2/6/2024 0 Comments Overexposed x rayTherefore, if the radiation risk associated with a specific level III procedure (individual patient) exceeds the expected benefit of an examination or intervention, it is not justified.įrom the point of view of radiation protection, unjustified examinations should be avoided, but not necessarily be understood as accidental or unintended overexposure in the sense of the EU-BSS. Interventional procedures for example involve the risk of unpredictable complexity with dose levels higher than intended. An abdominal CT of a child with focal liver lesions would not be justified at level II.Īt level III, the application of a specific procedure to an individual patient should be justified, taking into account the specific objectives of the planned exposure and clinical conditions of an individual patient. Level II justifications are published in national and international referral guidelines and should be evidence-based. For example, an abdominal CT is justified at level II for patients showing symptoms of an aortic aneurysm with rupture, while it is not justified for a child with focal liver lesions. The aim of level II justification is to judge whether the radiological procedure will usually improve the diagnosis or treatment of patients with similar clinical conditions. Justification applies at three levels in the use of radiation in medicine.Īt level I, the use of ionising radiation in medicine is generally accepted as doing more good than harm to the patient.Īt level II, a specified procedure with a specified objective is defined and justified. The responsibility for the justification of the use of a particular procedure falls on the relevant medical practitioners. Medical exposures are unavoidable since ionising radiation is used in many procedures to diagnose or treat patients, providing benefits usually larger than the risk associated. The principal justification of medical exposures is to do more good than harm to the patient.
