Echogenicity (sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in medical ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves.
Hypoechoic – less echogenic (darker) than normal; Isoechoic – the same echogenicity as another tissue; Transvaginal ultrasonography – Ultrasound is performed through the vagina; Transabdominal ultrasonography – Ultrasound is performed across the abdominal wall or through the abdominal cavity
Renal ultrasonography (Renal US) is the examination of one or both kidneys using medical ultrasound. Ultrasonography of the kidneys is essential in the diagnosis and management of kidney-related diseases.

During the portal venous phase there is a specific "wash out" of ultrasound contrast agent (UCA) and the tumor appears hypoechoic during the late phase. Poorly differentiated tumors may have a stronger wash out leading to an isoechoic appearance to the liver parenchyma during portal venous phase.
