The term "echogenic" refers to the ability of a tissue or structure to reflect ultrasound waves, which results in a bright appearance on ultrasound images. Echogenic structures reflect sound waves more efficiently than surrounding tissues, leading to stronger signals that are recorded by the ultrasound machine. This reflection creates a brighter image on the display, allowing clinicians to differentiate various types of tissues and assess their characteristics.

In practice, echogenicity is an important concept in ultrasound imaging, as it helps in identifying normal anatomical structures and potential pathological changes based on how these structures interact with ultrasound waves. For example, fat and some types of solid organs are typically more echogenic compared to fluid-filled structures like cysts, which appear anechoic (dark) due to their inability to reflect sound waves effectively. Understanding echogenicity is crucial for sonographers in interpreting ultrasound images accurately.
