Echogenicity in ultrasound refers to the ability of tissues to reflect ultrasound waves, which is critical for creating images. It is typically described using specific terms that characterize relative echogenicity compared to surrounding tissues. Terms like hypoechoic, isoechoic, and hyperechoic are standard in ultrasound reports.

- Hypoechoic describes tissues that reflect fewer ultrasound waves and appear darker on the image compared to adjacent structures.

- Isoechoic indicates that the tissue has a similar echogenicity to its surroundings, making it difficult to differentiate based on echogenicity alone.

- Hyperechoic refers to tissues that reflect more ultrasound waves, appearing lighter or brighter on the scan.

These terms provide clear, descriptive information about the tissue’s characteristics, aiding in the interpretation of findings. This standardized nomenclature is essential in clinical settings for effective communication among healthcare providers about diagnostic results.
