Abstract:
Despite criticism, there is no way out from cumulative effective dose (CED) when several organs are involved, and we have to focus on the patient’s radiation safety in addition to the technique dose. One cannot close eyes to stochastic risks when patients are receiving cumulative doses in three digits of mGy of organ doses or three digits of mSv of CED in a short period of a few years. Scientists involved in studying radiation effects inform us that we have to sum doses from imaging exams performed at different times and they do not have gap correction factors for stochastic effects. Studies published in the last 3 years have brought new results, never before known. They have opened a new era where every one of us has the potential to contribute to enhancing patient radiation safety and the manufacturers have to do much more. The talk will deal with what lies ahead, which is more powerful than controversies.
