How Does Nicotine Affect A Pet Scan?

Can you smoke before a PET scan?

Before Your Scan

Please fast for six hours before your PET scan (no food or liquids, except water).

Please do not smoke for two hours before your scan.

Take all of your regular medications the day of your appointment, with water only.

If you are diabetic, you will receive special instructions before your scan.

Why can’t you smoke before a CT scan?

No! Smoking does permanent damage to the lungs, so the increased risk of lung cancer never totally resolves. A CT scan cannot diagnose lung cancer, but it can show abnormalities that might be cancer. Positive scans are rare but they do occur.

Can you wear a bra during a PET scan?

You need to wear comfortable, loose clothing, and will generally be changed into a hospital gown. It is important that you are not wearing metal, including jewellery, watches, zips and bra hooks, as these can affect the quality of the images produced.

Can you wear makeup during a PET scan?

Preparing for a PET / CT scan

Remove all makeup prior to the exam. You may be asked to wear a hospital gown during the exam or you may be allowed to wear your own clothing. You can continue to take regular medications.
