What is a PET scan?  A positron emission tomography scan is an imaging test that uses a radioactive substance called a tracer to look for disease in the body  A PET scan shows how organs and tissues are working

How it works  The PET produces images of the body by detecting the radiation emitted from radioactive substances. These substances are injected into the body, and are usually tagged with a radioactive atom  The PET detects the gamma rays  8L4JKM 8L4JKM

Procedure  No eating for 4-6 hours prior  The tracer is given through an IV  Wait about an hour  Lie on table that slides into the scanner  The scanner picks up signals from the tracer  Stay very still

Why Get a PET Scan?  It can reveal the size, shape, position, and some function of organs  Test can be used to: Check brain function Diagnose cancer, heart problems, and brain disorders See how far cancer has spread Show areas in which there is poor blood flow to the heart

Risks  Minimal radiation is used Short-lived tracers are used  Tell doctor if you’re pregnant or breast feeding  Allergic reaction to the tracer material is rare  Some people experience redness, pain, or swelling at the injection site

Costs  Cost of scan: $3,000 - $6,000 Broken down into 3 areas ○ FGD Radiopharmaceutical Fees (~$527) ○ Technical Fees ($206-$939) ○ Professional Fees (~$1,880)  Expensive, but could be worth it  The machine its self is usually around $1.9 million
