In the past year several significant institutions from California to Alabama reported over dosing patients when performing CT Brain Perfusion studies. These radiation doses were unfortunate for the patient and resulted in negative outcomes. The effect these failures may have on the future use of CT is unknown but could be far reaching when combined with health care reform and the slow economy.
This release of information comes on the heels of several articles about the effects of X-ray radiation from CT scanning and how it may add new cancer cases into our population. In a recent volume of the Archives of Internal Medicine it was reported that since 1980 we’ve gone from 3 million CT scans annually to 70 million in 2007. The same authors are projecting tens of thousands of new cancer cases will be a direct effect of the increased use of CT scanning in the general population. Why has the dose increased and why have we increased the usage of CT scanning?
