Contrast in X-ray diagnostics

X-ray diagnostics is a research method that uses X-rays to obtain images of human internal organs and tissues. This method is one of the most common and accurate ways to diagnose various diseases. However, to get a complete picture of the condition of the organs, it is necessary to use special contrast in radiography.

Contrast is a substance that changes the optical properties of the body and makes it more transparent to x-rays. This allows you to see hidden structures of organs even with a low dose of radiation. The contrast can be administered to the patient orally, inhaled or intravenously. It is important that the contrast is not harmful to health and is quickly eliminated from the body after cessation of exposure.

There are several types of contrast that are used in x-ray diagnostics. For example, barium is a white powder that breaks down in the body into barium salt, which is highly permeable to x-ray waves. Barium is used to examine the stomach, intestines and other abdominal organs. Novocaine - used for X-ray contrast examination of vessels, such as the aorta and its branches. Iodine-containing agents are also used as a contrast, for example, iodine triiodide and prorovanium. These contrasts are used in the study of the liver, kidneys and biliary tract.

High image clarity and contrast make radiography one of the most popular research methods not only for diagnosis, but also for monitoring the dynamics of changes in organs after treatment. The use of contrast in radiology greatly facilitates the diagnosis of many diseases, since it allows one to detect small details such as
