When is this available at MCHHS?
The mobile PET/CT is available every other Friday, times vary depending on work load at previous hospital on their mobile route. The exams are scheduled through your physician.
What happens during the exam?
When you check in for the exam, a technologist will escort you to the mobile PET/CT trailer, where you will rest comfortably in chair for a brief period. After resting, your glucose level will be tested. Then you will be given an injection of a radioactive isotope tracer. It will take about 30-40 minutes for the tracer to be absorbed by the body. During this time you are asked to relax in a recliner.
You will then be asked to lie down on the scanning table. It is very important to remain still during the procedure, because any movement can interfere with the results.
A special camera detects the isotope tracer throughout the body, and a computer translates the signals into an image.
Are there any risks?
There are no known risks from the isotope tracer that is used in PET/CT.
You should feel no discomfort from the tracer or the exam itself and there are no risks to anyone around you.
PET/CT scans are not considered safe for women who are pregnant, so please let your physician know if you are or may be pregnant or if you are breastfeeding.
What’s the preparation for the test?
Please arrive at the hospital at least 20 minutes before your appointment to be checked in for your procedure.
You will be asked to not eat, or drink anything but water for at least four hours before the scan. This is to help the isotope tracer absorb in the body properly.
You may be given some medicine to help you stay quiet during the scan and/or to reduce our bladder activity.
Will I be able to feel the scan?
No, you should not feel anything during the scan, except the minor discomfort from the injection of the isotope.
How long does the test take?
It will take a total of 60-90 minutes from the preparation to the end of the exam. You may immediately go back to your normal daily routine.
