The standard representation is brighter color for higher echogenicity, giving the almost anechoic fluid an almost black appearance. Echogenicity (misspelled sometimes as echogenecity) 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.
