What is heterogeneous in echotexture?

In echotexture, "heterogeneous" refers to an uneven or varied composition of tissue characteristics within an organ or structure as observed on ultrasound. This variability can indicate the presence of different types of tissues, lesions, or abnormalities, as opposed to a uniform echotexture, which typically suggests homogeneity. Heterogeneous echotexture may be associated with conditions such as tumors, cysts, or inflammation, making it an important factor in diagnostic imaging.
