      • Longitudinal MRI Data in Nondemented and Demented Older Adults

  • ADNI

      • Alzheimer’s Disease Neuroimaging Initiative (ADNI) unites researchers with study data as they work to define the progression of Alzheimer’s disease. ADNI researchers collect, validate and utilize data such as MRI and PET images, genetics, cognitive tests, CSF and blood biomarkers as predictors for the disease.


      • The Federal Interagency Traumatic Brain Injury Research (FITBIR) informatics system: MRI, PET, Contrast, and other data on a range of TBI conditions


      • STructured Analysis of the Retina: This research concerns a system to automatically diagnose diseases of the human eye.

  • Cancer Digital Slide Archive

      • Whole-slide images from The Cancer Genome Atlas's (TCGA) glioblastoma multiforme (GBM) samples

  • The Cancer Imaging Archive

      • The image data in The Cancer Imaging Archive (TCIA) is organized into purpose-built collections of subjects. The subjects typically have a cancer type and/or anatomical site (lung, brain, etc.) in common.

  • SICAS Medical Image Repository

      • Post mortem CT of 50 subjects

      • CT, microCT, segmentation, and models of Cochlea

      • Copies of select challenge data (e.g., BRATS2015)

  • Johns Hopkins Medical Institute's DTI collection

      • DTI Atlases: adults, children, ...

  • Duke Center for In Vivo Microscopy
