X-ray characteristics of mammary gland changes

The technical problems on the X-ray presentation of the mammary gland are discussed. The role of film mammography and electroroentgenography for detection of the structural changes in the gland is emphasized. The roentgenomorphologic characteristics of the most common X-ray shadows in the mammary glands, classified by their intensity, form, size, number, structure and arrangement, is presented. For a more rapid and easier characterization of the changes in the different mammary gland diseases, the author developed a practicable work formula. This formula is a decimal fraction, in whose numerator are written the morbidly altered numerically marked quadrants of the right mammary gland and in the dominator - those of the left. This formula is suitable for presentation both of diffuse and of solitary changes in the gland. A brief description of their types is given after the formula. The practical value of the formula for the diagnosis of mammary gland diseases is pointed out. It helps the roent--genologist and the surgeon in the exact localization of the changes and performance of an exact sectorial resection. This, in turn, furnishes better opportunities for the pathologist to gain access exactly to the morbidly altered area, which is of particular importance for detection of intraductal cancer. The convenience of the work formula for a rapid recognition and schematic designation of the findings and in mass prophylactic mammofluorographic screening of women is emphasized. (author)
