Guide To Positron Emission Tomography Scans (PET Scans)

Preparing For A PET Scan

This type of scan is done on an outpatient basis, meaning the patient who undergoes the test will be able to go home immediately afterward. Before having a positron emission tomography scan, a patient should inform their physician of all vitamins, herbal remedies, supplements, and medications they are taking. Some medications, supplements, and vitamins may require patients to follow extra instructions before their scan.

Patients should let their doctor known if they are pregnant or if there is a possibility they are pregnant. In most cases, patients will be instructed not to consume any food for at least six hours before their scan. If the positron emission tomography scan involves any part of their heart, they are usually advised to avoid consuming caffeine for twenty-four hours before their scan.
