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.
An 86-year old man had a non-contrast thoracic CT for evaluation of a chest x-ray abnormality. Incidentally, the CT scan showed diffuse increase in liver density with Hounsfield units of 105. The normal unenhanced attenuation value is between 55-65 Hounsfield units in a normal liver on CT scan without contrast (1). Hepatic attenuation is reflected in Hounsfield values and depends on combinations of factors including the presence or absence (as well as phase) of IV contrast administration.
