Wall Street Journal (subscription required), October 28, 2008

Virtual colonoscopy has been available for some time, but more medical centers are gearing up to offer the procedure at a time when new research shows it can be about as effective at finding large polyps as a standard colonoscopy. The cost of the virtual test can run from $500 to $1,500, or less than half the total cost of a standard colonoscopy. But the newer procedure is rarely covered by health insurers for routine cancer screening.
