How is a positron emission tomography (PET) scan done?

ANSWER

A PET scan usually lasts 45-60 minutes. You will be asked to lie down on a flat table that is next to a scanner computer and a camera. You will then be given a chemical called a tracer through an IV. After that, the doughnut-shaped scanner will move in circles around you. While the camera takes pictures of patterns left by the tracer inside your body.

Afterward, you usually will be asked to drink a lot of water or liquids for a day to help flush out the tracer chemical. You'll usually get your test results in a day or two.
