What is the difference between CT scans and X-rays?

X-rays and computed tomography (CT) scans are primarily used to visualize bony structures. CT scans actually use multiple specialized X-rays to view the body area from different angles and then give multiple cross-sectional images of it. The benefits of better visualization offered by CT over X-ray must be weighed against the risks of significantly increased radiation exposure and increased time and costs of the procedure.
