Radiology and cardiovascular researchers from the Medical University of South Carolina in Charleston, S.C., today presented new data that shows the risk of cancer from exposure to radiation during computed tomography for cardiovascular disease has been overstated and that new estimates are several times lower than previously published conclusions. The MUSC researchers presented their findings at the American Heart Association's meeting in New Orleans.
In previously published studies, different researchers concluded the risk of cancer from radiation exposure during CT for cardiovascular disease was approximately 1 in 114, but the new study suggests the risk is 1 in 1000.
U. Joseph Schoepf, MD, and colleagues from MUSC, claim previous studies assessing lifetime risks of cancer from radiation in cardiac CT are based on unreliable models of patients who undergo CT for cardiovascular disease.
