There are 24 3D multi-modality MRI data sets of at least 7 IVDs of the lower spine, collected from 12 subjects in two different stages in a study investigating the effect of prolonged bed rest (spaceflight simulation) on the lumbar intervertebral discs. Each subject at each stage was scanned with a 1.5-Tesla MRI scanner of Siemens using Dixon protocol. Thus, each 3D multi-modality MRI data set contains four aligned high-resolution 3D volumes: in-phase, opposed-phase, fat and water images. In total we will have 96 high resolution 3D MRI volume data. For each IVD, reference manual segmentation is provided in the form of binary mask. All images (four volumes per patient) and binary masks (one binary volume per patient) are stored in the Neuroimaging Informatics Technology Initiative (NIFTI) file format.
There are two stages in the challenge. In stage 1, a training data consisting of 16 multi-modality MRI data sets from 8 subjects and the associated reference segmentations will be released for method development. In stage 2, an on-site competition will be organized for which a test data will be used. For the test data, the associated reference segmentation are known to challenge organizer only, thus, they will be used in the on-site competition for performance evaluation purpose.
