Echogenicity or echogeneity is the ability to bounce an echo, e.g. return the signal in ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves. Tissues that have higher echogenicity are called hyperechogenic and are usually represented with lighter colors on images in medical ultrasonography. In contrast, tissues with lower echogenicity are called hypoechogenic and are usually represented with darker colors. Are
