Virtual colonoscopy, or CT colonoscopy, is a non-invasive CAT scan screening for colorectal cancer, eliminating the worry and discomfort of testing for many people. Research findings published in The New England Journal of Medicine indicate that virtual colonoscopy is as effective as optical colonoscopy at detecting cancer and pre-cancerous lesions.
Detecting polyps and cancer early allows for treatment at a stage when the disease can either be prevented or cured before it can spread to other parts of the body.
Colorectal cancer is the second leading cause of cancer related deaths in the nation. Early detection is a prime defense in the battle against disease and the virtual colonoscopy eliminates the worry and discomfort of testing for many people. In the early stages, colorectal cancer causes no symptoms. Most colorectal cancers begin as small precancerous polyps that can take 3-10 years to evolve into cancer. Approximately 8% to 12 % of untreated polyps become cancerous tumors. When screening is performed regularly, polyps can be removed before they have the chance to become cancerous
"The good news is that this gentler, non-invasive type of screening will attract many patients to take the test. The 3-D images of the colon are of the highest quality and are able to detect even small polyps. Patients are amazed at how easy and quick the virtual colonoscopy screening is," states Dr. Maurice Poplausky, Chairman of Diagnostic Imaging at the hospital.
