CAD detected cancer in two patients while optical colonoscopy initially detected only one. The colonoscopist found the second cancer after getting word that virtual colonoscopy had detected an abnormality.

"The fact that this worked so well on a large number of patients indicates that this is a robust technique," says Dr. Summers. "We believe it will work well in clinical practice, but more testing in the clinical environment still is needed."


"Research into better ways to screen for and prevent disease is an important aspect of NIH's clinical research mission," says John I. Gallin, M.D., director of the NIH Clinical Center. "Studies like this demonstrate how collaboration enriches research. We appreciate the contribution of patients, who are our partners in research, and the teamwork of our colleagues."

Screening patients came from National Naval Medical Center in Bethesda, Maryland, Walter Reed Army Medical Center in Washington, D.C. and San Diego Naval Medical Center.

This study was done in conjunction with researchers from the National Naval Medical Center, Walter Reed Army Medical Center and Uniformed Services University of the Health Sciences in Bethesda, Maryland. Jianhua Yao, Ph.D., Perry J. Pinkhardt, M.D., Marek Franaszek, Ph.D. Ingmar Bitter, Ph.D., Daniel Brickman, B.S., Vamsi Krishna, B.A., J. Richard Choi, ScD, M.D participated in the study.

The NIH Clinical Center is the clinical research hospital of the National Institutes of Health. Through clinical research, physicians and scientists translate laboratory discoveries into better treatments, therapies and interventions to improve the nation's health.

The National Institutes of Health (NIH) -- The Nation's Medical Research Agency -- includes 27 Institutes and Centers and is a component of the U. S. Department of Health and Human Services. It is the primary Federal agency for conducting and supporting basic, clinical, and translational medical research, and it investigates the causes, treatments, and cures for both common and rare diseases.
