How much radiation is there in cat scans?

I've been referred to get one for my sinus headaches and I'm anxious to do so because of the radiation. Any suggestions?

"The effective radiation dose from this procedure is about 0.6 mSv, which is about the same as the average person receives from background radiation in two months."

http://www.radiologyinfo.org/en/info.cfm...

" How much radiation was I exposed to for the CT sinus exam? The effective dose is around 100-200 mrem. The risk for lifetime fatal cancer due to radiation exposure is estimated to be 4 in one million per 1,000 mrem. This can be compared with the general lifetime fatal cancer estimate of 1 in 4 or 5 of dying of cancer; this translates to 200,000 per million."

The benefit of a CT scan of the sinuses greatly outweighs the risk. The benefits include a correct diagnosis, which will help your doctor treat you.

I have never used a contrast (dye) for a routine scan of the sinuses, by the way.

I can't tell you specifically how much radiation, but I can tell you that it 's not enough to wrorry about. I've had at least 5 cat scans (Which btw aren't scary at all), and no one was ever concerned with how many I've had before. So don't stress about it. I hope you get your sinus problems fixed up. Good luck!! :)

here try this ,, call your local hospital and talk to tech in radiology,,and see if they know,,,

The effective radiation delivered is 10 mSv, equal to the amount of "background" radiation a person would receive in about three years. If not being studied, the abdomen and pelvis are protected with a lead apron. A small risk of allergic reaction to iodine (used as a contrast material) exists, but imaging centers are equipped to deal with it.

Other Then That Ct Scans Are no big deal they are simple and easy I have had 10-12 in the last 5 years.
