OpenMind: 114,000 3D Head and Neck MRI Scans from 800 Sources

114,000 3D MRI images of the head and neck region aggregated from 800 distinct OpenNeuro datasets by AnonRes. This collection is designed to facilitate the development of self-supervised learning methods for 3D medical imaging and was last updated in April 2025.

Use Cases

• Self-supervised pre-training for 3D medical imaging models using the 114,000 MRI volumes
• Image feature extraction for head and neck anatomical structures
• Benchmarking 3D reconstruction algorithms across diverse MRI acquisition protocols

Strengths

• 114,000 3D MRI images
• Aggregated from 800 distinct OpenNeuro datasets
• CC BY 4.0 license allows for broad research application

Limitations

• High variance in acquisition parameters and hardware due to the aggregation of 800 different source datasets
• Lack of explicit clinical labels or segmentation masks in the primary description
