CT scans, cancer risk linked Machines will kill up to 15,000 yearly December 15, 2009Posted by Dreamhealer in Big Pharma, Cancer.
Widespread overuse of CT scans and variations in radiation doses caused by different machines and different operators are subjecting patients to high radiation doses that will lead to tens of thousands of new cases of cancer and as many as 15,000 deaths for each year that the scanners are used, researchers are reporting Tuesday.
Several recent studies have suggested that patients have been unnecessarily exposed to radiation from CT scans, but two new studies reported in the Archives of Internal Medicine are the first to quantify the extent of exposure and the risks.
Researchers from the University of California, San Francisco found that the same imaging procedure performed at different institutions — or even on different machines at the same hospital — can yield a 13-fold difference in radiation dose, potentially exposing some patients to inordinately high risk.
