What's Contrast?
Sometimes, doctors use a special dye called contrast to help the pictures show more details.
Before the scan, a nurse might put a small tube, called an IV, into your arm to give you the contrast dye.
You might feel a little cool or tingly when the contrast goes into your body.
Just like a regular CT scan, you need to lie very still while the machine takes pictures.
The machine moves around you, taking pictures from different angles.
Even though it might feel a bit strange, the scan itself is painless and safe.
Contrast helps doctors see certain parts of your body more clearly, like blood vessels or organs.
After the scan, you can go back to your regular activities. The contrast dye will leave your body naturally.
