What is Positron Emission Tomography PET)?

PET, or "Positron Emission Tomography" is a state-of-the-art imaging technology that uses small amounts of radioactive pharmaceuticals (radioisotopes) to make images of the human body or disease process. Most procedures use a glucose (sugar) labeled with a short-lived radioactive material. Unlike, conventional CT, MRI, or X-ray, PET scans provide "functional" or "metabolic" information of organ tissues. Obtaining this "functional" information gives the physician an excellent tool in :

  • Diagnosing both the presence and extent of disease.

  • Determining the appropriate methods of treatment or therapy.

How long does the procedure take?

The total time required will be 2 - 3 hours. After the injection of the radiopharmaceutical, you will wait up to one hour in a comfortable environment for the material to circulate in your body. The whole body imaging procedure will take 45 min. - 1 hour.

How do I prepare for the procedure?

  • You SHOULD NOT eat or drink anything but water for 4 hours before your exam.

  • Medications can be taken on your normal schedule unless your physician has directed you otherwise.

  • Special considerations are made for diabetic patients regarding diet, insulin, and procedure preparation.

  • Please wear comfortable, warm clothing since the scan area is maintained at a cool temperature for the equipment. In most situations, clothing will not need to be removed.

  • Please bring your current health insurance ID information as well as any other radiology exams (i.e., CT, MRI, X-ray) that you have been instructed to bring.

  • Sedation is needed for certain exams.

  • You will be instructed to bring a family member or friend to drive you home if sedation is required.

Are there any side effects?
The radioactive pharmaceutical you will receive is very safe and there are no known side effects. There is limited radiation exposure involved that is similar to other Nuclear Medicine or Radiology procedures.

Who will be performing my exam?
East Texas Open MRI & Diagnostics prides themselves on maintaining highly competent, well trained technical staff. An experienced Nuclear Medicine technologist who will work closely with the radiologist and clerical staff to provide the highest quality service possible will perform your procedure.

How is the scan performed?
A short-lived radiopharmaceutical, specifically designed for use with PET imaging, will be injected into your arm. The procedure will begin after an "uptake period" of 45-60 minutes depending on the type of examination being ordered. There are no side effects from the injection and you will be asked to rest quietly during the "uptake period." The scan itself will take approximately one hour.

You will be asked to lie comfortably on the imaging table while the scanner detects the concentration of the glucose within the body and generates an image by use of the computer. The amount of time involved to complete your scan will depend on the type of procedure your physician has ordered. The PET staff will provide you with this information at the time of your scan.

Who interprets PET scans?
After completion of the exam, the technical staff will "process" the information and prepare it for review. A radiologist, with extensive training and experience in the field of Radiology/Nuclear Medicine, will use a computer to analyze the images.

When will the results be available?
After completion of your exam, the technical staff will "process" the information and prepare it for interpretation. A radiologist with training and expertise in the field of PET and other correlative imaging studies will interpret the images the following day. A typed report will be forwarded to your physician within 1-2 days.
Note: It is important that we have your outside films at the time of the PET scan in order to issue the report in a timely manner.
You MUST obtain your results through the physician that ordered your exam.
