Positron emission tomography (PET)
There are a number of different tests that our PET Department does. For your convenience we have posted many informative pages on just exactly what each test and scan does and how to prepare for them.
What is this test?
This scan is performed to evaluate suspected prostate cancer spread prior to therapy or suspected recurrence based on rising blood PSA levels.
If you have any changes to your insurance, please call Registration at 866-309-0832 before your appointment. This will lessen delays and the need to reschedule your test, as many radiology services require pre-authorization.
If you cannot do the prep listed below, you may not be able to have the test, or it may need to be rescheduled.
If you cannot keep your appointment or if you have questions about these instructions, please call the P.E.T Center at 319-356-4100.
Getting ready for your test
Before your test, tell your doctor or nurse if:
You have a fear of closed-in places or if you are very nervous. We can give you a medicine to help you relax. You will need a licensed driver with you before we can give you this medicine.
Eat and drink as normal. Drink enough water so you are well-hydrated.
If you have any other test today where you are told not to eat or drink for a longer amount of time, follow those instructions.
You may take your usual medications with water before the test.
What to expect
You may be in the PET Center for 2 to 3 hours. You will wait in a room for 45 minutes before being scanned by the camera. The scan will take 30 to 45 minutes. During the test, we will put a small amount of radioactive tracer into your vein through an intravenous catheter (IV).
After the test you may
Do your normal activity.
