Good news here...and they are done very quickly...and are much less expensive than the full test done as an outpatient at the hospital with no anesthesia...BD
Two of the largest studies yet of "virtual colonoscopy" show the experimental technique works just as well at spotting potentially cancerous growths as the more invasive method. It's also quicker and cheaper. The X-rays can help sort out who really needs the full exam and removal of suspicious growths, called polyps. In one study, only 8 percent of patients had to have follow-up traditional colonoscopies, which are done under sedation and carry a small risk of puncturing the bowel. But what some people consider the most unpleasant part can't be avoided: drinking laxatives to purge the bowel so growths can be seen.
