[The use of the Daylight System in mammography].
It is widely known that Daylight film handling has yielded several benefits to diagnostic radiology, that is, reduction in exam duration, thus improving both efficiency and productivity; space saving in departments, by minimizing darkroom spaces; improved working conditions for the staff. This paper reports on the study of the application of a Daylight system to mammography. For this purpose, the authors used an X-ray unit (Senographe 500 T-CGR) and a Dupont Daylight unit, whose diagnostic yield was compared to that of "vacuum" and cassettes units. The results of our experience confirmed the well-known advantages DDS yields to diagnostic radiology. In particular, the use of Daylight rather than vacuum system allowed a considerable reduction in exam duration (10 to 2 minutes). Moreover, the new Dupont screen-film system allowed a reduction in average whole breast dose by about 28% if compared to the conventional recording system employed in our department. Mammograms with high contrast resolution, sensitivity, and good spatial resolution were thus obtained, as shown in the analysis of quality image. The Daylight system allowed a marked improvement to be made in efficiency, productivity, and organization, as well as a reduction in whole breast dose and high-quality mammographic images.
