Hypoechoic

In general imaging ultrasound, “hypoechoic” describes tissues or structures that appear darker than surrounding areas on an ultrasound image. This reduced brightness indicates that these tissues reflect fewer sound waves back to the transducer. Hypoechoic lesions often suggest a lower density or a higher fluid content compared to adjacent structures, such as solid masses, cysts, or inflammation. Understanding hypoechoic characteristics is crucial for accurate diagnosis in various medical imaging applications.
