- Cases. The fixed images of TopBrain's pairs, the MR angiographies: a test pair's image is a test case, a development pair's a development case.
- Images. The CT angiographies keep their native grids for registration; this segmentation task uses one MR angiography per patient.

About the data
- Truth
- contours by experts the dataset's 2025 voxel labels of the brain's arteries on each image, without the internal carotid and ophthalmic arteries: basilar and vertebral arteries, superior, anterior inferior and posterior inferior cerebellar arteries, posterior (P1-P2, P3-P4), middle (M1, M2, M3) and anterior (A1-A2, A3) cerebral arteries, posterior and anterior communicating arteries, anterior choroidal arteries, and a third A2 and A3 where there is one (30 classes)
