PET/CT 

Positron Emission Tomography (PET) and Computerized Tomography (CT) are two tests that are often used together to evaluate problems within the body. The PET portion assesses the physiological, or metabolic activity within the body while CT is used to define anatomy structures within the body.

These tests are most often used to precisely pinpoint the location of, and to characterize, cancer. Having two scans in one session is more convenient for the patient, and it provides the doctor with the information they need to make a proper diagnosis and recommend treatment.

A PET/CT usually takes about 30 minutes.

Preparation Instructions

You will receive instructions prior to your exam either by your physician or from our office. Arrive at least one hour before your scheduled scan time to allow for an intravenous injection of a special radiotracer. Do not consumer anything except water before your appointment, as it can interfere with your test results. Also, avoid exercise and physical activity on the day of your exam.

What to Expect

We will test your blood sugar levels prior to your exam. Approximately one hour before the exam, you will receive a special radiotracer by intravenous injection. This requires time to travel through your body, where it will become absorbed by the organs or tissues being imaged.

You will be asked not to move or talk during the scan. The technologist will communicate any instructions with you via an intercom. After the scan, you can resume normal activities, including driving and eating, unless instructed otherwise. Drink plenty of fluids the rest of the day to help expel the radiotracer from your body.

You are advised to stay at least 10 feet away from anyone who may be pregnant, or children under 18 years of age, for a full 24 hours after your exam.
