Benefits of PET/CT

Allergies: Notify your physician of any allergies before the exam. If you have any allergy to contrast material, or “dye,” your physician may prescribe medications to reduce the risk of an allergic reaction.

Pregnancy: Be sure to inform your physician if you are pregnant.

Medications: You will be asked about medications you are taking at time of your appointment scheduling. If you are diabetic, contact us for further instructions prior to your scheduled appointment.

 Eating: If your PET/CT SCAN is before 12:30 pm, the last meal should be no later than 9:00 pm the night before the exam. If your PET/CT SCAN is after 12:30 pm, the last meal should be no later than 6:00 am the day of the scan.

During your last meal before the exam, do not eat any carbohydrates or starches (rice, potatoes, breads, fruits, vegetables, etc.). Eat protein (beef, chicken, eggs, pork, fish) only. A low blood sugar level is essential for a successful scan. Please refrain from exercising or hard labor 24 hours prior to your scan. You can drink water anytime before the exam.

ET/CT helps physicians diagnose, stage and treat cancer with more accuracy than ever before. The exam can provide answers to critical questions:


• Where is the tumor?

• Is it spreading?

• How large is it?

• What is the optimal therapy?

• Is the therapy working?

• Is there a recurrence?

What to Expect

You will be greeted by our warm and professional staff in a spa-like environment. The technologist will escort you to a private room where you will change into comfortable attire and receive an IV line used to inject a small amount of FDG (sugar water with a radioactive tracer).

 After the injection, you will relax in the comfort of a large recliner for about one hour. The technologist will then escort you into the PET/CT scanner where your imaging exam will take about 30-45 minutes.

 Following the exam you will be offered an array of snack and drink options.

It is important that you drink water and empty your bladder often for the rest of the day. You can drive and resume normal
activities immediately after leaving the facility, unless you have received sedation.
