  • 基于BraTS 2023-GLI数据构建8类统一标签体系
  • 包含1251例标注,覆盖健康组织与未标注异常病灶
  • 适用于联合解剖-病灶分割与标签噪声研究

现有BraTS-GLI数据集虽广泛用于成人胶质瘤MRI分割,但其任务定义仅关注肿瘤亚区,未系统标注白质高信号(WMH)等共存异常。在联合分割任务中,这些未标注异常会引入特定任务噪声。为此,我们推出BraTS-GLI Anatomy-Lesion,一个基于BraTS 2023-GLI训练集构建的受控访问、仅含标签资源。该资源提供1,251个与四模态MRI对齐的八类统一解剖-病灶标签集,包含116例需图像修复的病例。数据分为394例纯净子集和857例扩展子集,每例含标签来源、修复需求、质量控制状态、访问条件、校验码及发布边界等元信息。相比原标注,该资源显著扩展了前景监督,纳入健康脑组织与此前未标注的共存异常。验证实验表明,使用MedNeXt模型和T1/FLAIR输入时,考虑WMH的监督在保持原域胶质瘤与外部WMH数据集健康组织分割性能的同时,提升了对共存病灶的敏感性,优于噪声对照训练。本资源适用于科学科研,支持联合解剖-病灶监督、标签噪声分析与可复现评估。数据可通过https://www.synapse.org/Synapse:syn75210889/wiki/获取,代码见https://github.com/xyx200/brats-gli-anatomy-lesion-code。数据资源DOI为10.7303/SYN75210889。

原文摘要 · Abstract (English)

Existing BraTS-GLI datasets provide a widely used benchmark for adult glioma MRI segmentation, but their task definition focuses on tumor subregions and does not systematically represent coexisting white matter hyperintensities (WMH). In joint segmentation settings, such unlabeled abnormalities introduce task-specific label noise by treating pathological regions as normal tissue. To address this limitation, we introduce BraTS-GLI Anatomy-Lesion, a controlled-access, labels-only derived resource built from the BraTS 2023-GLI training cohort. The resource provides 1,251 unified eight-class anatomy-lesion label sets aligned with the original four-modal MRI cases, including image-repair labels for 116 cases requiring repaired imaging inputs. The cohort is organized into a 394-case purified subset and an 857-case extended subset, with case-level metadata covering label source, image-repair requirements, quality-control status, access conditions, checksums, and release boundaries. Compared with the original BraTS-GLI annotations, the resource substantially expands foreground supervision by incorporating healthy brain tissues and previously unlabeled coexisting abnormalities within a unified label space. A validation study using MedNeXt and T1/FLAIR inputs suggests that WMH-aware supervision preserves healthy-tissue segmentation performance across both in-domain GLI and external WMH datasets, while improving sensitivity to coexisting lesions relative to noisy-control training. The resource is intended for scientific research and supports joint anatomy-lesion supervision, label-noise analysis, and reproducible evaluation. Data are available at https://www.synapse.org/Synapse:syn75210889/wiki/, and code is available at https://github.com/xyx200/brats-gli-anatomy-lesion-code.
