Summary

The Reference Image Database to Evaluate Therapy Response (RIDER) database is a targeted data collection for the purpose of generating an initial consensus on how to harmonize data collection and analysis for quantitative imaging methods as applied to measure the response to drug or radiation therapy. The long term goal is to provide a resource to permit harmonized methods for data collection and analysis across different commercial imaging platforms, as required to support multi-site clinical trials, using imaging as a biomarker for therapy response. Thus the database should permit an objective comparison of methods for data collection and analysis as a national and international resource as described in the first RIDER white paper report (2006):

All the image data are DICOM compliant and the image, annotations and meta data formats meets all the requirements for caBIG and the NBIA.  The data collection has two phases as described below, which have resulted in several distinct image Collections.

RIDER Pilot (2005-2007)

This data collection was originally supported under supplemental funding for the LIDC U01 project and focused on the collection of longitudinal studies using X-ray CT for monitoring the response to therapy. The data came primarily from MDACC and several of the LIDC academic sites. The data is not annotated. However it contains a sub-set of 30 longitudinal cases that are annotated using the RECIST criteria.

RIDER Contracts (2007-Beyond)

NCI has exercised a series of contracts with specific academic sites for collection of repeat "coffee break" and longitudinal phantom and patient data for a range of imaging modalities (currently CT, PET CT, DCE MRI, DW MRI) and organ sites (currently lung, breast, and neuro). The goals are as follows:

  1. Develop a consensus on requirements for quantity assurance methods for longitudinal studies using phantom data as applied to each modality above,
  2. Develop a consensus on the stability of imaging platforms using repeat and longitudinal phantom measurements over the time period that therapy would be exercised,
  3. Develop a consensus on methods to measure the minimum change that can be measured using repeat and longitudinal patient or volunteer studies
  4. Provide access to results of measurements performed on these databases by each academic site to encourage a comparison on methodologies,
  5. Provide consensus-based juried publications to encourage a broad acceptance of the methods described above.
  6. Provide a resource for NCI research networks that address quantitative imaging such as the Quantitative Imaging Network QIN): http://grants.nih.gov/grants/guide/pa-files/PAR-08-225.html


The databases are being provided with a timely goal of 18 months time frame, namely from the time the contract was initiated and the published results within less than 2 years. The methods for data collection and analysis including results are described in the new Combined RIDER white Paper Report (Sept 2008):


The RIDER project will be replaced when the QIN initiative is fully implemented as this research network will be tasked to create database resources collected from phase 1-3 clinical trials, where clinical outcomes will be included in the meta data: http://grants.nih.gov/grants/guide/pa-files/PAR-08-225.html

  • ISMRM 2009 poster demonstrates how each of the "coffee break" exams were used as an estimate of each patient's null hypothesis, i.e. distribution associated with no change, and thus supports the estimate of the null's 97.5 percentile for subsequent estimation of early response to neoadjuvant chemotherapy on an individual patient basis.

Data Access

You can view and download these images on NBIA. You do not need to log in unless you want access to advanced features in the site. Simply follow these steps:

  • 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 check box for whichever RIDER sub-collection you are interested in
  • 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
