A4.4 Prudent Use Statement
Although no confirmed bioeffects on patients caused
by exposure from present diagnostic ultrasound
equipment have ever been reported, the potential
exists that such bioeffects may be identified in the
future. Therefore, the ultrasound should be used
prudently. High levels of acoustic output and long
exposure time should be avoided while acquiring
necessary clinical information.
