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.
Hepatomegaly is enlargement of the liver. The liver edge is normally palpable in children and thin adults and some patients may have a palpable right lobe of the liver. It is smooth, uniform, non-tender and descends to meet the palpating fingers on inspiration. The best way to assess size is by percussion - a normal-sized liver can appear enlarged if displaced downwards by lung disorders. An enlarged liver expands down and across towards the left iliac fossa (LIF). To avoid missing a really big liver, always begin liver palpation in the LIF and work towards the right upper quadrant. The most common causes of hepatomegaly in the UK are alcoholic liver disease, malignancy (particularly metastases) and congestive cardiac failure.
