RADLEX synonyms : heterogeneous background; mixed background echotexture; complex background echotexture; fibrocystic background echotexture;
Definition : Heterogeneity can be either focal or diffuse. The breast echotexture is characterized
by multiple small areas of increased and decreased echogenicity. Shadowing may occur
at the interfaces of fat lobules and parenchyma. This pattern occurs in younger breasts
and those with heterogeneously dense parenchyma depicted mammographically. How and
if this pattern affects the sensitivity of sonography merits study, but technical
maneuvers may help resolve interpretive issues of true lesion versus pseudopathology.;
