Multimodal Brain MRI and Clinical Data for Olfactory Groove Meningioma Patients

A prospective, single-center dataset includes multimodal magnetic resonance imaging and longitudinal clinical data from patients with olfactory groove meningiomas, acquired before and after surgical intervention. The dataset, published by Elena Filimonova on figshare in May 2026, comprises high-resolution structural MRI, diffusion MRI, resting-state functional MRI, segmentation masks, and neuropsychological assessments. Imaging data were acquired using a standardized protocol, processed with reproducible pipelines, and organized in BIDS format.

Use Cases

• Analyzing tumor-related brain alterations based on multimodal MRI data mentioned in the description
• Developing imaging biomarkers for olfactory groove meningiomas based on structural, diffusion, and functional MRI
• Studying postoperative cognitive and behavioral recovery based on longitudinal clinical and neuropsychological assessments
• Training segmentation models for tumor and peritumoral edema based on provided segmentation masks

Strengths

• Data is organized in the BIDS format, which supports reproducible research and secondary analyses
• Imaging data were acquired using a standardized protocol and processed with reproducible pipelines, including quality control
• Includes longitudinal clinical data acquired before and after surgical intervention

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is relatively small at 1018.0 KB, indicating limited scope
