Adipose tissue has what effect on ultrasound?

• A. Great
• B. Little
• C. Moderate
• D. Significant

Answer: (B)

The main idea is how tissue properties affect ultrasound waves. Ultrasound energy is lost (attenuated) and reflected at interfaces depending on tissue density and sound speed. Adipose tissue has a relatively low attenuation and only a modest impedance difference from surrounding soft tissues, so the beam travels through with minimal energy loss and little distortion. In practice, a layer of fat can slightly affect depth measurements and image brightness of deeper structures, but it doesn’t substantially hinder the beam. That’s why adipose tissue is described as having little effect on ultrasound. More pronounced effects come from bone, air, or very dense tissues, which cause significant attenuation or reflection.
