Which item is NOT listed as a contraindication to ultrasound?

• A. Heart
• B. Eyes
• C. Skull
• D. Genitals

Answer: (A)

The main idea is understanding where ultrasound therapy should not be used because of safety concerns about tissue heating and energy focus. Areas with high sensitivity or structures that can be easily damaged—like the eyes, skull, and genitals—are typically listed as contraindications. In addition, using ultrasound over growing bones in children (epiphyseal plates) and other vulnerable or non-ideal sites is avoided. The heart, on the other hand, is not generally listed as a contraindication in standard guidelines; diagnostic ultrasound imaging routinely evaluates the heart, and therapeutic ultrasound can be applied over thoracic regions when clinically appropriate and with proper settings. So the item that is not listed as a contraindication is the heart.
