[Breast xeroradiography (author's transl)]

Breast xeroradiography is a new radiological technique based upon the electrostatic and not the photographic properties of silver bromide. We have used it particularly with reference to breast disorders in order to compare it to traditional procedures and to seek the best conditions to obtain the most informative picture by comparing the radiation emitted by a tungsten anode with the radiation emitted by a molybdenum anode with molybdenum or aluminium filtration. We concluded the xeroradiography was of value in breast problems in the following instances: 1. For certain types of microcalcification. 2. For the precise study of the relation of the breast to the chest wall. 3. For breast with a uniform high density on conventional films (young organ, fibro-glandular hyperplasia, after high-dosage irradiation). 4. In the study of deep seated carcinomas or those in the sub-mammary fold. 5. In studying the axilla where the ribs, muscles and nodes are seen together on the same film. Comparative study of xeroradiography using either a tungsten or molybdenum anode was markedly in favour of the latter under all the circumstances mentioned above.
