Report Abuse. Routers and modems are two of the most common computer peripherals, yet many people don't know the function of each one. While the two devices may look similar, they each serve a difference purpose. Fortunately, the functions of the two devices are pretty easy to understand.
I read your question. Echogenicity is the ability to create an echo, i.e. return a signal in ultrasound examinations. Increased echogenicity of the liver usually means that there is fatty infiltration in parts of the liver. In certain causes a focal area of increased echogenicity would indicate a discrete mass.
Answer   Parenchyma is the functional part of an organ (while stroma is the supporting tissue). Echogenicity means ability to produce an echo. So parenchymal echogenicity â¦ means the ability of the functional part of an organ to produce an echo (for ultrasound examination for example).arenchymal liver disease is any disease of the functional cells of the liver, as opposed to the bile duct cells or supporting cells.
