Computerized tomography, otherwise known as CT or Cat scanning, has imaged 70% of non-elderly adults in the last 3 years. The use of this technology has been steadily rising, and we now perform a total of over 19,500 CT scans per day in the US. CT scans use a computer to organize x-ray data in such a way as to produce pictures that resemble cross sections of the human body, complete with bones, brains and soft tissues, tumors and blood vessels. The pictures are truly marvelous and have revolutionized the way we diagnose disease, allowing us to know many things about the insides of a person without actually cutting them open.
