[Significance of roentgen symptomatics of 425 breast carcinomas in 10000 mammographies (author's transl)].

The diagnostic significance of 425 carcinomata of the breast compared with NAD mammographs is examined according to 16 main criteria. Size of the breast, type of tumorous densification, structural changes parenchymal patterns, and prominent duct patterns, are analyzed in greater detail besides the often discussed direct and indirect signs of malignancy. By paying attention to discreet roentgenographic changes, the rate of false negative findings can be reduced. Mammographic examinations on only one level result in a reduction in correct diagnoses of breast carcinoma by at least 8%.
