What to expect when you at arrive University of Colorado Hospital for your PET/CT scan
When you arrive, we will test your blood glucose level to ensure that is within the normal range (60 to 100). If you have diabetes, please tell the scheduler when they call to schedule your exam.
Once we know that your blood glucose is at the right level, we will inject the isotope through an IV in your arm. You will also be asked to drink an oral contrast. The oral contrast and the isotope are what the scan will be reading.
After your injection, the solution needs to flow through your body. You will relax in the patient prep are for at least one hour. You may want to bring a personal music system to listen to music while you relax.
You should plan on being with us for a total of about 2 hours. In some instance we may take delayed images which may take a little longer.
