We want you the force fluids (water, coffee or tea without cream or sugar) so you will be well hydrated for the exam. This helps clear the radiotracer from the kidneys. Please proceed with your regular medications. No exercise for 24 hours prior to your appointment time. (Intense physical activity will cause an increase uptake of the radiotracer, and can cause a false positive reading). There will be an hour delay from time of injection to time of scan PET (BRAIN) You will need to lie quietly in a darkened room without significant auditory or visual stimuli for 30 minutes prior to the injection and 30 min after the injection. Auditory and visual stimuli cause alterations in the scan that can confuse interpretation. There will be an hour delay from time of injection to time of scan. Scanning is usually 45-60 minutes For all other preps, please call our office at 702-254-5004
