Echogenicity is the returning of a signal in ultrasound
examinations. Increased echogenicity means increased density of the
sound waves.

Echogenicity is the ability for sound waves to bounce or reflect
off a surface. Echogenicity may be low or high depending on the
content of the surface. Bone, gas, and fat have high echogenicity.
Liquids such as urine, bile, and malignant lesions have low
echogenicity.
