Ask Your Doctor
Before the scan, ask your doctor what you need to do to get ready.
Wear clothes that are easy to take off, like a T-shirt and pants with no metal.
Leave all your jewelry at home because metal can mess up the scan pictures.
You might need to stop eating a few hours before the scan. Your doctor will tell you when.
Drink plenty of water unless your doctor tells you not to.
Tell your doctor about any medicines you take. Sometimes, you might need to skip them.
Try to get a good night's sleep before the scan day.
Ask a family member to come with you. They can keep you company.
Stay super still so the camera can get the best pictures.
Once it's done, you can usually go home and do your normal stuff.
