What significant risk should be considered with high-intensity ultrasound?

High-intensity ultrasound can produce a significant risk associated with tissue heating or damage. This is primarily because high-intensity ultrasound waves generate heat as they pass through biological tissues. The energy from these sound waves can be converted into thermal energy, leading to an increase in temperature within the target tissues. If the intensity of the ultrasound is sufficiently high, it can cause thermal effects that may result in cellular damage or necrosis. This risk is particularly pertinent in therapeutic applications where higher intensities are often used to achieve desired outcomes, such as breaking down gallstones or treating certain tumors.

In addition to thermal effects, high-intensity ultrasound can also cause mechanical effects, such as cavitation, where bubbles form and collapse within the tissue, potentially leading to further damage. Awareness of these risks is crucial for healthcare professionals performing ultrasound-based procedures, ensuring they adhere to safety guidelines and protocols to minimize any adverse effects on patient tissues.
