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.
Transverse image of the liver shows a heterogeneous echotexture with diffusely increased echogenicity. This patient proved to have diffuse metastatic renal cell carcinoma. Most metastatic deposits are solid and mainly hypoechoic relative to the background liver (Fig. 4). Many will exhibit a hypoechoic halo (Fig.y ultrasound metastases to the liver usually take on one of the following appearances: (1) hypoechoic mass, (2) mixed echogenicity mass, (3) mass with target appearance, (4) uniformly echogenic mass, (5) cystic mass, or (6) heterogeneous or coarse echo texture without focal mass (Fig.
