Medical imaging exams — including CT scans — have been directly linked to greater life expectancy and declining cancer death rates. Medical imaging exams are also generally less expensive and safer than invasive procedures, such as exploratory surgery.
Like other X-ray-imaging exams, CT scans expose you briefly to a small, targeted amount of ionizing radiation, which helps create an image of structures inside your body. CT scans provide more-detailed images of more types of tissue than traditional X-rays do, which allows your doctor to detect and locate many medical conditions.
CT scans have various purposes. They include helping to diagnose a condition, guiding medical procedures, such as needle biopsies, and monitoring the effectiveness of certain treatments, such as cancer treatments.
At the low doses of radiation a CT scan uses, your risk of developing cancer from it is so small that it can't be reliably measured. Because of the possibility of an increased risk, however, the American College of Radiology advises that no imaging exam be done unless there is a clear medical benefit.Read the whole article
