also applies to endoscopic, transvaginal and transcutaneous applications. When tissue/gas interfaces or contrast agents are present, ultrasound exposure levels and durations should be reduced to the minimum necessary to obtain the required diagnostic information.
WFUMB Symposium on Safety of Ultrasound in Medicine: Published Recommendations on the Safe Use of Ultrasound (1998) The following is a selection of existing published recommendations that were approved by the WFUMB Executive Council in March 1997 and published in 1998, which are relevant to the safe use of ultrasound contrast agents in diagnostic ultrasonography. For more detail, refer to World Federation for Ultrasound in Medicine and Biology Symposium on Safety of Medical Ultrasound; Conclusions and Recommendations regarding thermal and nonthermal mechanisms for biologic effects of ultrasound. (Ultrasound Medicine Biol 1998;24(S1):1–55).

When tissue/gas interfaces or contrast agents are not present, and where there is no risk of significant temperature elevation, the use of diagnostic Doppler equipment need not be withheld because of concern for ultrasound safety. When any of the above conditions might be present, ultrasound exposure levels and durations should be reduced to the minimum necessary to obtain the required diagnostic information.

Recommendations: Non-Thermal Effects ●
It has been shown experimentally that acoustic cavitation can alter mammalian tissues. It is therefore important to consider its significance in medical applications of ultrasound.

● Contrast Agents Gas bodies introduced by a contrast agent increase the probability of cavitation. A physician should take this into account when considering th e benefit/risk ratio of an examination. ●

B-Mode Imaging
When tissue/gas interfaces or contrast agents are not present, the use of B-Mode imaging need not be withheld because of concern for ultrasound safety. This statement
