What does B-ultrasound check

B-ultrasound is a common method of diagnosing diseases in radiology. It mainly targets various organs and sections. With a certain sense of period, it is mainly to conduct some research and utilize the principles of ultrasound. To scan the human body. The main B-ultrasound uses a common B-ultrasound, color B-ultrasound and some other types of B-ultrasound. It is mainly used for cross-sectional scanning of various clinical organs and surrounding organs.

At the same time, it can clearly discover some difficult and complicated diseases, as well as the openness of blood vessels, the direction and speed of blood flow. It can also be widely used. Many liver and kidney diseases in daily life can also be shown in B-ultrasound.

In clinical applications, B-ultrasound can clearly display various cross-sectional images of internal organs and surrounding organs. Since the images are full of solidity and close to the real anatomical structure, ultrasound can be used to make a clear diagnosis at an early stage. For example: When ophthalmologists diagnose non-metallic foreign bodies, retinal and retrobulbar lesions can be displayed in the presence of vitreous opacities. It is specific for non-invasive detection of congenital heart disease, rheumatic heart disease, and myxomatous disease of the heart and can replace most cardiac catheterization examinations. It can also be used to measure the patency of small blood vessels, blood flow direction and speed, and can be widely used. Early detection of liver space-occupying lesions has reached the 1 cm level. It can also clearly display the gallbladder, common bile duct, hepatic duct, extrahepatic bile duct, pancreas, adrenal gland, prostate, etc. B-ultrasound examination can detect whether there are space-occupying lesions, especially the physical characterization, quantity and volume of effusions and cysts, which are quite accurate. The detection rate of various intraluminal stones is higher than that of traditional examination methods. It has also solved many difficult problems in obstetrics that were difficult to detect in the past. For example, it can locate the placenta, measure amniotic fluid, and make early diagnosis of single or multiple births, fetal development, malformations, and hydatidiform mole.

(1) Gallstones: The diagnostic rate of B-ultrasound for gallstones is over 90%, and stones as small as 3 mm in diameter can be detected. Although the diagnosis rate of bile duct stones is not as high as that of gallbladder stones due to the interference of intestinal gas, changes such as bile duct dilatation and thickening of the bile duct wall caused by bile duct stones can be seen.

(2) Cholecystitis: Cholecystitis can cause changes in the size and wall of the gallbladder. In acute cholecystitis, B-ultrasound may show enlarged gallbladder and diffuse thickening of the cyst wall; in chronic cholecystitis, the gallbladder may swell or shrink, with thickened walls and rough edges.

(3) Biliary tract tumors: The ultrasound image of benign gallbladder tumors appears as a semicircular or nearly circular, bright mass with uniform structure; the mass of malignant tumors is irregular in shape, uneven in density, and the gallbladder wall is thickened and uneven; the sonogram of cholangiocarcinoma appears as an irregular mass in the middle of the bile duct, and the bile duct above the mass is often dilated and thickened.

(4) Biliary ascariasis: Ultrasound images show strips of ascariasis light parallel to the bile duct, and even the peristalsis of the ascariasis can be seen.

(5) Obstructive jaundice: The normal inner diameter of the extrahepatic bile duct is generally less than 6 mm, and the inner diameter of the left and right hepatic ducts is less than 2 mm. If the B-ultrasound shows a value greater than the above, it indicates that the bile duct is blocked, and the bile duct above the obstruction appears dilated and thickened. Therefore, the site of the obstruction can be determined, and sometimes the cause of the obstruction can also be provided.

The above is what B-ultrasound checks. It clearly displays various cross-sectional images of various organs and surrounding organs, as well as the openness of blood vessels and the direction and speed of blood flow for diseases. It can also be widely used. Therefore, B-ultrasound examination is also a relatively common examination method. B-ultrasound can also be performed during pregnancy, so it is also a common treatment method in daily life.
