BraTS 2018

BraTS 2018 是一个数据集，提供由医生注释的多模态 3D 脑 MRI 和地面实况脑肿瘤分割，每个病例由 4 种 MRI 模态（T1、T1c、T2 和 FLAIR）组成。注释包括 3 个肿瘤亚区——增强肿瘤、瘤周水肿、坏死和非增强肿瘤核心。注释被组合成 3 个嵌套的子区域——整个肿瘤 (WT)、肿瘤核心 (TC) 和增强肿瘤 (ET)。使用各种 MRI 扫描仪从 19 个机构收集数据

BraTS 2018 is a dataset that provides physician-annotated multimodal 3D brain MRI volumes and ground-truth brain tumor segmentation annotations. Each case consists of four MRI modalities: T1, T1c, T2, and FLAIR. The annotations cover three tumor sub-regions: enhancing tumor, peritumoral edema, necrotic and non-enhancing tumor core. These annotations are grouped into three nested sub-regions: Whole Tumor (WT), Tumor Core (TC), and Enhancing Tumor (ET). The data was collected from 19 institutions using various MRI scanners.
