The echo texture of an organ is its ability to bounce an echo (of an ultrasound, for example) off the surface. The parenchymal structure of the liver is its connective tissue. If the echo texture is increased, that means the density of the liver has increased.

Macro anatomy of liverFor the ease of understanding , liver is anatomically divided into lobes. On its top view, liver shows the left and right lobes separated by the falciform ligament. On the inferior view (from below), it appears with four lobes. However, the organ is roughly divided into 2 principal lobes, right and a left lobe. The falciform ligament forms a septum resulting in the left and right lobes. The abdomen and the liver is thinly separated by a membrane called peritoneum. Peritoneum is the covering layer of all the abdominal organs. Peritoneum has 2 divisions; outer parietal divisions and the inner visceral layer that actually touches the surface of liver. Liver is surrounded by a number of organs forming various impressions. Some of the impressions are gastric impression, renal impression, suprarenal impression, colic impression, and duodenal impression.Microscopic anatomy of liverUnlike other organs, the liver is supplied with two major sources of blood; the portal channel and the hepatic channel. The hepatic artery connected to the major abdominal aorta brings pure blood from the heart, similarly, the impure blood is removed from the liver with the help of 3 hepatic veins. Additionally, portal circulation rich in multiple capillaries and veins also supply the blood from in and out of the liver. Microscopically, liver is divided into a number of hepatic lobules. Each lobule appears hexagonal made up of plates of hepatocytes. Hepatocytes (liver cells) joins the central vein that carry blood out of the liver. If we analyse the histology (microscopic anatomy) of the liver, two major types of liver cells are found: parenchymal cells and the non-parenchymal cells. 3/4th of the liver is filled with the parenchymal hepatocytes and the remaining ¼ is made up of non-parenchymal cells. The liver contains sinusoids, lined with 2 types of cells called sinusoidal endothelial cells, and phagocytic Kupffer cells. Furthermore, hepatic stellate cells are one of the type of non-parenchymal cells found alongside perisinusoidal space, between a sinusoid and a hepatocyte, some intrahepatic lymphocytes are often found within the sinusoidal lumen. The functional lobes of the liver are separated by the imaginary plane called Cantlie's line that joins the gallbladder fossa to the inferior vena cava. The plane separates the liver into left and the right lobes. The middle hepatic vein also demarcates the true right and left lobes.
What is chronic parenchymal volume loss?
Chronic parenchymal volume loss is long-standing decrease in the amount of space taken up by the bulk of the organ.
Tomato pulp is composed of what type of cells?
Parenchymal cells.
What is the meaning of slightly altered parenchymal epitexture in ct scan?
It is not a "parenchymal epitexture" it is a "parenchymal echotexture" and it is indicating damage to the liver.
Diffusely increased in echotexture of the liver?
Diffusely increased echotexture in the liver is typical of a fatty liver. When a liver is fatty it takes on a spongy appearance. This can be caused by either alcoholic or non alcoholic reasons.
What is minimal coarsening hepatic echotexture?
i just saw my abdominal echo and the results showed mild coarsening of the hepatic echotexture that could be related to diffuse hepatocelluiar disease. what does this mean> can it be cancer of liver?
Whether there is possibility of carcinoma from parenchymal liver disease?
Risk is increased if there is cirrhosis, for example alcoholic or viral hepatitis related.
What is renal parenchymal echogenicity?
Parenchyma is the functional part of an organ (while stroma is the supporting tissue). Echogenicity means ability to produce an echo. So parenchymal echogenicity means the ability of the functional part of an organ to produce an echo (for ultrasound examination for example).
Is the liver the largest parenchymal organ in the abdominal cavity?
The liver is the biggest organ in the abdominal cavity.
What is the homogeneous echo-texture in prostate gland?
i had test done an it said the liver appears homogeneous in echotexture with no evidence of hepatic mass or perihepatic collecttion ... so i am needing to know what that means do i have cancer in my liver ?
What is the tissues of the liver and their function?
Liver tissue is made up of two types of cells: karat parenchymal and non-parenchymal cells. The karat parenchymal cells are known as hepatocytes. There are several types of non-parenchymal cells: Sinusoidal hepatic endothelial cells, Kupffer cells and hepatic stellate cells. The liver has a number of functions, including synthesizing hormones and breaking down substances for metabolization by the body's various systems.
What is a liver filled with homogenous parenchymal echoes?
A liver filled with homogeneous parenchymal echos is one that shows no signs of disease or cirrhosis of the liver. If the liver was filled with inhomogeneous parenchymal echoes, that would show signs of disease or cirrhosis of the liver.This can indicate a number of liver disease types, such as cirrhosis, metastatic disease, fatty liver, chronic hepatitis, and lymph proliferative disease. Further investigation is needed for a definitive diagnosis.
What is homogenous in echotexture?
what is normal in size but shows bright homogeneous echotexture in liver
What does increased echo texture of the liver mean?
An increased echotexture of the liver could mean several different things. A doctor is the only one who can diagnose what it means in a certain case. It would be caused by cirrhosis, or hepatitis, or fatty infiltration just to name a few things it could mean.
What is hepatic parenchymal calcifications?
Areas of calcium inside the "meat" of the liver (not in the different local vessels).
