Modern technology of ultrasound helps to accuratelyassess the size and shape of the liver, identify neoplasms in it, for example, cyst or liver cancer, evaluate the structure and density of the parenchyma in diffuse lesions, etc.
Recently, ultrasound is widely used as a method that helps to choose the best access for abdominal drainage, liver biopsy and other manipulations.
Ultrasound of the liver is considered a simple, inexpensive and rapid method of examining the structure of this organ. There are several cases where ultrasound is performed:
At the same time, the preparation of a liver uzi is quite simple.
3 days before the day when the liver ultrasound is performed,the patient should be excluded from eating black bread, milk, vegetables and fruits, sweet juices and other products that contribute to the appearance of gases in the intestine. In meteorism, enzyme preparations (panzinorm, festal, etc.) and adsorbents (chamomile infusion, activated charcoal, etc.) should be prescribed.
On the eve of the study, in the evening and just before the procedure in the morning, two cleansing enemas should be placed. However, this procedure is not considered mandatory if the patient does not have flatulence.
Before research it is necessary to remove ornaments, and also a part of clothes.
When ultrasound of the liver is performed, it is required to lie down onthe couch. To facilitate the procedure, a slightly heated gel is applied to the skin. Using a small hand-held sensor, which is carried along the body in different directions, the doctor scans the organs, the images of which appear on the monitor.
The study is done on the breath holding during inspiration, at which point the liver is slightly lowered and becomes more accessible for visualization.
Thus, it becomes possible to visualize the left and right lobes of the liver, as well as other digestive organs.
When the ultrasound of the liver is carried out, the doctor drawsattention to large vessels (for example, a portal vein), to the uniformity of the structure of the liver, to small vessels, to the biliary tract, and also measures the size of the lobes of the liver.
When carrying out ultrasound of the liver, decoding is of great importance.
In general, ultrasound is considered an orienting methoddiagnosis of diseases, which establishes not the disease itself, but those changes in the tissue of the organ that may well appear against the background of some disease. The totality of all the changes that are established during the ultrasound and the symptoms that are observed in the patient makes it possible to speak with certain certainty about the presence of any disease in the patient.
Ultrasound of the liver usually ends with a scan of the abdominal cavity to detect free fluid in it.
Ideally, the contours of the liver should be even and clear throughout the entire length.
Thus, for a good ultrasound pictureliver characterized by the presence of non-intensive, small, relatively distant from each other echoes, between them echo-negative spaces remain.
The most common diffuseliver damage can include hepatitis (chronic and acute), liver cirrhosis and fatty dystrophy. The correct diagnosis when performing ultrasound of the liver is highly dependent on a large number of subjective and objective reasons. The first of these can include the type of device, its resolving power, sensitivity, the presence of certain factors that degrade the image (gassing in the intestine, obesity, etc.). The professionalism of the specialist and the care in carrying out the research are of great importance.
