What does the term "hyperechoic" indicate during an ultrasound examination?

The term "hyperechoic" refers to tissues or areas within the body that produce more echoes compared to the surrounding tissues during an ultrasound examination. This increased echogenicity is typically caused by the density and composition of the tissue; for example, structures like the liver or gallbladder may appear hyperechoic compared to surrounding fluid-filled spaces. Hyperechoic areas tend to appear brighter on the ultrasound image, which can help in the identification of certain types of lesions, calcifications, or fatty infiltrations.

Understanding the concept of hyperechoic is crucial for differentiating various tissues and structures during an ultrasound, as it aids in diagnostic interpretation by highlighting areas of interest due to their enhanced echo return.
