Liver Imaging: From 1 Different Sources
Techniques that produce images of the liver, gallbladder, bile ducts, and blood vessels supplying the liver, to aid the detection of disease.
Ultrasound scanning, CT scanning, and MRI are commonly used.
Radionuclide scanning may reveal cysts and tumours and show bile excretion.
X–ray techniques include cholangiography, cholecystography, and ERCP (endoscopic retrograde cholangiopancreatography).
In these procedures, a contrast medium, which is opaque to X-rays, is introduced to show abnormalities in the biliary system.
Angiography reveals the blood vessels in the liver.
The liver is the largest gland in the body, serving numerous functions, chie?y involving various aspects of METABOLISM.
Form The liver is divided into four lobes, the greatest part being the right lobe, with a small left lobe, while the quadrate and caudate lobes are two small divisions on the back and undersurface. Around the middle of the undersurface, towards the back, a transverse ?ssure (the porta hepatis) is placed, by which the hepatic artery and portal vein carry blood into the liver, and the right and left hepatic ducts emerge, carrying o? the BILE formed in the liver to the GALL-BLADDER attached under the right lobe, where it is stored.
Position Occupying the right-hand upper part of the abdominal cavity, the liver is separated from the right lung by the DIAPHRAGM and the pleural membrane (see PLEURA). It rests on various abdominal organs, chie?y the right of the two KIDNEYS, the suprarenal gland (see ADRENAL GLANDS), the large INTESTINE, the DUODENUM and the STOMACH.
Vessels The blood supply di?ers from that of the rest of the body, in that the blood collected from the stomach and bowels into the PORTAL VEIN does not pass directly to the heart, but is ?rst distributed to the liver, where it breaks up into capillary vessels. As a result, some harmful substances are ?ltered from the bloodstream and destroyed, while various constituents of the food are stored in the liver for use in the body’s metabolic processes. The liver also receives the large hepatic artery from the coeliac axis. After circulating through capillaries, the blood from both sources is collected into the hepatic veins, which pass directly from the back surface of the liver into the inferior vena cava.
Minute structure The liver is enveloped in a capsule of ?brous tissue – Glisson’s capsule – from which strands run along the vessels and penetrate deep into the organ, binding it together. Subdivisions of the hepatic artery, portal vein, and bile duct lie alongside each other, ?nally forming the interlobular vessels,
which lie between the lobules of which the whole gland is built up. Each is about the size of a pin’s head and forms a complete secreting unit; the liver is built up of hundreds of thousands of such lobules. These contain small vessels, capillaries, or sinusoids, lined with stellate KUPFFER CELLS, which run into the centre of the lobule, where they empty into a small central vein. These lobular veins ultimately empty into the hepatic veins. Between these capillaries lie rows of large liver cells in which metabolic activity occurs. Fine bile capillaries collect the bile from the cells and discharge it into the bile ducts lying along the margins of the lobules. Liver cells are among the largest in the body, each containing one or two large round nuclei. The cells frequently contain droplets of fat or granules of GLYCOGEN – that is, animal starch.
Functions The liver is, in e?ect, a large chemical factory and the heat this produces contributes to the general warming of the body. The liver secretes bile, the chief constituents of which are the bile salts (sodium glycocholate and taurocholate), the bile pigments (BILIRUBIN and biliverdin), CHOLESTEROL, and LECITHIN. These bile salts are collected and formed in the liver and are eventually converted into the bile acids. The bile pigments are the iron-free and globin-free remnant of HAEMOGLOBIN, formed in the Kup?er cells of the liver. (They can also be formed in the spleen, lymph glands, bone marrow and connective tissues.) Bile therefore serves several purposes: it excretes pigment, the breakdown products of old red blood cells; the bile salts increase fat absorption and activate pancreatic lipase, thus aiding the digestion of fat; and bile is also necessary for the absorption of vitamins D and E.
The other important functions of the liver are as follows:
In the EMBRYO it forms red blood cells, while the adult liver stores vitamin B12, necessary for the proper functioning of the bone marrow in the manufacture of red cells.
It manufactures FIBRINOGEN, ALBUMINS and GLOBULIN from the blood.
It stores IRON and copper, necessary for the manufacture of red cells.
It produces HEPARIN, and – with the aid of vitamin K – PROTHROMBIN.
Its Kup?er cells form an important part of the RETICULO-ENDOTHELIAL SYSTEM, which breaks down red cells and probably manufactures ANTIBODIES.
Noxious products made in the intestine and absorbed into the blood are detoxicated in the liver.
It stores carbohydrate in the form of glycogen, maintaining a two-way process: glucose
glycogen.
CAROTENE, a plant pigment, is converted to vitamin A, and B vitamins are stored.
It splits up AMINO ACIDS and manufactures UREA and uric acids.
It plays an essential role in the storage and metabolism of FAT.... liver
Cod-liver oil is derived from the fresh liver of the cod (Gadus callarius). It is a rich source of vitamin D, used in the prevention and treatment of RICKETS, and of vitamin A. Human milk contains more than enough vitamin D for the breast-fed baby, provided the mother has a balanced diet with adequate exposure to sunlight, or is taking vitamin supplements during pregnancy and lactation if considered necessary. All baby foods in the UK contain added vitamins, and therefore supplementation is unnecessary until weaning begins, and the baby starts taking cow’s milk, which contains less vitamin D than human milk.

Paul Bergner describes 4 cases of patients with chronic hepatitis C successfully treated. All were given Milk Thistle, and prescribed an alternative tea: equal parts, Burdock, Dandelion, Barberry, Liquorice, Cinnamon and Fennel. Chologogue action is important in chronic liver disease. Not used in acute inflammation. All patients felt better within 2 weeks, and had liver function tests at 3-monthly intervals, showing a gradual decline in elevated values until normal or almost so. All patients became symptom-free. (Medical Herbalism, Vol 6, No 4) ... liver – hepatitis c

The LIVER may be extensively diseased without any obviously serious symptoms, unless the circulation through it is impeded, the out?ow of BILE checked, or neighbouring organs implicated. JAUNDICE is a symptom of several liver disorders, and is discussed under its separate heading. ASCITES, which may be caused by interference with the circulation through the portal vein of the liver, as well as by other reasons, is also considered separately. The presence of gallstones is a complication of some diseases connected with the liver, and is treated under GALLBLADDER, DISEASES OF. For hydatid cyst of the liver, see TAENIASIS. Liver diseases in a tropical environment are dealt with later in this section.
In?ammation of the liver, or HEPATITIS, may occur as part of a generalised infection or may be a localised condition. Infectious hepatitis, which is the result of infection with a virus, is one of the most common forms. Many di?erent viruses can cause hepatitis, including that responsible for glandular fever (see MONONUCLEOSIS). Certain spirochaetes may also be the cause, particularly that responsible for LEPTOSPIROSIS, as can many drugs. Hepatitis may also occur if there is obstruction of the BILE DUCT, as by a gall-stone.
Cirrhosis of the liver A disorder caused by chronic damage to liver cells. The liver develops areas of ?brosis or scarring; in response, the remaining normal liver cells increase and form regeneration nodules. Those islands of normality, however, suffer from inadequate blood supply, thus adversely affecting liver function. Alcohol is the most common cause of cirrhosis in the United Kingdom and the USA, and the incidence of the disorder among women in the UK has recently risen sharply as a consequence of greater consumption of alcohol by young women in the latter decades of the 20th century. In Africa and many parts of Asia, infection with hepatitis B virus is a common cause. Certain drugs – for example, PARACETAMOL – may damage the liver if taken in excess. Unusual causes of cirrhosis include defects of the bile ducts, HAEMOCHROMATOSIS (raised iron absorption from the gut), CYSTIC FIBROSIS, cardiac cirrhosis (the result of heart failure causing circulatory congestion in the liver), and WILSON’S DISEASE (raised copper absorption).
Symptoms Some people with cirrhosis have no signs or symptoms and the disease may be diagnosed at a routine medical examination. Others may develop jaundice, OEDEMA (including ascites – ?uid in the abdomen), fever, confusion, HAEMATEMESIS (vomiting blood), loss of appetite and lethargy. On examination, cirrhotic patients often have an enlarged liver and/ or SPLEEN, and HYPERTENSION. Liver function tests, cholangiography (X-ray examination of the bile ducts) and biopsy of liver tissue will help to reach a diagnosis.
Treatment Nothing can be done to repair a cirrhosed organ, but the cause, if known, must be removed and further advance of the process thus prevented. In the case of the liver, a high-protein, high-carbohydrate, low-fat diet is given, supplemented by liver extract and vitamins B and K. The consumption of alcohol should be banned. In patients with liver failure and a poor prognosis, liver TRANSPLANTATION is worthwhile but only after careful consideration.
Abscess of the liver When an ABSCESS develops in the liver, it is usually a result of amoebic DYSENTERY, appearing sometimes late in the disease – even after the diarrhoea is cured (see below). It may also follow upon in?ammation of the liver due to other causes. In the case of an amoebic abscess, treatment consists of oral metronidazole.
Acute hepatic necrosis is a destructive and often fatal disease of the liver which is very rare. It may be due to chemical poisons, such as carbontetrachloride, chloroform, phosphorus and industrial solvents derived from benzene. It may also be the cause of death in cases of poisoning with fungi. Very occasionally, it may be a complication of acute infectious hepatitis.
Cancer of the liver is not uncommon, although it is rare for the disease to begin in the liver – the involvement of this organ being usually secondary to disease situated somewhere in the stomach or bowels. Cancer originating in the liver is more common in Asia and Africa. It usually arises in a ?brotic (or cirrhotic) liver and in carriers of the hepatitis B virus. There is great emaciation, which increases as the disease progresses. The liver is much enlarged, and its margin and surface are rough, being studded with hard cancer masses of varying size, which can often be felt through the abdominal wall. Pain may be present. Jaundice and oedema often appear.... liver, diseases of

See cirrhosis.... liver, cirrhosis of
Liver problems appear as a sign of weakness shown by your organism after a prolonged consumption of alcohol, drugs or medicines.
The main characteristic of these affections is that they are due to system intoxication and need to be repaired as quickly as possible. The liver is the organ responsible for our molecular exhaustion.
All the toxins in our body go straight to the liver in order to clear the blood and detoxify the entire mechanism.
When the liver is not functioning well, the main symptoms are: fatigue, stress, vascular malfunction and irradiated pain from the liver area to the entire body. Unsolved liver problems may lead to kidney failure and then to pulmonary edema or other respiratory disorder.
How Tea for Liver Works
A Tea for Liver is a natural supplement that can calm your localized pain and bring relief to those suffering from this affection. The main ingredients of these teas are based on a great amount of nourishing substances that can reconstruct the damaged liver cells or at least increase their action.
However, these teas are not recommended for severe liver problems. If the pain is unbearable, a tea is most likely to calm it for a while and then lose its positive effect on your body. If that is the case, you should see a doctor immediately.
Efficient Tea for Liver
When choosing a Tea for Liver, you must keep in mind the fact that it must be safe and nourishing. You don’t need a tea that is rich in volatile oils or other substances that slow the liver cells’ action. If you are not sure about your abilities to choose the right tea, here are some suggestions:
- Green Tea – has all the necessary ingredients to sustain life. Also, its action includes nourishing the coronary system and the arteries, in order to enhance the blood flow through your organs
- Black Tea – more powerful than the Green Tea, the Black Tea is very effective, but more dangerous. If you’re also on your period or menopause, it’s best not to take it: it may cause abdominal acidity and discomfort.
- Yerba Mate Tea – or the new green tea, how the specialists are calling it. Yerba Mate Tea can be used as a cure in order to rejuvenate the liver, but also as a treatment in cases of low blood pressure or digestive tract infections. Pay attention, though: more than 2 cups of Yerba Mate Tea per day may lead to a series of nervous system complications and even death!
Teas you should avoid
If you are suffering from liver problems, it’s best to avoid taking a tea with an elevated level of vitamins or acids. Although vitamins get directly to your blood and none of them reaches the liver, they have a tendency to enhance your body’s action towards other affected areas.
In other words, they make your antibodies be more preoccupied with a random scratch than with your liver problems. A Tea for Liver needs to be specialized in internal affections and only attract antibodies to the most important damages.
Tea for Liver contraindications
When taken properly, any Tea for Liver is safe. However, high dosage may lead to a number of complications, such as diarrhea, nausea and even death.
If you’re not very sure about starting a treatment based on one of these teas, talk to a specialist in order to gather more information.
If there’s nothing that could interfere with your treatment, choose a Tea for Liver and enjoy its wonderful benefits responsibly!... tea for liver

Techniques for visualizing the kidneys, usually performed for diagnosis. Ultrasound scanning can be used to identify kidney enlargement, a cyst or tumour, and the site of any blockage. Conventional X-rays show the outline of the kidneys and most kidney stones. Intravenous urography shows the internal anatomy of the kidney and ureters. Angiography is used to image blood circulation through the kidneys. CT scanning and MRI provide detailed cross-sectional images and can show abscesses or tumours. Two types of radionuclide scanning are used for the kidney: DMSA and DTPA scanning. DMSA is a substance given by intravenous injection that binds to cells in the kidney tubule, giving a single, static picture of the kidneys. DTPA, also given intravenously, is filtered in the kidneys and passes out in the urine. Pictures taken at intervals record its passage through the urinary tract and show kidney function. ... kidney imaging
The liver is a common site of disease. The most significant liver conditions include alcohol-related disorders (see liver disease, alcoholic), hepatitis, and liver cancer. Disorders can also result from infection. Certain viruses cause hepatitis (see hepatitis, viral). Bacteria may spread up the biliary system to the liver, causing cholangitis or liver abscess. Parasitic diseases affecting the liver include schistosomiasis, liver fluke, and hydatid disease. Certain metabolic disorders, such as haemochromatosis and Wilson’s disease, may involve the liver. Other types of liver disorder include Budd–Chiari syndrome, in which the veins draining the liver become blocked. Occasionally, defects of liver structure are present at birth. Such defects principally affect the bile ducts; one example is biliary atresia, in which the bile ducts are absent. Because the liver breaks down drugs and toxins, damage to liver cells can also be caused through overdose or drug allergy.

(NAFLD) a spectrum of conditions affecting the liver in the absence of excessive alcohol consumption. NAFLD is a common cause of referral for patients with abnormal liver function tests. Fatty liver is excessive fat accumulation in the liver seen as an area of brightness within the liver on ultrasound examination. Fatty liver does not lead to irreversible liver damage in the majority of cases. Nonalcoholic steatohepatitis (NASH) is inflammation of the liver associated with accumulation of fat. It is often linked to insulin resistance, diabetes, hypertension, obesity, and *metabolic syndrome. Treatment involves dietary modification, regular physical exercise, weight reduction, and management of underlying conditions (e.g. diabetes, hypertension, and hiperlipidaemia). NASH may predispose to *cirrhosis and may ultimately require liver transplantation.... nonalcoholic fatty liver disease
the rapid acquisition and manipulation of ultrasound information from a scanning probe by electronic circuits to enable images to be produced on TV screens almost instantaneously. The operator can place the scanning probe accurately on the region of interest in order to observe its structure and appreciate moving structures within it (see Doppler ultrasound). Using similar techniques, the instantaneous display of other imaging modalities, such as *computerized tomography scanning and *magnetic resonance imaging, can now be achieved. Real-time imaging is useful in guiding *interventional radiology procedures, for example, allowing a needle to be guided accurately as it is passed into the body. It is also useful for observing dynamic physiological activity.... real-time imaging
a technique to image the parathyroid glands. Technetium is taken up only by the thyroid gland, but thallium is taken up by both the thyroid and parathyroid glands. *Digital subtraction of the two isotopes leaves an image of the parathyroid glands alone.
