Patient Prep – Oncology Imaging

sm11256_HS_03

Preparation for your PET/CT imaging study is more critical than for other commonly performed imaging studies.

Clothing
Dress in warm, comfortable clothing, as some scanner rooms may be cool. Avoid wearing jewelry and clothes with metal fasteners and zippers.

Food and Drink
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. On the day of the scan, do not eat or drink anything except plain water for four to six hours before your scan. Drink several glasses of water before your scan to ensure hydration.

Medications
Take your regularly scheduled medications with water prior to arriving for your scan, unless instructed otherwise.

Diabetics
Inform the imaging facility ahead of time if you are diabetic to discuss specific instructions. You should test your blood sugar level before the scan; it should be approximately 100-200 mg/dL.
