The correlation between different variants of the Circle of Willis (CoW) and cerebrovascular disorders such as stroke, aneurysms and mental disorders is not yet well understood. A step towards a better understanding of the role of CoW in the aforementioned diseases is the automatic labeling of main vessels. In this work we tested three different approaches and observed high mIoU value of 0.870. As such the automatic anatomical labelling of the CoW seems feasible for clinical evaluation of the association of different anatomical variants with the risk factors of cerebrovascular pathologies.
