During the Exam: A nurse or technologist will take you to a special room where you will receive an intravenous (IV) injection of the radioactive drug. Sometimes, you will be asked to inhale the drug instead. Then you will wait 30 to 90 minutes for the drug to travel through your body and accumulate in the tissues being studied. During this time, you will rest quietly and avoid movement. You won’t be able to feel the drug in your body.
