Before arriving at the imaging facility you should carefully follow our detailed patient preparation instructions. Correct preparation for your PET study is more critical than for other commonly performed imaging studies due to the fact that PET imaging depends on visualizing the distribution of the glucose based radiopharmaceutical throughout your body.
PET / CT scanner rooms can sometimes be kept at cooler temperatures, so please see that you wear warm comfortable clothing. Also, please avoid wearing jewelry or clothes with metal fasteners or zippers as you will be asked to remove those before the scan takes place.
Food and Drink
Please call the imaging facility for specific instructions. Generally, the day before your scan drink 6-8 glasses of water and limit the amount of sugar and caffeine you consume. Please refrain from eating or drinking any liquids, except water, for at least four to 6 hours before your scan.
Take your regularly scheduled medication with water prior to arriving for your scan, unless instructed otherwise. Please remember to bring a list of any and all medications that you are currently taking.
Inform the imaging facility ahead of time if you are diabetic to discuss specific instructions. Test your blood sugar level before the scan, it should be approximately 100-200 mg/dL.
