Quizplus · Accepted Answer

A CT scan produces a three-dimensional image of the internal structures of the body, whereas a conventional X-ray only produces a two-dimensional image. CT scans also have higher radiation exposure than X-rays, so they are not necessarily considered safer. There is no such thing as a four-dimensional image.
