Search by modality, contrast and condition, then narrow down to the subjects you need: how many have T1w and FLAIR, are female, or are between 60 and 80.

Explore this selectionRadiology images and report extracts from all of Scotland's hospitals, linkable to national health records, analysed by approved projects inside a secure environment. 57.3 million studies of about 4.27 million patients from 2010 to 2018. Not downloadable.
Brain, heart and abdominal MRI, body DXA and carotid ultrasound of UK adults, linked to genetics and health records, used for imaging genetics, brain age, cardiac and body composition research. Over 100,000 participants aged about 44 to 87 at imaging. Access by application and fee.
Chest radiographs paired with the free-text radiology reports written during routine emergency care, widely used for chest X-ray classification, report generation and vision-language research. 377,110 images from 227,835 studies of 65,379 patients at a Boston hospital.
Chest radiographs with labels for common findings taken from radiology reports, including an uncertain state, one of the standard benchmarks for multi-label chest X-ray classification. 224,316 images of 65,240 Stanford patients with 14 labels and a radiologist-labelled validation set. Non-commercial use only.
Minimally preprocessed brain MRI pooled from hundreds of public sources, built for self-supervised pretraining of 3D models on clinical and research scans of many sequences. 260,927 scans of 55,378 subjects from 910 sources, downloadable without an account.
Routine clinical brain MRI, CT, PET and SPECT from patients who had EEG or sleep studies, linked to their neurophysiology recordings and radiology reports for multimodal brain research. Converted to BIDS NIfTI, with LLM-extracted findings and automatic sequence labels.
Head and brain MRI volumes pooled from 800 OpenNeuro datasets with masks and harmonized metadata, built for self-supervised pretraining, not for supervised tasks. 113,921 volumes of about 34,000 subjects, including diffusion-derived maps, under CC BY 4.0 on Hugging Face.
Frontal chest radiographs with disease labels mined from reports, one of the first chest X-ray sets large enough for deep learning, used for multi-label classification and weakly supervised localization. 112,120 images of 30,805 patients with 14 labels, age, sex, view and about 1,000 boxes.
Amyloid PET and cognitive testing from the screening stage of lecanemab prevention trials in cognitively unimpaired adults aged 55 to 80, shared for research on preclinical Alzheimer's disease and trial recruitment. 16,835 North American screens; data after randomization are not shared.
Standardized brain MRI and amyloid, tau and FDG PET from US Alzheimer's Disease Research Centers, checked and processed centrally and linked to clinical, cognitive and neuropathology data. Collected since 2021. Free on request under a data use agreement.
Brain MRI, genetics, mental and physical health, cognition and substance use data from US children followed from ages 9 to 10 into adulthood, to study how the brain develops through adolescence. 11,860 youth scanned every two years with structural, diffusion and functional 3T MRI.
Clinical amyloid PET scans and visit data from Medicare beneficiaries with mild cognitive impairment or dementia of uncertain cause, collected to test whether amyloid PET changes patient management. Images and clinical tables are shared through LONI after an application.
