We are doing some research about morphological properties of brain tumors, in particular we are interested in menigiomas and we are looking for establishing possible correlations of these morphological properties with tumor grading. Unfortunately, the databases at our disposal are not complete, there is a lack of meningiomas grade III, which are supposed to be anaplastic or malignant, and also they are extremenly rare.
These are some of the available recommended imaging databases for meningioma cases:
1. The Cancer Imaging Archive (TCIA): TCIA provides a large archive of medical images, including MRIs and CT scans, with associated metadata. It includes datasets for brain tumors, including meningiomas. Website: https://www.cancerimagingarchive.net/
2. Radiopaedia: A free, community-contributed resource with thousands of annotated radiological images. It includes meningiomas with classifications based on grading. Website: https://radiopaedia.org/
3. Harvard Dataverse: A repository of datasets, including medical imaging, with some contributions focusing on brain tumor research. Website: https://dataverse.harvard.edu/
4. BraTS (Brain Tumor Segmentation Challenge):Focuses on gliomas but may include meningiomas as part of some datasets. Useful for segmentation and grading tasks. Website: https://www.med.upenn.edu/sbia/brats2018/data.html
5. Meningioma-Specific Datasets from Research Groups:Look for published studies on meningiomas. Authors often share imaging datasets upon request or in supplementary materials.
6. National Institutes of Health (NIH) Clinical Imaging Database: Offers imaging datasets collected from clinical trials, including brain tumors. Website: https://clinicaltrials.gov/ (Search for meningioma imaging studies)
7. Hospital and University Archives: Leading institutions, such as Mayo Clinic, Cleveland Clinic, or Stanford University, often maintain private or public databases of radiological studies, including meningiomas.
8. Elsevier Imaging Hub: Contains a wealth of medical imaging data, including meningiomas. Requires a subscription. Website: https://www.elsevier.com/
9. ProScan Imaging Educational Foundation:Focused on neuroradiology with examples of brain tumors, including meningiomas. Website: https://www.proscan.com/
For grading availability, check specific datasets for WHO grades of meningiomas.
Generally, ensure you have appropriate ethical approvals (e.g., IRB clearance) for accessing and using clinical imaging data. Verify if the dataset includes WHO grading (e.g., Grade I, II, III) and metadata like histopathology.
