What is colonography?
colonography is a visual recording of colon or colon obtained by means of computer tomography technology (CT). Like colonoscopy, the purpose of colonography is to test the large intestine for polyps or other abnormalities that could indicate a risk factor for colon cancer or other colon disease. Colonography is less invasive than colonoscopy, but compared to different risks and benefits. The day before, thorough cleaning from the intestines was required. Colonography does not require a sedation, although a slight relaxer of the muscle can be injected immediately before the procedure.
colonography is first obtained by slightly inflating the large intestine through the air. This destroys the large intestine to see any abnormalities that could be hidden inside the folds of the colon walls. Then a number of images with a CT device and the computer build up images together radiologist for reading.
Although colonography minimizes the risk of colon perforation and is lessInvasive than colonoscopy, the procedure has several disadvantages. Black and white images that have begun to make observation less obvious than polyps such as small lesions. Colonography also includes exposure to X -rays.
Another disadvantage for many patients lies in insurance companies. Most insurance companies will not apply to colonies as part of the recommended annual colon screening for patients over 50 years of age, although the procedure is cheaper than colonoscopy. Some insurance companies will pay for colonies if it is ordered as part of a diagnosis for a particular problem.
colonography serves as a good screening tool for the health of the colon, because many patients with testing actually do not have polyps presentation in their colon and the procedure is less invasive than colonoscopy. If polyps are found, it offers a traditional roundNoscopy The opportunity to perform immediate biopsy and remove all polyps if necessary. Patients who acquire colonography and have been found to have polyps will be sent for traditional colonoscopy. For people who, for whatever reason, are afraid of conventional colonoscopy, colonography is better than no screening. Talk to your doctor if you are worried about the colon screening.
