Please consult the Citation & Data Usage Policy for each Collection you’ve used to verify any usage restrictions. Some collections have additional copyrights or restrictions associated with their use which we have summarized at the end of this page for convenience. Most collections are freely available to browse, download, and use for commercial, scientific and educational purposes as outlined in the Creative Commons Attribution 3.0 Unported License.

Citing TCIA (general)

For any manuscript developed using data from The Cancer Imaging Archive (TCIA) please cite the relevant collection citations (see below) as well as the following TCIA publication:

Clark K, Vendt B, Smith K, et al. The Cancer Imaging Archive (TCIA): Maintaining and Operating a Public Information Repository. Journal of Digital Imaging. 2013; 26(6): 1045-1057. doi: 10.1007/s10278-013-9622-7. (link)

Please contact us at help@cancerimagingarchive.net so we can include your work on our Related Publications page.  We also encourage researchers to tweet about their TCIA-related research with the hash tag #TCIAimaging.

Citing Specific TCIA Collections

Each published TCIA Collection has an associated data citation.  When citing a TCIA collection, be sure to use the full data citation rather than citing the wiki page as a URL. Researchers can use https://citation.crosscite.org/ to create citations in the accepted format for most major publishers if you paste in the Digital Object Identifier (DOI) from a TCIA dataset. Consult the Citation & Data Usage Policy found on each Collection’s summary page to learn more about how it should be cited and any usage restrictions.  For some collections, there may also be additional papers that should be cited listed in this section.
