Patients perception of ionising radiation risks in CT ionising exposure. Does dose bill works?

Communicating to patients the magnitude of risk related to ionizing radiation exposureis problematic because of the uncertainty in estimates derived principally fromepidemiological studies of large populations [1-6]. Euratom directive 59/2013 requiresthat dose bill will be part of the radiological report in European Countries [7]. However,how a risk is framed has a profound effect on risk perception. To date, no previous studiesevaluated which could be the best way to make patient friendly dose bill. Our aim wasto evaluate patients' perception of radiation exposure related to routine CT and theirunderstanding after dose bill.
