How do I prepare for my scan?
Please inform your physician if you think there is a possibility that you might be pregnant or if you are breast feeding before you schedule your PET/CT study. Most importantly, inform our Radiology Technologist / Nurse before you receive the radioactive tracer.
Please do not have anything to eat or drink for 6 hours prior to your appointment (except water). We encourage you to drink plenty of water both before and after the scan (approximately 4 to 5 glasses), as this helps to flush the tracer we administer through your body. You may continue to go to the toilet as usual prior to your scan.
Will I need an injection?
In order for us to obtain images of your body, we need to give you an injection of radioactive tracer into a vein – usually your arm. This is similar to a blood test. There are no side effects from the injection and it will not make you feel any different. After receiving the injection you will need to rest and remain lying down for 1 hour while the injection is absorbed into your body.
What can I expect during my PET/CT study?
Once the radioactive tracer has been absorbed into the body, you are ready for your scan. In the scanning room, you will be asked to lie down on your back on the scanning bed. The bed will move through the ring of the scanner and collect images for between 30 to 60 minutes, depending on the type of scan that you need.
How safe is PET/CT?
The amount of radiation in the tracer and is equivalent to the radiation you are exposed to when you have an x-ray. The benefits of the scan far outweigh any potential risk from the radiation. The tracer will not produce any side effects. In particular, it will not make you drowsy and you will be able to drive after your appointment.
When will I get the results?
The results of your scan will be sent to your referring Physician within 24 hours of your exam. Your report and images will include a summary of the radiologist’s findings and recommendations for further follow-up.
