MS segmentation challenge using a data management and processing infrastructure

A journal article is available at Nature scientific reports on the challenge results, it should be cited whenever using the challenge data or results. It is available at the following DOI: https://dx.doi.org/10.1038/s41598-018-31911-7. Supplemental results data is avilable at zenodo: http://doi.org/10.5281/zenodo.1307653

Data and format

53 datasets from 4 different sites and 4 different MRI scanners will be used. The provided MR sequences will include:
  • 3D FLAIR
  • 3D T1-w
  • 3D T1-w GADO
  • 2D DP/T2

The provided data are split into two sets (15 training data and 38 testing data) as shown in the following table. All 53 datasets include raw data in Nifti format. As of now, the challenge is currently closed for submissions. We are actively looking for ways to revive submissions for new algorithms to be evaluated in the same framework. For this reason, you may download in the meantime only the training database (after account registration) and no access to the testing database will be given yet.

Since April 8 2016, we have made available the 15 training datasets, allowing the teams to train their algorithms and tune their parameters, as two packages (zip files): 
 
  • one package with unprocessed datasets and manual lesion delineations from seven independent experts
  • one package with pre-processed datasets (denoised, registered, brain extracted, bias field corrected) using state-of-the-art pre-processing algorithms
 
To access these dataset, please register first your participating team on the website (Subscribe link on the overview page): the links to the two zip files appear at the bottom of this page once logged in. More details on the pre-processing and data are available in a README file inside each zip file. These zip files will be accessible to any registered user to the MS SEG challenge, subject to the following constraints: 
 
  • using these files or any results derived from the challenge require citation to the Scientific Reports article published on the challenge
  • these files shall not be distributed to third-parties
