Multiple Sclerosis Lesions segmentation challenge

Multiple Sclerosis Lesions segmentation challenge

As part of an ongoing effort, towards automatic segmentation of MRI scans of MS patients, of the OFSEP (French registry on multiple sclerosis aiming at gathering, for research purposes, imaging data, clinical data and biological samples from the French population of multiple sclerosis subjects) and FLI (France Life Imaging), we are organizing a challenge on MS lesions segmentation. This challenge will take place during MICCAI 2016, on October 21st 2016.

The goals of this challenge are multiple. We first aim at evaluating state-of-the-art and advanced segmentation methods from the participants on a database following a standard protocol (used by OFSEP, see this article for more information). For this, we will evaluate both lesion detection (how many lesions were detected) and lesion segmentation (how precise the lesions are delineated) on a multi-centric database (38 patients from four different centers, imaged on 1.5 or 3T scanners, each patient being manually annotated by seven experts).

In addition to this classical evaluation, the goal of this challenge is also to provide a common infrastructure on which the algorithms will be evaluated (more details here). This infrastructure will enable a fair comparison of the algorithms in terms of running time comparison and ensuring all algorithms will be run with the same parameters for each patient (which is required for a truly automatic segmentation).
