Hello all. My mother is in stage IV nscls. I am taking her to the hospital tomorrow for another PET scan. This will be the first one I have been to with her. I just wanted to know the details about the scan. How long does it take? Will it hurt her or make her sick? Is the head included in the scan? Any info is greatly appreciated. Thank you

In a week I have my third PET scan.

It takes about 30 minutes for the fluid to go into circulation, when you are kept in a special room, then 15 to 20 minutes the scan as such, then again 30 minutes in a special room.

No negative effects. One feels very hot for an hour after the scan.

Precaution: empty stomac (you can drink water), avoid carbohydrates the evening before. Stay away from pregnant women (you are radioactive) for the rest of the day.

They normally don't do the brain because it naturally metabolyzes glucose, therefore they can't see much.

Good luck.

Whenever I have had PET scans (and I have had quite a few since 2002)...all I need to do is not eat from midnight until after the appointment, drink 1 hr before appointment liquid they provide and then another bottle 1/2 before scan.

I have an IV put in so they can inject the radioactive material. Once it is injected I have to wait 45 minutes, then the scan takes about 30 minutes and then I'm off and running

Drinking fluids after the scan helps to get the material out of your body faster.

Never felt flushed or had any adverse side effects.

Hope this helps,

Ricki

My experience has been the same - after testing to make sure your blood sugar levels are okay, you are given an injection of a glucose tracer. Then, you sit in a quiet, darkened room for 30-45 minutes while the tracer circulates. The PET scan itself takes about 20-30 minutes. The device looks about like an MRI machine. You are slid back and forth on a table into the 'tunnel'. I try to get an appt as early in the morning as possible since you can't eat after midnight. Unless your mother has claustrophobia, she should not be uncomfortable. I've never had the hot feeling described - just ready for breakfast!

Dear Dothedemom,  it is an  overall painless test.  most likely a radiation contrast will be injected prior to the test.  you usually wait 1 hour in a private setting and the scan usually last 1 hour depending on the test and all the locations being scanned. Be assured the test is nothing to be worried or concerned.  been there and done that.   wongwey
