Undergoing a routine c-t scan could be anything but -- a new study finds the amount of radiation administered varies dramatically.
Researchers at the University of California San Francisco estimated the radiation exposure linked to eleven common CT procedures. They found radiation doses were higher than expected -- in some cases the exposure was 13 times higher than other patients experienced undergoing the same procedure.
Experts estimate the increased exposure raises the risk for cancer -- they say one in 270 women who had a CT scan of their heart will develop cancer from the procedure.
The researchers say more needs to be done to standardize c-t scans -- especially since the procedure is becoming more popular among healthy people -- the increased cancer risk may outweigh the benefit of the scan.
The study showed the median effective dose delivered through one CT scan was equivalent to 74 mammograms or 442 chest xrays.
Before undergoing a scan, ask your imaging clinic about its equipment and certifications. Park West Imaging has Pueblo's most advanced outpatient CT capability.
Results of the study at published in the Archives of Internal Medicine.
