What preparations are necessary?
Some biograph PET/CT scans require no preparation at all, while others might require you to modify your food, fluid, or medication intake prior to the scan. The scheduling Specialist or Technologist who helps you, will let you know specifically what to do before and after your scan. If possible, try to wear loose-fitting clothes on the day of your scan, and avoid caffeine so you won’t be restless. During the scan, all you have to do is relax, and lie as still as you can. You will first receive a small injection of a radiopharmaceutical contrast about 60 minutes before the actual scan. It will not make you feel any different. Depending on the type of study, you may also receive a contrast medium at the time of the CT portion. This is a dye that increases the quality of the CT images. The contrast medium may be administered orally, or by injection, or both. Some patients report a warm feeling or an unusual taste in their mouth from the contrast medium.
