BRAIN TUMOR SEGMENTATION

This year we also provide the naming convention and direct filename mapping between the data of BraTS'21-'17, and the subjects used from the data collections of TCGA-GBM, TCGA-LGG, IvyGAP, and CPTAC-GBM, available through The Cancer Imaging Archive (TCIA) to further facilitate research beyond the directly BraTS related tasks... Consistent with the configuration of previous BraTS challenges, we intend to use the "Dice score", and the "Hausdorff distance (95%)". Expanding upon this evaluation scheme, we will also provide the metrics of "Sensitivity" and "Specificity", allowing to determine potential over- or under-segmentations of the tumor sub-regions by participating methods... All BraTS mpMRI scans are available as NIfTI files (.nii.gz) for Task 1 (Segmentation) and as DICOM (.dcm) files for Task 2 (Classification). These mpMRI scans describe a) native (T1) and b) post-contrast T1-weighted (T1Gd), c) T2-weighted (T2), and d) T2 Fluid Attenuated Inversion Recovery (T2-FLAIR) volumes,..
