1 Ιουλ 2013 · Based on such data, a 2006 report from the National Research Council has estimated that exposure to 10 mSv—the approximate dose from a CT scan of the abdomen—increases the lifetime risk of...
30 Νοε 2022 · Based on 111.6 million adult participants from 3 continents (Asia, Europe and America), this meta-analysis identifies an inordinately increase in cancer risks from CT scans for adults. Moreover, the cancer risks were positively correlated with radiation dose and CT sites.
Two epidemiological studies revealed the risk of CT scan exposure before the age of 19 years increased the risks of leukemia, brain cancer, and all cancer types including leukemia and NHL (13,21). However, studies documenting the risk of medical radiation exposure in adults with cancer are scarce.
1 Νοε 2012 · Ten years after the suggestion that CT scans might produce a small cancer risk, Pearce et al have shown that this is almost certainly the case, and they have confirmed the numerical magnitude of the risks; more complete epidemiologic studies are needed and several are indeed in progress, but in the interim, estimation of medical radiation risks ...
In the 12 years after a single CT scan, the risk of cancer was about 1–2 cases for every 10,000 scans performed on children and young people. In talking with health care providers, three key questions that parents can ask are: Why is the test needed? Will the results change the treatment decisions?
10 Οκτ 2021 · In conclusion, there is growing evidence from epidemiological data that CT scans can cause cancer. The absolute risks to individual patients are, however, likely to be small. Ongoing large multicenter cohorts and future pooling efforts will provide more precise risk quantification.
CT scan is short for computerized tomography scan. CT scans are a type of X-ray that provide highly detailed images. Some fear that the ionizing radiation emitted from CT scans can harm DNA and cause tumors. But the risk associated with these tests is worth the benefit, in most cases.
