Hepatic fatty infiltration sonographically appears as an area of increased echogenicity. When focal areas of fat are present in otherwise normal liver parenchyma, the fatty area may be masslike in appearance, leading to further imaging e... SF Quinn,BB Gosink - 《Ajr American Journal of Roentge...
. Therefore we objectively evaluated low echogenicity on ultrasonography of thyroid using WinROOF ver. 7.0. image analysis software. Thyroid lymphomas, especially DLBCLs are characteristic of medullary tumors composed of condensed tumor cells[20]that might be associated with increased low echogenicity....
22,23,24. Heterogeneous echogenicity is caused by multiple structures of different acoustic impedances creating variable echogenicity degrees on US, and the normal representative tissue is muscle25. When healthy, organs such as the thyroid gland or liver consist of characteristic cells with little vari...

Infiltration within the liver occurs predominantly along the sinusoids and results in the non-specific signs of hepatomegaly, increased echogenicity at US with hypoattenuation at CT mimicking steatosis and heterogeneous enhancement following contrast medium administration. Elastography demonstrates increased ...
