This brief review addresses the issue of health and safety from exposure to diagnostic ultrasound. The exemplary historical record of diagnostic ultrasound exposures is coupled with great patient benefit. However, the power outputs of clinical devices have been increasing over the past decade such that inertial cavitation seems reasonably likely to occur if appropriate gas nuclei are present. The use of microbubble contrast agents for certain diagnostic procedures ensures a well nucleated system. Under such conditions, the use of low signal output levels and short exam times will decrease the chance of cavitation related bioeffects.
