Hypoechoic and Hyperechoic To better understand isoechoic, it’s important to distinguish it from two related A hyperechoic structure appears brighter on the screen because it strongly reflects ultrasound waves. Examples include bone and fat calcifications. Hypoechoic. For instance, dense tissues, like bone, appear very bright (hyperechoic), while fluid-filled structures appear dark (anechoic) because they transmit sound waves readily. 5% in solid Tissues that reflect a significant amount of sound waves are called hyperechoic, or echogenic, and appear bright white on the ultrasound image. Nyberg DA, Dubinsky T, Resta RG, Hyperechoic liver lesions can be detected on US due to the increased reflection of US waves caused by factors including fatty deposits, sinusoidal dilation, peliotic changes, Another example of hyperechoic kidney obtained from a patient with CKD stage IV.
