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).
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
Like most liver tumors, the anatomy and location of the adenoma determines whether the tumor can removed laparoscopically or if it requires an open surgical procedure. [7] Hepatocellular adenomas are also known to decrease in size when there is decreased estrogen or steroids (e.g. when estrogen-containing contraceptives, steroids are stopped ...
A liver sinusoid is a type of capillary known as a sinusoidal capillary, discontinuous capillary or sinusoid, that is similar to a fenestrated capillary, having discontinuous endothelium that serves as a location for mixing of the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein.
Axial and coronal images in the portal venous phase. Increased pressure in the sublobular branches of the hepatic veins causes an engorgement of venous blood, and is most frequently due to chronic cardiac lesions , especially those affecting the right heart (e.g., right-sided heart failure ), the blood being dammed back in the inferior vena ...
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue , consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein .
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 ...
Although the LSECs make up only about 3% of the total liver cell volume, their surface in a normal adult human liver is about 210 m 2, or nearly the size of a tennis court. [1] The LSEC structure differs from other endothelia. The cells contain many open pores, or fenestrae, with diameters from 100 to 150 nm.
