- Abstract summary: We propose a new aggregation of two deep learning frameworks namely, DeepSeg and nnU-Net for automatic glioblastoma recognition in pre-operative mpMRI.
Our ensemble method obtains Dice similarity scores of 92.00, 87.33, and 84.10 and Hausdorff Distances of 3.81, 8.91, and 16.02 for the enhancing tumor, tumor core, and whole tumor regions.

- Abstract: Glioblastomas are the most aggressive fast-growing primary brain cancer which
originate in the glial cells of the brain. Accurate identification of the
malignant brain tumor and its sub-regions is still one of the most challenging
problems in medical image segmentation. The Brain Tumor Segmentation Challenge
(BraTS) has been a popular benchmark for automatic brain glioblastomas
segmentation algorithms since its initiation. In this year's challenge, BraTS
2021 provides the largest multi-parametric (mpMRI) dataset of 2,000
pre-operative patients. In this paper, we propose a new aggregation of two deep
learning frameworks namely, DeepSeg and nnU-Net for automatic glioblastoma
recognition in pre-operative mpMRI. Our ensemble method obtains Dice similarity
scores of 92.00, 87.33, and 84.10 and Hausdorff Distances of 3.81, 8.91, and
16.02 for the enhancing tumor, tumor core, and whole tumor regions on the BraTS
2021 validation set, individually. These Experimental findings provide evidence
that it can be readily applied clinically and thereby aiding in the brain
cancer prognosis, therapy planning, and therapy response monitoring.
