813 808 abdominal CT cases from the seminal department of defense (Virtual) CT Colonography clinical trial of testing 3D visualization of CT slices as an aid to colon polyp detection. Results were reported in N Engl J Med. 2003 Dec 4;349(23):2191-200 by PJ Pickhardt. The study resulted in polyp detection sensitivities in the 93% range, which approximated that of optical colonoscopy in the same patients. The results were published in NEJM in 2003 and the study was considered ground-breaking by the colon-polyp screening community. Original CT digital files from the study cases obtained at WRAMC and NMC San Diego were transferred to NCIA NBIA to serve as a resource of CTC CAD research and commercial development. The collection contains the original DICOM CT image studies and data abstracts of the radiology and optical colonoscopy reports, as well as pathology reports of removed polyps.
