It is unique or paucilocular. It can be associated with other types of benign liver tumors. Characteristic 2D ultrasound appearance is that of a very well defined lesion, with sizes of 2–3 cm or less, showing increased echogenity and, when located in contact with the diaphragm, a "mirror image" phenomenon can be seen.
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
Gallbladder cancer is a relatively uncommon cancer, with an incidence of fewer than 2 cases per 100,000 people per year in the United States. [7] It is particularly common in central and South America, central and eastern Europe, Japan and northern India; it is also common in certain ethnic groups e.g. Native American Indians and Hispanics.

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.
Ultrasound of the liver and biliary tree is often used as the initial imaging modality in people with suspected obstructive jaundice. [49] [50] Ultrasound can identify obstruction and ductal dilatation and, in some cases, may be sufficient to diagnose cholangiocarcinoma. [51]
Cancers of the gallbladder are typically adenocarcinomas, and are common in elderly women. Gallbladder cancer is strongly associated with gallstones, a porcelain gallbladder appearance on ultrasound, and the presence of polyps within the gallbladder. Gallbladder cancer may manifest with weight loss, jaundice, and pain in the upper right of.
Gallbladder diseases are diseases involving the gallbladder and is closely linked to biliary disease, with the most common cause being gallstones (cholelithiasis). [1] [2]The gallbladder is designed to aid in the digestion of fats by concentrating and storing the bile made in the liver and transferring it through the biliary tract to the digestive system through bile ducts that connect the ...
Ultrasound image showing the liver, gallbladder and common bile duct. 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. Uses of ultrasound are much broader, however.
