echogenicity

(redirected from Echogenecity)

echogenicity

/echo·ge·nic·i·ty/ (-jĕ-nis´ĭ-te) in ultrasonography, the extent to which a structure gives rise to reflections of ultrasonic waves.

echogenic

(ek″ŏ-jen′ik) [ echo + -genic]
Capable of producing echoes, i.e., of intensely reflecting sound waves rather than transmitting them.
echogenicity (-jĕ-nis′ĭt-ē)

echogenicity

the characteristic ability of a tissue or substance to reflect sound waves and produce echoes. Bone and gas are most echogenic and fluids such as urine and bile the least. Organ parenchyma and soft tissues are intermediate, but each differs slightly from the other and relative characteristics are known.
