Ultrasonography of liver tumors involves two stages: detection and characterization. [ 1 ] Tumor detection is based on the performance of the method and should include morphometric information (three axes dimensions, volume) and topographic information (number, location specifying liver segment and lobe/lobes).
Abdominal ultrasonography of the liver, as a sagittal plane through the midclavicular line, with some standard measurements [2] Right lobe of the liver at the midclavicular line at ages 0 to 7 [16] Suspicion of hepatomegaly indicates a thorough medical history and physical examination , wherein the latter typically includes an increased liver ...
The word "cirrhosis" is a neologism derived from Greek: κίρρωσις; kirrhos κιρρός, meaning "yellowish, tawny" (the orange yellow colour of the diseased liver) and the suffix -osis, i.e. "condition" in medical terminology. [160] [161] [162] While the clinical entity was known before, René Laennec gave it this name in an 1819 paper ...
Fatty liver could cause increased echogenicity in the liver, especially if the liver transaminases are elevated. [3] Women with polycystic ovary syndrome may also show an increase in stromal echogenicity.
Fatty liver disease (FLD), also known as hepatic steatosis and steatotic liver disease (SLD), is a condition where excess fat builds up in the liver. [1] Often there are no or few symptoms. [ 1 ] [ 2 ] Occasionally there may be tiredness or pain in the upper right side of the abdomen . [ 1 ]
Chronic liver disease takes several years to develop and the condition may not be recognised unless there is clinical awareness of subtle signs and investigation of abnormal liver function tests. Testing for chronic liver disease involves blood tests, imaging including ultrasound, and a biopsy of the liver. The liver biopsy is a simple ...
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.
The liver parenchyma is the functional tissue of the organ made up of around 80% of the liver volume as hepatocytes. The other main type of liver cells are non-parenchymal. Non-parenchymal cells constitute 40% of the total number of liver cells but only 6.5% of its volume. [11]
