I would think your doctor or airline would be the ones to ask

Unless something has drastically changed, a CT scan is a non invasive procedure isn't it? On the other hand your underlying condition may be the thing to worry about. Ask your doc for medical advice, not a bunch of random internet strangers.

Surely it is your doctor you should be asking?

I see now that your question got posted twice on the forum. Some internet glitch I guess. Let me just copy my reply from the other one.

I found this online:

Quote: "If you plan to travel by airplane within a few days of your PET/CT scan, make sure to inform your physician. It’s possible the glucose could set off radiation detectors at the airport. Your doctor can provide you with a card that explains that you have recently undergone a PET/CT scan."


It's the last paragraph there.

So it's safe for you, but you may want to have a doctor's note.

A standard CT (CAT) scan has no impact on your fitness to fly.

of course it wont ! it is just a form of x-ray, and no more problematic than visiting the doctor the day before !

but....as mentioned in #2, if you have a condition that required the scan, have you told your travel insurer about it? your insurance could be invalidated for travelling with an existing problem.

" It’s possible the glucose could set off radiation detectors at the airport." I believe the radioactive sugar (FDG) is only part of a PET, not a CT. Also, it has a very, very short half-life (109.7 minutes).

But do check with your radiologist.

I would at least wait for the results of the scan. I know it's an extreme case, but my GF had a scan a couple of years ago that found an Aortic Aneurism and required almost immediate emergency surgery.
