PET/CT scan: You need to fast for 4 hours first, then you will recieve an injection of a small amount of radioactive glucose (i.e. Sugar). Next you will sit in a recliner chair for about 70 minutes to allow the glucose to distribute throughout you. Then you will lie on your back on the pet/ct scanner (a tunnel shaped machine) for 20 minutes. There are no side effects from the test or restrictions afterwards.
