NCI Imaging Data Commons
The NCI Imaging Data Commons lets users explore medical images, including CT, MRI, PET, and slide microscopy datasets.
About NCI Imaging Data Commons
The NCI Imaging Data Commons is a web portal for exploring medical imaging datasets, including computed tomography (CT), magnetic resonance (MR), positron emission tomography (PET), and slide microscopy images. The site lists image collections with example browsing categories and shows portal-wide counts for the current data release. The portal is run by the U.S. National Cancer Institute, and the homepage describes it as a system for the public to view and analyze cancer data.
Use of each dataset is governed by the NCI Data Use Agreement specific to that dataset. The homepage notes that the site is a U.S. Government website intended for authorized use, that activity may be monitored, and that users should have no expectation of privacy for communications or data processed on it. Links to external websites are not endorsed by NCI, and those sites follow their own privacy policies.
