Scan beneficiary calculated

hi my name is aimy Hara and I'm an associate professor of radiology at the Mayo Clinic in Arizona and what I want to talk to you today is about radiation dose with CT scans now a CT scan is a common procedure that we do every day there's about 65 million of these examinations performed every year in the United States so this is a test where you lay on your back on a table usually have an IV and insert it into your arm that gives you contrast during the procedure and you hold your breath while the table is slid through a doughnut sized hole opening and pictures are taken anywhere from head to toe so we do this examination to look for a lot of different tests like stroke diverticulitis appendicitis renal stones bowel obstruction cancer until look at cancer spread so as a lot of different uses recently in the publicity and media there's been a lot of attention concerning radiation dose with CT so there have been headlines such as CT scans can cause cancer that I believe caused a lot of widespread fear in the public and it's important to separate fact from fiction when we talk about this argument so a lot of the media publicity came after an article that was published in a prestigious medical journal that said that was a theoretical increased risk of cancer from CT scans and it's important to know that this article was based on a theoretical risk so there's actually never been a patient who's had a CT scan that then got cancer because of that CT scan or any studies have really shown that CT scans cause cancer but that this article was based on risk associated with radiation exposure that was based on atomic bomb survivor data so a lot of people in the medical community really believe that the fundamental basis of this article was flawed because the radiation exposure blast that you get from an atomic bomb is obviously very different from small radiation exposures that you get from imaging over several years so a colleague was talking about this with another patient the other day and said it's similar to a few walking across the carpet and you get those little electric shocks versus sticking your finger in an electric socket you know those are two very different things and that's similar to the analogy that they're kind of making in this paper that one is similar to the other but in any event I think that the paper raised important choose that one CT scans are being done more and more commonly today and there is a small but real risk of the radiation exposure with CT scans so I'm going to talk a little bit about the numbers because I think it helps to put in perspective exposure from CT scans versus other types of exposure that we see every day so just from walking around in...
