What is a nuclear medicine test?

Nuclear medicine is an imaging method that obtains pictures by giving the patient a small dose of radioactive material.  Images are taken with a special camera that can detect the location of the radioactive material within the body. 

What will happen during the exam?

The radioactive material will be given through an injection in the arm or by swallowing a capsule.  The area of the body be examined determines how the dose is given.  The radiation dose is comparable to a routine x-ray exam and there are no side effects with the radioactive material given.  The patient may be asked to lie or sit in front of the camera. 

How do I get ready for a nuclear medicine test?

For many of the exams there are no special preparations required, however if preparations are necessary, they will be explained at the time of scheduling.

How long does the exam take?

Scans range in time from a few minutes to several hours.  Some exams require a delay after the material is given, before imaging is started.  This is to allow the material to collect at the area of interest.
