BraTS2023-MET（2023年脑转移瘤分割挑战赛）是BraTS2023五大分割子任务之一。与常规针对脑胶质瘤分割的BraTS挑战赛不同，本子任务旨在从多模态MR图像（mpMRI）中分割脑转移瘤。该数据集于2023年6月发布，共计328例病例，其中包含238例带标注的训练病例，每例提供四种MR序列（t1w、t1c、t2w、t2f）的输入图像以及脑转移瘤分割结果。标注内容主要包括非强化肿瘤核心区（Non-Enhancing Tumor Core，NETC）、周围非强化FLAIR高信号区（Surrounding Non-Enhancing FLAIR hyperintense signal，SNFH）和强化肿瘤区（Enhancing Tumor，ET）。验证集仅提供图像无标注，可通过官网提交验证结果，测试集数据未公开。
