Project Summary

The Cancer Imaging Program (CIP) with the cooperation of several of the TCGA GBM tissue-contributing institutions has archived a large portion of the diagnostic MRIs of the genetically-analyzed cases. That genetic data resides in the TCGA data portal. These images, using their TCGA identifier tags allow researchers to explore the genomic, clinical, and pathological data being stored within the TCGA Data Portal. These data sets therefore permit a link between radiological phenotype and tissue genotype. Although the present image archive has, for the moment, only acquired GBM images, over time, images from new TCGA-studied tumor types will be acquired and made available on the public NBIA archive.

Informatics software for use with this data has also been developed as part of the caBIG TCGA Enterprise Use-Case project. This caBIG enterprise use-case enables TCGA images stored in NBIA to be displayed on three different free and/or open source DICOM viewer workstations that possess annotation and markup capabilities based on Annotation Imaging Markup (AIM).

At present, the caBIG Imaging Workspace completed Phase I of this Enterprise Use-Case. ClearCanvas (Windows OS), Osirix (Mac) and XIP (caBIG open source/cross platform) were customized to allow retrieval of images from NBIA over the caGrid, markup by AIM standards, and storage back to an AIM-E Grid data service. More information can be found on the TCGA Radiology Project Phase I Homepage.

  • Navigate to http://imaging.nci.nih.gov
  • Click the "Search Images" link in the center of the page
  • Scroll down through the search criteria until you see the "Collections" section
  • Select the "TCGA" check box
  • Press "Submit"

This will return the full list of cases included in the collection. To download the associated DICOM images:

  • Press the "Check All" button and then "Add to Basket"
  • Press the "View My Basket" button at the bottom of the page (or "View Contents" in the left menu bar)
  • Press the "Download Manager" button to open a Java applet and specify where you'd like to save your images
