Diffuse liver changes: more research is needed
- Diffuse liver changes: more research is needed
Ultrasound diagnostics - one of the main methods of examination used in various diseases of the liver.But a diagnosis based on ultrasound alone is not possible, it requires more additional methods, such as laboratory and instrumental studies.
little about the structure and functions of the liver
liver is unpaired parenchymal organ (which means that it consists entirely of liver tissue and has no cavity), located in the abdomen in the right hypochondrium.The basis of the liver parenchyma up segments, between which the blood vessels and bile ducts.Bile ducts tolerate bile in the gall bladder, where it is on the common bile duct enters the duodenum, connecting with pre-pancreatic duct (which is why any disease of the liver and biliary tract always reflected the state of the pancreas and vice versa).
liver performs different and very important for the body's functions.
First of all, it decomposed into harmless metabolites toxic substances, which appear in the blood as a result of metabolism.In addition, it needed to synthesize proteins and is deposited body glycogen (glucose reserves Glucose: power source "rainy day") are degraded proteins, which are then excreted.Finally, in liver bile is formed, which is impossible without digestion.
ultrasonography (US) is based on the principle of echolocation - the reflection of the ultrasonic tissue rather the interface tissue fluids having different abilities to reflect ultrasound.Since doctors of ultrasound diagnostics are well aware how certain tissue reflect the ultrasound is normal, they see and pathological changes in the tissues.When liver ultrasound is one of the main methods.When detected by ultrasound in the tissues of some changes (to the US often fail to clarify what it is) for diagnosis is carried out a number of additional tools and laboratory tests.
mainly on ultrasound revealed a variety of focal changes in the liver.It may be a tumor, cyst, stones.But there are diffuse, ie widespread changes in the liver.
What is diffuse changes in the liver
The normal liver tissue is represented slaboehogennoy homogeneous structure, among which you can see blood vessels and bile ducts with higher echogenicity.Diffuse changes in liver parenchyma say that changed the whole liver tissue.This can be as little functional change, and its heavy defeat.Therefore, to clarify the diagnosis carried out additional studies.First of all, this laboratory studies that reveal how hurt liver function.In addition, studies are biliary tract, duodenum, pancreas Diabetes and pancreas - the things you need to know if necessary - the state of the digestive organs.
conclusion of US "Diffuse changes in the liver," can be with viral hepatitis, alcoholic hepatitis, fatty liver, and various other metabolic liver diseases.
So, for example, fatty degeneration of the liver tissue (this may be the result of many diseases - chronic alcoholism, diabetes, obesity), it increased in size, its structure increased echogenicity compared to the norm.The slight increase in liver with increased echogenicity of the tissue it may be in chronic hepatitis Chronic hepatitis - a diagnosis for life (it can also occur due to various reasons - in viral lesions, with chronic alcoholism).In order to find out what caused these diffuse changes in the liver, it is necessary to conduct a number of additional studies.
In acute hepatitis Acute hepatitis - always serious any origin liver is enlarged and the tissue it is often a heterogeneous structure in the US due to areas with varying degrees of echogenicity.Here you can see the enlarged lymph nodes in the liver.This picture also needs clarification with additional research methods.
more specific kind of liver on ultrasound when it is cirrhosis (degeneration of liver tissue in the connective tissue with reduced liver function).At the same time the contours of the liver become uneven, bumpy (with small and large mounds).Liver tissue echogenicity is unequal due to proliferation of connective tissue, which has a higher echogenicity as compared to liver tissue.According to some additional features can assume the nature of cirrhosis.Thus, in alcoholic liver cirrhosis gradually reduced in size - generally decreases the right lobe of the liver, while the left lobe may even increase slightly (compensatory reaction).Other cirrhosis also have their own distinctive features.Even the diagnosis of cirrhosis of the liver, which has a fairly characteristic features on the ultrasound, can not be made solely on the basis of this study.
Thus, the conclusion of US "Diffuse changes in the liver" in itself means only that the liver has some changes, which it must show more research.
