In some cases this accumulation can mimic a liver tumor. Sometimes the opposite phenomenon can be seen, that is an "island" of normal parenchyma in a “shining” liver. In both cases ultrasound examination identifies a well defined, un-encapsulated area, with echostructure and vasculature similar to those of normal liver parenchyma.
Mumoli's sign (also known as a "Playboy Rabbit" sign) is a radiologic sign seen in the normal liver. It appears as a rabbit-shaped image caused by the confluence of the middle and right hepatic veins as they merge with the inferior vena cava. It can be seen on ultrasound images of the liver with a transverse subcostal view during deep inspiration.
Medical ultrasound uses high frequency broadband sound waves in the megahertz range that are reflected by tissue to varying degrees to produce (up to 3D) images. This is commonly associated with imaging the fetus in pregnant women.
NAFLD is often diagnosed through medical history, blood tests, physical exams and imaging tests, like ultrasound or MRI. These methods can help reveal fatty deposits in the liver and rule out ...
A cavernous liver hemangioma or hepatic hemangioma is a benign tumor of the liver composed of large vascular spaces lined by monolayer hepatic endothelial cells. It is the most common benign liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging or during laparotomy for other intra-abdominal issues.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
A complete blood test can help distinguish intrinsic liver disease from extrahepatic bile-duct obstruction. [19] An ultrasound of the liver can reliably detect a dilated biliary-duct system, [20] it can also detect the characteristics of a cirrhotic liver. [21] Computerized tomography (CT) can give accurate anatomical information for a complete ...
In steatosis, there is a difference between the density and brightness of the two organs, with the liver appearing darker. [12] On ultrasound, fat is more echogenic (capable of reflecting sound waves). The combination of liver steatosis being dark on CT and bright on ultrasound is sometimes known as the flip flop sign.
