Luobukaweike treats chronic second liver

Be in all sorts of video in learning to check a technology, CT can reflect hepatic pathology configuration performance most, if have inside the size shape of focus of a disease, place, amount and focus of a disease,do not have haemorrhage necrotic, calcify. From the brim of focus of a disease the circumstance can understand his to invade a gender, if brim of focus of a disease is smooth clear, show coating especially, show tumor grows relatively slow, if tumor border is punch-drunk,invade sexual small; , show tumor has taller descent quality, easy encroach blood vessel, or cancerous bolt is formed inside portal vein. The former liver cancer that send a gender can divide commonly according to general pattern for 4 model: Gigantic piece model: Cancerous organization submits chunk form, can be individual gigantic piece, the diameter is in 5cm above, also can become by a lot of concentrated nodal confluence, can have sometimes all round its come loose smally in tubercle, call huge chunk satellite; tubercle model: Cancerous tubercle can be individual or many, size differs, distributing in liver left, right leaf, also know exactly about sth nodal confluence becomes 　 of a bigger nodal; huge cake section (mix model) : Point to gigantic a companion individual or 　 of; of many nodal focus of a disease diffuses model: This model the scarcest, whole liver has diffuse the petty cancer that distributing is nodal. The growth that presses tumor means, there are two kinds of kinds on pathology, one kind is infiltration grows model, one kind is to expand grow model. Plan bound is not clear between former focus of a disease and liver essence, border of latter focus of a disease of brim faintness; is clear, or coating having a holiday is formed, these two kinds of types have different show on CT. Cancer of the liver often violates vein system, portal vein relatively liver vein and vein finishing speech more often be encroached. Vein suffers encroach can cause cancer the move inside swollen liver and form tumour bolt and fistula of activity arteries and veins. The liver cancer that grows around liver door often encroachs bile duct, bring about block sex icteric. Lymph node is transferred and many seeing, the lymph node after door of liver of main drag in and peritonaeum. Cancer of the liver can encroach adjacent organ directly. Move can cause ascites of courage and uprightness to peritonaeum, far is transferred with lung the commonnest. Cancer of the liver can produce spontaneity haemorrhage, form haematoma falls with coating inside liver or cause celiac internal haemorrhage. The CT expression of the former liver cancer that send a gender depends on not only the pathology of tumor sheds kinetic characteristic with blood, still with all round the liver organization condition that did not violate is concerned. CT is smooth sweep expression of great majority liver cancer to be low density, namely density of focus of a disease (CT is worth) relatively all round normal liver essence is relatively low, also can be wait for density or mix density, smooth sweep cannot discover. The person that high density is spent is very few, constant companion has fatty liver. Normally the focus of a disease of ≤ 1cm, the density difference with liver essence is very little, smooth sweep check to go out rate is very low (20%-40%) . When cancer of the liver and the density difference that normal liver organizes are lesser, need to use narrow window and adjust a window observation. But with narrow the window can bring about false positive. Density of cancer of the liver constant inhomogenous, lower density area is seen in low density focus of a disease, for sex of necrotic, bursa changes inside focus of a disease or adipose and metamorphic be caused by. The CT value of adipose and metamorphic area often is less than - 10Hu. Internal haemorrhage of focus of a disease is scarcer, expression is low density there is spot in focus of a disease piece shape high density spends an area. The density of a few liver cancer is evener, this is common at lesser and necrotic and unidentified the liver cancer that show. The liver cancer that is located in liver periphery can make the outline limitation apophysis of liver. The brim of cancer of the liver is mostly ambiguous and not only whole, there can be space to show picture of strip low density inside cancerous kitchen. Expand grow model focus of a disease, no matter nodal or gigantic piece model, attrib border all clear, major coating having a holiday exists, on CT expression is circuit is low all round tumor the annulus shadow of density (namely dizzy annulus asks for) , ply can differ to 1cm from several Mm, it is especially in small liver cancer commonner. The coating on pathology is formed by fibre. The prognosis of the person that have coating relatively the person that do not have coating is good. When discovering because of the liver cancer that does not have coating, although lesser, but often already bolt of the cancer inside portal vein and its branch is formed. The calcify of cancer of the liver is not common, can submit concentrated drop record, radiation shape, line shape or irregular form. Groovy CT examination goes after increasing, the low density focus that expression of major liver cancer heightens to spend aggrandizement door gently to have) or not aggrandizement, as a result of all round aggrandizement of normal liver organization is more apparent, it is more clear that reason shows to the configuration of focus of a disease, size.
