Dataset Overview & Significance
The BraTS-MEN-RT dataset is the largest multi-institutional collection of expert-annotated MRI scans for meningioma radiotherapy planning. It comprises 570 T1-weighted post-contrast MRIs, including both intact and postoperative cases, from seven diverse medical centers. This rich data is crucial for developing and validating automated segmentation methods that can generalize across varied clinical settings, directly addressing the complexities of real-world RT workflows.
Methodology & Annotation Protocol
The dataset's rigorous annotation protocol involved senior radiation oncology residents and board-certified neuroradiologists. Initial segmentations were derived from institutional DICOM-RT data or an nnU-Net model trained on previous BraTS challenges, then meticulously revised to adhere to standardized meningioma RT guidelines (EORTC 22042-026042 and RTOG 0539). This ensures high-quality, clinically relevant ground truth for AI model training.
Clinical Relevance & Future Directions
AI-driven segmentation based on datasets like BraTS-MEN-RT promises to standardize GTV delineation, reduce inter-observer variability, and accelerate RT planning. The inclusion of native resolution images, extracranial anatomy, and SRS-specific artifacts makes the dataset uniquely suited for direct clinical integration, pushing the boundaries of automated methods for complex conditions like meningioma.

Case Study: Enhancing Radiosurgery Planning with AI
A patient undergoing Stereotactic Radiosurgery (SRS) for an intact meningioma in Meckel's cave presented unique challenges. Traditional skull-stripping methods would have excluded a significant portion of the lesion due to its proximity to the skull base. The BraTS-MEN-RT dataset's methodology, preserving extracranial anatomy and incorporating defacing instead of skull-stripping, enabled a comprehensive GTV delineation. AI models trained on this data accurately segmented the entire tumor, including parts that would typically be removed by pre-processing, demonstrating enhanced clinical applicability for complex cases.
AI-driven segmentation ensured complete tumor coverage for SRS, improving treatment accuracy and patient safety.
