echogenicity
number of echoes produced
echotexture
echo pattern within an organ or structure
echogenic
relative term
a structure that produces echoes
anechoic what, AKA (2)
without internal echoes
echolucent, sonolucent
hyperechoic
increased number of echoes
compared to adjacent structure
hypoechoic what, aka (2)
fewer echoes in a structure compared to another structure
echopenic, echo-poor
isoechoic
structure that is the same echogenicity as an adjacent area
homogenous
uniform echoes throughout a structure
describes the parenchymal texture of several organs
heterogenous
uneven texture pattern through a structure
parenchyma
