The process of taking a CT of the knee or legs begins by taking many different X-ray views at various different angles, which are then combined with the use of computer processing to create cross-sectional images of the bones and soft tissue inside of your body, including tissues inside of solid organ.
Ordinary X-ray testing does not show clear images of soft tissue, so doctors often request CT scanning to get a good image of soft tissue including organs, muscles, blood vessels, nerves, and the brain. Sometimes a contrast dye is used as it shows up clearer on the screen.
A quality CT scan of the knee will use multiple x-rays to make cross sectional pictures of the knee.
