What does the equipment used in a PET scan look like?

Hossein Jadvar (Doctor) gives expert video advice on: How does a PET scan work?; How should I prepare for a PET scan?; Why do I have to fast before a PET scan? and more...

A PET scanner, as I mentioned, is very similar from the outside to an MRI scanner or a CT scanner. It basically has a bore and a bed. The patient lies on the bed and the bed moves through that hole, or that bore. The patient is then positioned appropriately in that bore which is surrounded by detectors which detect the gamma rays coming off from the inside of the patient. And therefore from outside a PET scanner this doesn't really look that much different from what you may have seen with an MRI scanner or a CT scanner.
