ARDMS (American Registry for Diagnostic Medical Sonography) Practice Test

Hyperechoic masses on an ultrasound suggest that the mass is denser than the surrounding tissues. This increased density causes the mass to reflect more sound waves, resulting in a brighter appearance on the ultrasound image. Such a characteristic is commonly associated with solid masses, such as tumors or certain types of lesions, which are usually firmer than the surrounding, softer tissues. This phenomenon helps sonographers and physicians differentiate between types of tissues and conditions present within the body, aiding in diagnosis and further management. In contrast, the other options describe characteristics associated with different types of tissues or fluids, which would not exhibit the hyperechoic properties described. For instance, if a mass were less dense or fluid-filled, it would generally appear hypoechoic or anechoic, demonstrating a darker area on the ultrasound. Similarly, inflammation typically leads to changes in tissue echogenicity depending on the presence of edema or other factors, rather than a straightforward hyperechoic appearance.
