Radiation exposure of the breast in film- and xero-mammography.
In addition to other advantages, xeoradiography, compared with film-mammography, seems to result in a lower radiation dosage to the breast. In order to get some valid information concerning this point, depth dose measurements, were carried out in a plexiglas phantom for the different radiographic factors used in film- and xero-mammography. It could be shown that the exposure of the skin and the mean exposure of the breast are generally lower in xero-mammography than in film-mammography, and that this difference increased with increasing thickness of the breast. Therefore it can be concluded that xero-mammography should be preferred on account of its lower radiation exposure, whenever it is possible from the diagnostic point of view.
