Questions about Downloading Images
Questions about the TCGA-related imaging data
How do I find additional information about brain tumors?
Please refer to The Cancer Genome Atlas-Glioblastoma Multiforme (TCGA-GBM) collection for well-documented brain-tumor images as described here: https://wiki.cancerimagingarchive.net/display/Public/TCGA-GBM. (This wiki page also links to pages describing related research activities and related resources.)
In the Related Data section, there is a link to a blank GBM Case Quality Control Form that details the kinds and descriptions of clinical data collected. The data are freely available from the TCGA Data Portal: https://tcga-data.nci.nih.gov/tcga.
Once there, click on the link to GBM data. Since TCIA does not host the TCGA Data Portal, we do not offer guidance for browsing the Data Portal.
The TCGA-Lower Grade Glioma (LGG) collection is another set of brain tumor images: TCGA-LGG.
Questions about Tumors
Do the exams in TCIA show both malignant and benign tumors?
All patients who are part of TCIA at this time are cancer-positive by definition. We have no collections of non-malignant tumors or healthy patients. The only exception would be patients with multiple tumors who might have a benign tumor in addition to a malignant tumor, but at least one tumor will be malignant in each patient.
Questions about Limited Access Collections
How do I access National Lung Screening Trial (NLST) data?
Access to NLST images and data requires approval of the National Cancer Institute (NCI). For details, please see: https://biometry.nci.nih.gov/cdas/studies/nlst.

The site gives me problems, and error windows have popped up while I am trying to search or download images.
Our technical support team may ask you to answer these three questions if you're having difficulty with our website:
Which operating system are you using? (Typical examples would be Windows8, Mac OSX, Redhat Linux)
- Which browser (and version of that browser) are you using? (Typical examples would be Safari, Internet Explorer, Firefox, Chrome)
- Is Java installed on your machine, (and which version of that java are you using)? (Typical example would be yes, Java7 (u67))
To find your OS, browser, and java version, you may find the guide at Discover your OS Browser and Java Version helpful. The next step would be to test the site (but not necessarily click "download my basket") on another machine like a home laptop, to see if perhaps your institution has set, for example, a special layer of security on its network. The next step would be to email email@example.com to schedule an appointment for a webex teleconference with our technical support team to work with you interactively to facilitate access.
