Multimodal Brain Tumor Segmentation Challenge 2020: Tasks

Tasks' Description and Evaluation Framework

In this year's challenge, 3 reference standards are used for the 3 tasks of the challenge: 1) manual segmentation labels of tumor sub-regions, 2) clinical data of overall survival, and 3) uncertainty estimation for the predicted tumor sub-regions.

Participants are highly encouraged to participate in more than one task. However, they are not required to.

In favor of transparency and reproducibility, this year we will make publicly available (by the end of the challenge) the scripts used in CBICA's IPP for the evaluation of the participating methods. Furthermore, we intend to make available the actual software tools we have been using to pre-process the BraTS data.

BraTS Tumor Sub-regions
Glioma sub-regions. Image patches with the tumor sub-regions annotated in the different MRI modalities. The image patches show from left to right: the whole tumor (WT - yellow) visible in T2-FLAIR (Fig. A), the tumor core (TC - orange) visible in T2 (Fig. B), the enhancing tumor (ET - light blue) visible in T1-Gd, surrounding the cystic/necrotic components of the core (green) (Fig. C). The segmentations are combined to generate the final labels of the tumor sub-regions (Fig. D): edema/invasion (yellow), non-enhancing solid core (orange), necrotic/cystic core (green), enhancing core (blue).
