Frequently Asked Questions
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 :
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.
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.
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.
