    • Drink water beforehand to ensure you are well-hydrated for the test.
    • Take any of your regular medications as prescribed.
  • Wear warm, comfortable clothing – ideally without metal (zippers, snaps, etc.) If you forget, we will happily offer a gown or scrubs to wear during your test. Avoid wearing jewelry and metal hairpins that could affect the quality of the images.
  • If you’ve had any prior PET or CT scans performed somewhere other than Raleigh Radiology or WakeMed, please bring them with you or ask your doctor to send them to us. These can help your radiologist compare previously scans to the current scan.
  • Please be on time so we can ensure your appointment goes smoothly.
  • For diabetic patients only: Prior to your scan, be sure to take your oral medications as prescribed to keep your blood sugar within normal ranges. If your blood sugar is above 200 mg/dl, we may not be able to perform your scan. If you are insulin dependent, don’t take insulin within 2 hours of your scheduled appointment. Once the scan is finished, you can take insulin as needed.
