@vchung Dear BraTS Project Team, I am a PhD researcher working on deep learning-based brain tumor segmentation using multimodal MRI data. I would like to request formal written permission to use the BraTS 2021 Adult Glioma dataset and the BraTS 2023 Adult Glioma dataset for non-commercial academic research and scholarly publication. The requested permission would cover the use of these datasets for research activities, including model development, training, validation, transfer learning, testing, evaluation, and comparative analysis. It would also cover the reproduction of selected de-identified MRI images and corresponding segmentation masks in research articles, subject to the applicable BraTS data-use conditions, required citations, repository acknowledgements, and case identification requirements. Where applicable, I would also appreciate confirmation that the official BraTS mapping information may be used to align case identifiers or label conventions across different BraTS releases. Could you please provide a formal permission letter or official written confirmation from an authorized BraTS representative covering the above uses? This confirmation may be submitted to academic journals as evidence of authorized dataset use and image reproduction. Thank you for your time and assistance.
