Raleigh Radiology and WakeMed are teaming up to introduce a new PET/CT Scanner, offering the most advanced technology to help physicians detect disease and better understand disease progression for accurate and early treatment decisions.

The Siemens Healthineers Biograph Vision is the latest, next-generation of PET/CT scanners that utilizes artificial intelligence (AI) and advanced imaging to detect even the smallest lesions with less exposure to radiation. It offers short scan times and a wide bore for patient comfort.

The fusion of the two technologies in a PET/CT scanner provides a wide range of benefits, including:

  • Eliminating the need for invasive procedures or surgeries such as painful biopsies or other procedures.
  • Providing early diagnosis since PET/CT can show pathological changes earlier than they would show up on CT or MRI alone.
  • Providing accurate disease staging and location for biopsy, surgery or treatment planning.
  • Assessing response to and effectiveness of treatment, which can help providers make informed therapy decisions.


Raleigh Radiology’s nuclear medicine team has decades of expertise in PET/CT technology. Our team includes eight board-certified radiologists with experience in interpreting PET/CT studies, and is supported by expert technologists who are highly-trained in PET technology.



For 24 hours prior to your procedure

  • Do not engage in any strenuous activities. This includes manual labor, yard work or exercise to include jogging, lifting weights, etc.
  • Eat a low carbohydrate, no sugar diet (avoid starches, pastas, breads, rice, beans, fruits, candy, mints, gum and caffeine).

On the day of your scan

  • Do not eat or drink anything (other than water) for 4-6 hours before your test. This includes coffee/tea, soda, food, gum or mints.

  • It is important that you’re well hydrated for the test, so drinking water beforehand is encouraged.

  • Continue taking medication as prescribed.

  • Come dressed comfortably in warm clothing – ideally that has no metal (zippers, snaps, etc.) If you forget, we are happy to provide a gown or scrubs to wear during your test. Please also refrain from wearing jewelry and metal hairpins as they may affect the quality of the CT 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 better interpret your scan by comparing it to those done previously.

  • We ask that you please arrive for your appointment on time. This helps ensure your appointment goes smoothly for you and for our other patients throughout the day.

  • For diabetic patients only: Prior to the procedure, please take your oral medications as prescribed to ensure your blood sugar stays 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, do not take insulin within 2 hours of your scheduled appointment. Once the scan is finished, you can take insulin as needed.


When you arrive, you’ll find a self-registration kiosk in our lobby that allows for easy, touchless check-in. If you need assistance, we have plenty of support staff available to help.

  • You’ll be greeted by one of our highly-trained molecular imaging technologists who will explain the test and what to expect.

  • Next, you’ll be given a glucometer test (finger stick) to check your sugar levels to make sure they’re in the normal range (below 200 mg/dl).

  • Your technologist will administer a small injection of radioactive tracer (commonly known as FDG) intravenously. The injection has no known side effects and is not allergenic.

  • In some instances, you may also need CT contrast administered (either orally or via IV) – depending on the test your physician ordered.

  • After the administration of FDG, you’ll be escorted to our comfortable “Uptake Room” while we wait for the tracer to circulate through your body. This typically takes approximately one hour. We’ll provide you with a comfortable chair, a warm blanket and a bottle of water to ensure you’re well-hydrated for your exam. For the best quality scan, we ask that you avoid movement to include talking, reading or even using electronic devices such as cell phones, tablets, etc. Because the tracer gravitates toward areas of activity within the body (including the brain), we encourage you to just rest your eyes and relax during this time. The Uptake Room is fitted with audio and video monitoring equipment should you need to communicate with your care team for any reason. We’ll use this to keep in touch throughout your uptake process.

  • When your uptake is finished, we’ll encourage you to stop by the restroom on your way to the PET/CT scan room where we’ll meet you to complete your exam. In most instances, the scan takes approximately 15 minutes. Your technologist will be with you throughout the test, monitoring from the control room. Depending on what your physician ordered, some scans may require subsequent imaging.

  • On average, your entire appointment from start to finish should last around one and one half hours, although some tests may take up to two hours.

  • Once the scan is complete, a board-certified molecular imaging radiologist will interpret the images from your scan and your doctor will receive a detailed report of the findings. In most cases, the report is complete within 24 hours.


  • Raleigh Radiology and WakeMed are committed to reducing radiation exposure by using the lowest dose possible at all times. Our state-of-the-art Siemens Healthineers Biograph Vision scanner makes this possible by requiring significantly less injected tracer doses than other current technologies.

  • Our team is comprised of board-certified, molecular imaging radiologists with decades of experience. Our PET/CT physician team is supported by expert technologists who are highly-trained in PET technology.

  • As always, our goal is to make your experience as comfortable as possible. If you have any questions or concerns about your appointment, please call us at 919-350-4210.
