Description of normal liver by color Doppler ultrasound: (1) The shape and size of the liver are normal, the ratio of left and right lobes is moderate, the edges are round and blunt, and the surface is neat and smooth.
(2) The liver parenchyma is uniformly and diffusely distributed with tiny light-spot echoes, and the echoes are generally moderate or low.
(3) The intrahepatic duct structures (portal vein, hepatic vein and intrahepatic bile duct) are anechoic areas with normal inner diameter.
When the echo of liver parenchyma thickens and strengthens, suggesting chronic inflammation of liver in chronic liver disease, the echo thickens and strengthens due to the increase of fibrous tissue during the repair process, which is commonly known as "bright liver". Different liver diseases have other special manifestations:
① Chronic viral hepatitis, such as hepatitis B and hepatitis C: only the echo of liver parenchyma is thickened and strengthened.
With the aggravation of liver fibrosis, the echo of liver parenchyma becomes thicker and stronger, and the distribution is uneven.
② Cirrhosis: The volume of the liver is reduced, the edge is blunt, the surface is incomplete, and it is wavy or serrated; The echo of liver parenchyma is thickened and strengthened, unevenly distributed, with nodular feeling, and the pipeline in liver is twisted and deformed.
③ Fatty liver: diffuse enhancement of liver parenchyma echo; However, the liver parenchyma near the skin is enhanced, and the echo of the liver parenchyma far away from the skin is gradually attenuated until it disappears; The liver volume increases; The echo of intrahepatic duct structure is blurred or disappeared.
④ Schistosomiasis liver disease: the echo of liver parenchyma is thickened and strengthened, and the liver is divided into irregular grid-like cells by strengthening fibers, showing cirrhosis.
The analysis of liver color Doppler ultrasound results needs to be comprehensive, and can not be described singly. B-ultrasound examination of patients with hepatitis B big three-yang syndrome found that the echo of liver parenchyma was thickened and enhanced, and two reasons could be confirmed: first, liver fibrosis; Second, there is active hepatitis.
Thickening and enhancement of echo first suggest an increase in liver density. The increase of liver density is nothing more than fibrous tissue left by tissue repair after chronic hepatitis, or active hepatitis, and the blood supply to the liver is enhanced. The former does not necessarily have abnormal liver function, and the latter mostly has elevated liver transaminase, which can be distinguished.
Color Doppler description of normal liver: the size and shape of liver section are normal, the surface is smooth, the spots of liver parenchyma are small and evenly distributed, no obvious occupying lesions are found, the pipeline structure is clearly displayed, the hepatic duct in the liver is not dilated, the inner diameter of portal vein trunk is normal, and no parenchyma filling is found.
Normal liver pays attention to "uniformity and clear structure".
Color Doppler description of liver abnormalities: for example, liver shrinkage, unsmooth surface, thickening and strengthening of light parenchyma points, uneven echo, diffuse lesions, visible space-occupying lesions and so on.
The thickening and enhancement of liver echo may be liver fibrosis caused by hepatitis C or liver parasite infection, and the possibility of cholestatic cirrhosis cannot be ruled out.
Hepatitis B may take more than 65,438+00 years from viral infection to abnormal liver function, to changes in liver density (echo thickening and enhancement), to liver fibrosis, to small nodules, and then to cirrhosis, and may eventually develop into liver cancer.
During this period, patients with hepatitis have many opportunities to control the development of the disease without making it worse.
How does second liver big 3 this world appear liver echo thickening to do? Hepatitis B has a thickening sound of the liver. Considering that fibrosis has occurred, it needs to be dealt with from several aspects:
1, check liver function, whether transaminase and alpha-fetoprotein are elevated. Elevated transaminase requires liver protection treatment. If AFP is elevated, further CT or magnetic resonance is needed to rule out the possibility of liver cancer.
2. Check the DNA quantification of hepatitis B virus. If the virus number is the fifth power of 10, you need to take antiviral drugs; If there is abnormal liver function and the virus number is the fourth power of 10, antiviral treatment should be started.
Don't do anything harmful to the liver. For example, smoking, drinking, taking drugs with liver damage, eating expired and deteriorated food, eating fresh vegetables and fruits as much as possible, and it is best not to eat cooked vegetables overnight.
In short, the course of hepatitis B is about 10-20 years. If it takes a long time, we should pay more attention to reexamination. If you don't review it on time, I'm afraid there will be ascites due to cirrhosis and even liver cancer.
Hello, we know that under normal circumstances, the liver has no light spot and the echo of the liver is uniform. If there is already inflammatory damage to the liver, or there is inflammatory damage to the liver, it will start the process of liver fibrosis, just like a wound on the hand will lead to scarring. If the liver is injured, inflammation can also lead to scars. Then, if these scars are few, it means that the liver spots are dense under B-ultrasound. If they increase and get bigger, they will become thicker. If it is serious, it will be aggravated and even nodules will appear. This time is the performance of cirrhosis. Therefore, the so-called light spot thickening is only the performance of scar tissue in the liver under B-ultrasound. This means that the liver is suffering or has suffered from inflammatory damage. It is necessary to further examine the etiology, actively treat and prevent fibrosis from further developing into cirrhosis.
# The echo of liver parenchyma becomes thicker # # Friends who have been to the hospital know that some diseases can only be detected by B-ultrasound or CT or other more advanced medical equipment, so for some patients with liver diseases, the B-ultrasound list often says that the echo of liver parenchyma becomes bigger or thicker. What is the reason, but I will tell you the reason and the ins and outs.
The first liver disease examination, medically speaking, no matter what kind of liver disease, we should do liver color ultrasound examination. Only through the liver color ultrasound examination, doctors can well understand the shape and size of the patient's liver, the direction of blood vessels in the liver, the degree of damage to liver parenchyma, and whether there are space-occupying lesions. This can be roughly understood from color Doppler ultrasound, so generally speaking, the echo of liver parenchyma is thickened and enhanced, which can also be said to be uniform or uneven distribution, and also reflects the situation of the liver. According to clinical experience, patients with chronic liver disease will appear on B-ultrasound, and the degree of injury represents now, or you have been injured before, which is a sign reflected on color ultrasound. For this description, we still need dynamic observation, combined with blood analysis, or accurate analysis of magnetic resonance CT to prescribe the right medicine, in order to achieve good therapeutic effect.
Second: common diseases of liver parenchyma enhancement. Generally speaking, there must be pathological changes in the liver, which may be caused by inflammation, such as chronic hepatitis, such as hepatitis B, hepatitis C and hepatic hemangioma. Because at this time, mainly because of the decline of liver metabolic function, lipid deposition on liver cell membrane appears, B-ultrasound will prompt enhanced echo, CT will show increased density and accelerated blood flow. It may also cause the echo to increase and thicken, but it does not rule out the manifestations of fatty liver. Other common liver diseases will also appear in the echo enhancement of B-ultrasound, such as hepatitis, cirrhosis, alcoholic hepatitis, liver cancer, etc., which will also promote the echo enhancement. In addition, patients with severe liver diseases will also appear, such as aversion to greasy food, abdominal pain, local pain in the liver, spider nevus and so on. In addition to the physiological indexes of frequent increase of transaminase, increase of bilirubin and decrease of albumin,
Third: Hepatitis B is a big three-yang disease. Generally speaking, hepatitis B is a big three-yang disease, which means that your hepatitis B virus is replicating in a large area, the number of viruses is increasing, and the damage to the human body, especially the liver, is increasing, which is extremely contagious. So according to what you have just described, if you are already a big third world, you should treat it in time and take preventive and health care measures to avoid infecting your family. The following is a comparison of indicators to distinguish big three-yang from small three-yang, and suggestions can be made.
Suggestion: Most common liver diseases are caused by bad living habits. First, make sure you have enough rest time, don't stay up late and don't drink. In addition, it is necessary to ensure a light diet and not to eat greasy and spicy food, because the liver is an organ for detoxification in traditional Chinese medicine, and the above behaviors have increased the operating burden of the liver. In addition, we should pay attention to some hepatitis B virus carriers, such as the ability of viral DNA replication, and so on.
(Special answer: Dr. Zhang, Department of Gastroenterology)
Many patients will have this question. When doing B-ultrasound examination, there will be a description of "thickening and enhancement of liver parenchyma (echo)" on the checklist. So what does this description mean? Do you mean liver disease? Or cirrhosis?
First of all, it should be clear that the B-ultrasound echo of normal liver is composed of tiny light spots with similar size, gray level and uniform distribution. With the progress of chronic liver injury, the echo of intrahepatic B-ultrasound becomes thicker and stronger.
If B-ultrasound finds that the echo of liver parenchyma is thickened and enhanced, it means that liver cells have been damaged. At this time, it is necessary to combine liver function examination and medical history to judge the specific situation of the liver, find out the specific causes of liver injury, and treat the symptoms. Usually, we will first consider whether the patient has a history of hepatitis B, because patients with hepatitis B cirrhosis are often accompanied by enhanced echo of liver parenchyma when doing B-ultrasound examination. Therefore, the thickening of parenchymal echo of liver B-ultrasound does not mean cirrhosis.
If we rule out hepatitis B, we should also consider whether there are obesity, drinking, diet and other factors. In addition, when the liver is ischemic, the echo of liver parenchyma will become thicker and stronger. If only the echo of liver parenchyma is enhanced, it can be recovered through simple nursed back to health and good living habits.
In view of chronic liver injury and early liver cirrhosis, B-ultrasound examination is only an auxiliary examination after all, and the thickening and enhancement of liver parenchyma echo in B-ultrasound examination report only indicates that the liver has inflammation. However, there is no absolutely reliable objective standard for the degree of thickening and strengthening, which is mainly judged by experience and closely related to the performance of the instrument. Therefore, we should look at the results of B-ultrasound objectively.
Therefore, the "thickening and strengthening of liver parenchyma echo" in the B-ultrasound report does not necessarily mean liver cirrhosis. At this stage, it is necessary to actively cooperate with doctors to control the further development of liver disease, because once cirrhosis develops, the difficulty and intensity of treatment will greatly increase.
Thickening and enhancement of liver parenchyma echo is a term used in liver ultrasound examination. Under normal circumstances, the echo of liver color Doppler ultrasound is relatively uniform, showing uniform distribution of tiny light spots, while the tiny blood vessels in the liver run clearly. If the echo of liver parenchyma is thickened and strengthened, it can generally be seen in the following situations:
First, there is inflammation in the liver. When the liver suffers from severe virus attack, such as viral hepatitis, the disease progresses rapidly, and a large number of hepatocytes are destroyed in a short time, which can lead to the thickening and enhancement of the echo of liver parenchyma. In China, hepatitis B, that is, hepatitis B, is more common.
If the echo of liver parenchyma is thickened and enhanced during physical examination, immunological examination should be carried out at the first time to determine whether it is caused by virus infection. Because, when liver cells are destroyed in a short period of time, if not treated in time, it is easy to cause acute liver injury or even a sharp decline in liver function and liver failure, so the consequences are very serious.
Second, patients with long-term anemia will have thickened liver parenchyma echo, which will enhance long-term anemia, especially anemia caused by splenomegaly. Because of hypersplenism, a large number of aging cells are swallowed, and normal cells are constantly swallowed, which is easy to cause anemia with insufficient red blood cells. Because of anemia, the blood supply to the liver is reduced, which will cause portal hypertension for a long time. At this time, a large number of hepatocytes are destroyed, resulting in liver parenchyma damage, and the echo of liver parenchyma will become thicker and stronger.
Third, the impact of drugs on the liver Many drugs are very toxic to the liver, and the metabolism of many drugs mainly depends on the liver. If a large number of drugs are abused for a long time, it may increase the burden on the liver, lead to a large number of liver cells dying and damage the liver parenchyma.
Fourthly, both liver cirrhosis and fatty liver can lead to enhanced echo and thickening of liver parenchyma. Liver cirrhosis and fatty liver are the consequences of fatty degeneration of liver cells. Early mild fatty liver can enhance the echo spots of liver parenchyma and slightly thicken them. However, with the development of fatty liver, there is more and more fat in the cracks of liver cells, and more and more liver cells are squeezed, deformed and necrotic. Fatty degeneration of hepatocytes is becoming more and more serious, which will lead to a large number of hepatocyte deaths and damage the liver parenchyma.
In fact, we can not only rely on B-ultrasound to judge the health of the liver, but also rely on specific clinical manifestations. If a person with a history of hepatitis B, if the echo of liver parenchyma becomes thicker and stronger, it is likely that the liver is seriously damaged and needs timely treatment. At this time, in addition to liver function and B-ultrasound, patients also need to do hbv-dna test and virus mutation drug resistance test to understand the virus replication and virus number in patients, and then choose appropriate antiviral drugs for treatment according to the test results.
At the same time of treatment, comprehensive anti-HBV treatment can be carried out with drugs, which can greatly shorten the time of three positive to negative and reduce the side effects of single drug use. In addition, avoid eating a lot of foods with high salt content in daily life, because nitrite is a common carcinogen that causes liver cancer. Don't stay up late, it will destroy the normal biological clock of the liver and affect its normal metabolism and self-repair function.
The questions raised by the subject should also be the questions that most ordinary people without medical professional knowledge want to know. To understand this problem, we must first know what liver essence is and what echo is. As for boldness, it is relatively easy to understand, and boldness is thicker and stronger than the reference.
Let's talk about liver parenchyma and echo in detail first. Liver parenchyma is a part of the liver, which consists of liver parenchyma and liver interstitial. Liver parenchyma is the most important part of the liver. In fact, hepatocytes constitute the essence of the liver. The part that connects and supports liver cells is called liver stroma, just like a bunch of grapes. If a grape is equivalent to the cells of the liver, then the stem connecting the grapes is interstitial, so that we can better understand it.
Then if the liver parenchyma is diseased, it is just like the grapes are wrinkled or broken. It is a truth that the original round, full and delicate feeling becomes wrinkled and rough.
For the liver, inflammation is the most important and common cause. Of course, the cause of inflammation can be virus or bacteria, and it can also be drugs or alcohol, such as hepatitis A, hepatitis B and hepatitis C. Some drugs cause damage to the liver, which is called drug hepatitis, and hepatitis caused by drunkenness and alcoholism is called alcoholic hepatitis, but it will eventually cause damage to liver cells and make the appearance of liver cells undergo destructive changes.
But this change is invisible to the naked eye, because we are separated by structures such as abdomen and subcutaneous fat, so we have to rely on human wisdom and modern science to develop and manufacture medical instruments, such as color Doppler ultrasound, CT and nuclear magnetic resonance.
Echo is the principle of using ultrasound to check your body, which means that when you encounter obstacles, you are forced to return. Sound is sound waves, which are divided into ultrasonic waves, sound waves and infrasound waves according to frequency and wavelength, but the only part that our human body can receive through our ears is sound waves, and the ultrasonic instrument uses ultrasonic waves. Therefore, when we examine our body with ultrasonic waves, we need the probe to emit ultrasonic waves, and the ultrasonic waves are reflected by the examined body organs and detected by the ultrasonic probe, so the detected echo is called "echo", and the echo is processed to get the image anatomy that we can see with the naked eye. This is the same as bats that prey on sound waves in nature.
Looking back, because the density of organs and tissues in the body is different and the sensitive wavelength is different, the ultrasonic probes for the heart, neck, epigastrium, liver, gallbladder, spleen, pancreas, kidney and blood vessels are also different, because the ultrasonic wavelength emitted by each probe is different.
Through the above introduction, I believe you can understand the thickening and enhancement of liver parenchyma echo, and the result of liver parenchyma injury is the thickening and enhancement of liver parenchyma echo. Then there are many reasons for liver parenchymal damage. All kinds of hepatitis, drug damage to the liver, alcohol damage to the liver and fatty liver can all be manifested as enhanced echo of liver parenchyma.
Hello, under normal circumstances, the echo inside the liver of a healthy person is composed of tiny light spots with similar size and gray level, which are evenly distributed. However, the thickening and enhancement of liver tissue echo is generally caused by liver cell damage. Moreover, with the progress of chronic liver injury, the echo in the liver becomes thicker and stronger, which may be due to the invasion of hepatitis B virus into the liver, resulting in liver cell damage and fibrous connective tissue proliferation, which is manifested as enhanced echo in the liver.
If the virus is not controlled, the sustained damage of the liver may further develop into liver fibrosis and cirrhosis. When there is obvious connective tissue hyperplasia, diffuse linear echoes and sometimes nodular echoes can be seen in the liver parenchyma. The echo of liver parenchyma changes more obviously in cirrhosis, showing thicker and stronger echo, and patchy strong echo areas can be seen. We can judge the degree of liver injury, whether it has reached cirrhosis and whether there is venous hypertension, and help distinguish gastrointestinal bleeding through the different intensity of liver echo.
Thickening of liver echo can appear in all liver injuries caused by it. Such as virus infection and drug damage. Autoimmune damage, fatty liver, alcohol, etc.
Hello, I'm a professional and humorous Tian Luo pharmacist, and I'm glad to answer your question. You are asking: "What do you mean by thickening and enhancing the echo of liver parenchyma?" This question is explained by Tian L Luo Pharmacist as follows.
Please listen to the specific explanation of pharmacist Tian Luo.
The thick and enhanced echo of liver parenchyma is caused by many diseases of the liver, such as fatty liver and drug-induced liver injury.
If there are symptoms such as abnormal liver function, pain and swelling in the liver area, yellow eyes, yellow hands and yellow body, you should go to the hospital in time; If there are no clinical symptoms, regular follow-up is enough.
In life, pay attention to exercise more, avoid obesity, eat less greasy food, live a regular life and avoid drinking and staying up late. Is that what I mean by "thickening and enhancing the echo of liver parenchyma"? I hope I can help you.
I'm Dr. Luo from Tiancheng Kangkang, your family health housekeeper, and I'm willing to share more interesting, high-quality and rigorous health information with you to solve family health problems. Kangkang will work with you hand in hand! Pay attention to @ Tiancheng Kangkang L Luo Pharmacist and share more healthy dry goods. The description of your liver by B-ultrasound can be divided into several stages: the light spot of liver parenchyma is slightly thicker ~ the light spot of liver parenchyma is thicker ~ chronic inflammatory changes of liver ~ diffuse inflammatory changes of liver ~ cirrhosis.
Generally speaking, there is no big problem if the light spot is a little thicker or thicker, indicating that the morphological changes of the liver are not obvious. If you are not at ease, you can do a liver hardness test to see the degree of liver fibrosis.
