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.
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).
Parenchymal calcification refers to the abnormal accumulation of calcium deposits within the parenchymal tissues of an organ. This calcification can occur due to various conditions such as infections, inflammation, or metabolic disorders and may affect the normal function of the organ. Detection of parenchymal calcifications on imaging studies like X-rays or CT scans can help in diagnosing underlying diseases.
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.
An echogenic liver refers to a liver with increased density on ultrasound imaging, which can indicate various conditions such as fatty liver disease, cirrhosis, or liver inflammation. Further evaluation by a healthcare provider is usually needed to determine the underlying cause and appropriate treatment.
Cocaine is not directly toxic to the liver, but chronic cocaine use can lead to health issues that may affect liver function indirectly. These can include reduced blood flow to the liver, increased risk of hepatitis infections, and a higher likelihood of engaging in risky behaviors that can harm the liver.
It is not a "parenchymal epitexture" it is a "parenchymal echotexture" and it is indicating damage to 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.
Homogeneous parenchymal echotexture refers to an ultrasound finding where the tissue being examined (such as the liver or kidney) appears uniform in texture throughout, without any areas of abnormality or variation in echogenicity. This can suggest normal tissue architecture and lack of pathology in the organ.
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?
Risk is increased if there is cirrhosis, for example alcoholic or viral hepatitis related.
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).
The liver is the biggest organ in the abdominal cavity.
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 ?
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.
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.
Hepatomegaly with a heterogeneous echotexture means that the liver is enlarged and appears to have a varied and irregular texture on ultrasound imaging. This can be caused by various conditions such as cirrhosis, fatty liver disease, or liver inflammation. Further evaluation, including blood tests and possibly a liver biopsy, may be needed to determine the underlying cause.
Diffusely coarsened echotexture refers to a change in the ultrasound appearance of tissues, typically indicating a pathological process. This term is often used to describe liver conditions, where the normal, fine echotexture becomes more heterogeneous and coarse due to factors like fatty infiltration, fibrosis, or cirrhosis. The altered echogenicity and texture can be indicative of underlying liver disease or other organ pathologies.
