The Whole Body Exam
The patient is injected with a radioactive tracer (which is a biologic substance that is similar to glucose and a small amount of radioactive material) called Fludeoxyglucose (F18) or FDG. Since the injection is a radioactive glucose there are no side effects. After the injection, the patient is to relax for 60 minutes to allow the tracer to distribute throughout the body.
The patient is instructed to empty their bladder and remove any metal. The patient is positioned on the table for the scan from the head to thighs. The scan time depends on your height and weight which is 15-20 minutes. After the scan, the patient is released and able to resume normal diet and activities without restrictions.
