Frequently Asked Questions
Is a PET scan safe?
Yes, the radiation dose from the tracer is carefully controlled and considered safe for diagnostic use, though pregnant women and young children require special precautions; discuss any concerns with your doctor.
How should I prepare for a PET scan?
You will usually need to fast for 4-6 hours beforehand, avoid strenuous exercise the day before, and inform the technician if you have diabetes, as blood sugar control affects image quality.
How long does the whole appointment take?
Including the tracer uptake waiting period, the full appointment typically takes 2-4 hours, though the actual scanning itself takes only 20-30 minutes.
When will I get my results?
A nuclear medicine specialist typically reads the scan and results are usually available within 24-48 hours, which your referring doctor will then explain to you.
Do I need to avoid other people after the scan?
Yes, it's advisable to avoid close, prolonged contact with pregnant women and young children for several hours after the scan since trace radioactivity remains in your body briefly.
