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.
For an overview, see CIP TCGA Radiology Initiative .
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 patientPlease read the Collection descriptions / summaries for a sense of the cohort contained within a particular Collection. Some Collections contain screening trials (a mixture of non-cancer, benign, and malignant may be present) like LIDC-IDRI or NLST. Other Collections focus on metastatic disease. A few TCIA Collections were created as publicly available COVID-19 datasets, unrelated to cancer. Several Analysis Results datasets are available, highlighting different parts of tumors like GTV, necrosis, etc.
