A member asked:
Is it common to do a ct chest scan for shortness of breath and cough that hasn't gone away for a while? i'm also worried about radiation risks

Yes: It is reasonable to use this test and exclude a number of potential diagnoses simultaneously. You are appropriate to be concerned about the radiation risk but it actually is not too bad. On average it is about two times the natural radiation you are exposed to every year just walking around on earth. Here's a tool to look at. http://www.xrayrisk.com/calculator/select_study.php?id=18
