Imaging Data Structure (BIDS; https://bids.neuroimaging.io/)

Example:
-------
training/rawdata/sub-verse000
    sub-verse000_dir-orient_ct.nii.gz - CT image series

training/derivatives/sub-verse000/
    sub-verse000_dir-orient_seg-vert_msk.nii.gz - Segmentation mask of the vertebrae
    sub-verse000_dir-orient_seg-subreg_ctd.json - Centroid coordinates in image space
    sub-verse000_dir-orient_seg-vert_snp.png - Preview reformations of the annotated CT data.

  • Centroid coordinates of the subject based structure (.json file) are given in voxels in the image space. 'label' corresponds to the vertebral label:
    • 1-7: cervical spine: C1-C7
    • 8-19: thoracic spine: T1-T12
    • 20-25: lumbar spine: L1-L6
    • 26: sacrum - not labeled in this dataset
    • 27: cocygis - not labeled in this dataset
    • 28: additional 13th thoracic vertebra, T13
