Ultrasonography of the liver and gall bladder in cattle

One of the methods, used today to detect liver parenchyma lesions, liver vessels, bile ducts and gallbladder is ultrasonography. Therefore, this technique is method of choice for diagnosing some of the liver diseases in humans and animals. It is necessary to mention that, any changes in liver tissue, make changes in echogenicity and homogenous appearance of the liver in ultrasonography. Hence, the detection of Space-occupying lesions such as cysts, abscesses tumors, as well as calcified areas are better to detect with ultrasonography, than diffuse lesions, such as hepatitis, fatty liver and hepatic cirrhosis. Ultrasonography in ruminants is the only diagnostic imaging technique which can be used for evaluation of liver in ruminant. It should be mentioned, that in ruminant, most liver diseases are detected only in post-mortem examinations, while, ultrasonography can also be used to diagnose some of liver diseases in clinic.
