Should i worry about amount of radiation from a ct scan for a pulmonary embolism study?

No: I'd worry more about possible pulmonary embolism which could be deadly in the short-term as opposed to excess radiation from the ct scan which would need to be repeated excessively in order to be worrisome in the long term. I suppose if the tech wasn't paying attention and the ct scanner hadn't been checked & certified, it's possible to get too much radiation but i'm more worried about pe.

Radiation concern: It is always reasonable to be concerned about radiation exposure, but you have to keep it in perspective of the risk of the disease being considered. One ct scan is not a lot of radiation, while a pulmonary embolism can cause death. The risk to benefit would favor having the ct scan.

1/1500: This is the chance of getting lung cancer. Do not worry.

No: As drs. White, lessnau, and lin all said, you risk of having an undetected and untreated pulmonary embolism is far higher than your risk from having one ct scan of your lungs.

Change: It is now estimated that 2, 500 cts induce one lung cancer.
