The National Cancer Institute (NCI) has exercised a series of contracts with specific academic sites for collection of repeat "coffee break," longitudinal phantom, and patient data for a range of imaging modalities (currently computed tomography [CT positron ] positron emission tomography ([PET) CT] CT, dynamic contrast-enhanced magnetic resonance imaging [DCE MRI]), diffusion-weighted [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 on 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-11.150.html.


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

...


The RIDER project will be replaced when the QIN initiative is fully implemented as this . 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 datametadata: http://grants.nih.gov/grants/guide/pa-files/PAR-11-150.html.

  • Download the related publication: Zhaob-RepeatCT Radiology2009.pdf.
  • 2012-10-18 Update: It was brought to our attention that the RIDER-8509201188 patient contained 2 identical image series rather than the correct secondary/repeat series. The duplicate series has been removed (UID: 1.3.6.1.4.1.9328.50.1.64033480205396366773922006817138551096), but we are unable to obtain the correct series at this point.

  • Repeat measurements: PET/CT phantoms.
  • Consists of repeat measurement PET/CT phantom scan collections carried out under the aegis of the Society of Nuclear Medicine (SNM) to discern the uniformity of clinical imaging instrumentation at various sites. They were obtained in cooperation with Society of Nuclear Medicine SNM as a resource for increased quantitative understanding of machine acquisition, analytic reproducibility and image processing.

  • 2012-02-22 Update: It was brought to our attention that RIDER-1817358092 and RIDER-2617411955 appeared to be the same patient.  We have gone back to University of Washington and confirmed this is to be true.  For now, we will leave both patients in place but plan to eventually delete RIDER-1817358092.  RIDER-2617411955 contains some additional series not found in the other patient ID and is what we would advise users to utilize in their research.

This data collection was originally supported under supplemental funding for the Lung Image Database Consortium (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 the M.D. Anderson Cancer Center and several of the LIDC academic sites. The data is not annotated and is not hosted in TCIA The Cancer Imaging Archive but can be downloaded from the National Biomedical Imaging Archive (NBIA).
