According to CNN news, studies are showing that 'virtual colonoscopies' - which are much less invasive than the traditional scope exam - may be just as accurate in spotting potentially cancerous polyps.
As we all know (and dread), colonoscopies are recommended for those over the age of 50, though half those people seem to be skipping this uncomfortable, albeit preventive procedure. The x-ray based virtual exam could see those numbers increasing, though doctors have their reservations about this experimental technique.
Gastroenterologist Dr. Douglas Rex, who is also director of endoscopy at Indiana University, is following the studies. Because they are being conducted in several locations, he feels "we should have a pretty good sense of how it's going to perform in practice." His reservations regarding virtual colonoscopy is due to the fact that the procedure does not lead to the removal of the smallest polyps and exposes patients to radiation. (CNN)
Let's hope Superman has grown up from x-ray ogling Lois Lane's underpants and is shopping for a daytime job.
Dr. Rex is a professor of medicine and specializes in Gastroenterology. He practices in Indianapolis, Indiana.
