Brain MRI
The Brain MRI Dataset is a corpus of MRI images of the brain, annotated to allow the study of various neurological pathologies. It is used to develop models for the automated detection of tumors, strokes, lesions related to multiple sclerosis, and more generally for the analysis of brain abnormalities.
Approximately 1500 brain MRI scans, DICOM and NiFTI formats
Free access for academic research, according to the conditions of the publication platform. Some versions may require a prior access request
Description
The dataset includes:
- Anatomical and functional MRIs of patients with various pathologies
- Clinical annotations or segmentations (depending on the version)
- Formats compatible with standard tools (DICOM, NiFTI)
- Data from hospitals or open studies
Some subsets offer detailed annotations (e.g. tumor contours), while others are used for unsupervised training or automatic segmentation.
What is this dataset for?
The Brain MRI Dataset can be used to:
- Training models for the detection and classification of brain tumors
- Automatic analysis of lesions related to stroke or MS (multiple sclerosis)
- Neurodiagnostic research assisted by artificial intelligence
- The development of diagnostic support systems in neurology
- Brain segmentation for pre-surgical planning
Can it be enriched or improved?
Yes, via several methods:
- Finer manual annotation with tools like ITK-SNAP or 3D Slicer
- Addition of contextual clinical data (age, functional score, follow-up imaging)
- Fusion with other bases such as BRATS (Brain Tumor Segmentation Challenge)
- Data increase to improve robustness (3D transformation, synthesis)

Frequently Asked Questions
Does this dataset contain segmented annotations?
Some versions include manual segmentations of tumors or lesions. Others require additional annotation depending on usage.
Is it suitable for 3D models?
Yes. The NiFTi format allows volume processing, ideal for 3D CNN, U-Net 3D or ViT 3D architectures.
Can this dataset be used to study anomalies other than tumors?
Yes. MRIs can reveal vascular, inflammatory or degenerative abnormalities, depending on the cases present in the corpus.
