Preparation

Patients scheduled for a PET scan should refrain from eating for four to six hours before the procedure. Those with morning appointments should skip breakfast. Those with afternoon appointments may have an early breakfast, but should skip lunch.

In addition, patients should avoid any caffeine-containing beverages, including coffee, tea, and soft drinks, for at least 12 hours before the test. Even coffee and tea that is labeled "decaffeinated" should be avoided, since they may nonetheless contain enough caffeine to block the full effectiveness of the stress test.

Patients should continue to take their usual medications on the day of the test. Patients who take medication for diabetes, however, should consult with their doctor beforehand about possible PET-related dosage adjustments.

Finally, patients who may experience claustrophobia (a fear of enclosed spaces) should inform both their physician and the staff of the Clinical PET Center about this possibility, so that this concern can be managed effectively. The PET scan device looks and feels similar to many other imaging devices, such as a CT scanner.

At the time the scan is scheduled, further details will be provided about how you should prepare for your test. Any questions you have will be answered as well.
