Xeroradiography

Xeroradiography can be called a promising and effective method for diagnosing both oncological diseases and the condition of the thyroid gland. The method is based on the combined use of x-ray and fluorographic research methods. Unfortunately, due to the fact that research based on the use of ionizing radiation does not have sufficient resolution, the method is used primarily for diagnosing tumors. A series of automated xero-radiographic equipment (KROZ) devices has been developed, which make it possible to obtain images of a narrow beam field of a body area in the form of narrow raster images with high resolution. In this case, the radiation exposure during the study is reduced by 25–50 times or less compared to conventional fluorography and x-ray mammography. The subject performs appropriate manipulations on the subject at the command of the doctor or laboratory assistant, including turning the body over. The disadvantage of this method is the low contrast of the image due to the presence of natural gray melanin coloring on the skin. Because of this, the ability to differentiate dense tissue formations from fatty tissue is significantly impaired. Research results have shown 92–94% accuracy of the method in many clinical cases.
