Boundary Distance Loss for Intra-/Extra-meatal Segmentation of Vestibular Schwannoma

Vestibular Schwannoma generally progresses from the inner ear to the brain. We annotated a database containing 227 T2 MRI cases, gathered longitudinally on 137 patients, excluding post-operative cases. We suggest a staged approach, with the first stage handling the complete tumour segmentation and the second stage performing the intra-/extra-meatal segmentation with the T2 MRI and the mask obtained from the first stage. We'll try to improve the predictability of the predicted meat boundary with a task-specific loss, which we'll refer to as Boundary Distance Loss. The results are compared to the direct intrameatal extrameatal segmentation task's success, i. e. respectively for extrameatal and intrameatal regions, with the two-stage strategy and the Boundary Distance Loss, dramatically raising over the Baseline, which gave a score of 0. 7979+-0. 1346 for the extrameatal and intrameatal regions respectively.
