Echogenicity
the ability to produce an echo or reflections of the sound beam
Echogenic
containing structures that reflect high-frequency sound waves; a structure or medium that is capable of producing echos
Hyperechoic
denoting a region in which the echoes are stronger or brighter than normal or than the surrounding structures; the opposite of hypoechoic
What’s the difference between hyperechoic and echogenic?
NOTHING!
Hypoechoic
a region in which the echoes are weaker or less bright or fewer than normal or surrounding regions; the opposite of hyperechoic
Isoechoic
having the same relative echogenicity as a surrounding structure
Anechoic
without echoes; used in terms of characterizing an organ or a mass when compared to the parenchyma around it
Heterogeneous
non-uniform; irregular, composed of mixtures of different kinds
Homogeneous
uniform; composed of the same element
Cystic
without echoes; will have smooth, well-defined borders, and posterior acoustic enhancement; used in terms of identifying abnormalities
The bladder is (cystic/anechoic) compared to the uterus, but a mass on an organ is (cystic/anechoic).
anechoic; cystic
Solid
echogenic shades of gray that represent internal tissue composition
