International guidelines and regulations for the safe use of diagnostic ultrasound in medicine

This paper presents a brief update on ultrasound bioeffects. The benefits and risks of ultrasound examinations and the concept of ALARA, i.e. exposure As Low As Reasonably Achievable, are introduced. Output display standard (thermal and mechanical indices) provides information on the potential for bioeffects helps to implement ALARA easily and efficiently. Some key aspects of guidelines and regulations from major ultrasound organizations are highlighted, these offer valuable information to help users apply diagnostic ultrasound in a safe and effective manner. Although harmful bioeffects may be detected in the future, current data indicate that the benefits to the patient of the prudent use of diagnostic ultrasound outweigh the risks, if any, that may be present. It is important to create awareness of risk and developing safety culture among practitioners. Continuing education is needed to ensure that appropriate risk/benefit assessments are made based on current knowledge and pave the way for self-regulation.
