How to Prepare for the Test?

Inform the technician or physician of ALL medications you are currently and have recently been taking, since they may interfere with the isotopes given for the exam. Also be sure to mention any recent imaging studies involving injected contrast media (dye) and oral or rectal contrast (such as from gastrointestinal studies) since they may also interefere.

You must sign a consent form before the radioactive compound is given. You may need to fast overnight before the test. Depending on the region being scanned, you may need to wear a hospital gown. Remove jewelry, dentures, and other metal that may affect the scan by blocking the gamma rays from the detectors.

The preparation you can provide for this test depends on your child's age and experience. For specific information regarding how you can prepare your child, see the following topics:
