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.
Cardiac echogenic foci (ICEF) are abnormalities in the heart of a fetus. First detected by ultrasound in 1987, these foci appear as bright, white spots. The exact cause of these foci remains unclear; however, they appear, at least in part, to be the result of calcium deposits forming in the heart muscle. ICEF are not heart defects, nor do they appear, in the majority of cases, to affect cardiac function or lead to heart disease.
