Lung Damage Assessment

By William D. O'Brien, Jr. and James F. Zachary.

It has been long thought that diagnostic ultrasound equipment could not produce biological damage. However, this assumption is now not the case. Diagnostic ultrasound-type pulses at diagnostic pressure levels have produced significant damage (lung hemorrhage) in mice, rats, rabbits, and monkeys. The majority of this experimental work was conducted with a commercial diagnostic ultrasound system. Thus, the questions of paramount clinical significance are: 1) Does diagnostic ultrasound produce lung damage in patients and, if so, 2) under what exposure conditions does the damage become significant? The medical significance of the research is related directly to the assessment of a potentially serious human health risk that may now be occurring in infants, children and adults from the use of current diagnostic ultrasound equipment. The research has been designed to address directly these issues by an interdisciplinary group of investigators who have considerable experience with ultrasound-induced lung damage, lung morphology and lung function research studies, in addition to ultrasound biophysics and engineering.
