Health Consequences of Having Too Many CT Scans

Computed Tomography (CT) scans are an increasingly used X-ray-based tool for providing a three-dimensional view of a particular organ or tissue. The value of CT scanning to diagnose injury, cancer and other health problems is undisputed. But are these scans being used too frequently, in some cases unnecessarily" What are the health consequences of having too many CT scans over the course of a person’s life"
