[Viability of human cancer cells in culture after exposure to diagnostic ultrasound].
Reports have appeared in the literature regarding biological damage to human cells following exposure to diagnostic ultrasound. We have examined the effects of diagnostic ultrasound (Sonel 400, C.G.R.) on human cell lines established in our laboratory. We report here that exposure to diagnostic ultrasound, at maximum exposure intensity and at exposure time as long as 60 minutes, produces no cell lysis as determined by vital dye exclusion ability, and as confirmed by electron microscopy. However, the exposure to ultrasound produced by an apparatus delivering an acoustic power higher than the diagnostic levels (Sonoscope-Alcatel) can cause the complete lysis of the same cells.
