title: [A daylight film development system for mammography. Report of clinical experience after 4000 examinations (corresponding to 14,000 mammographies].
abstract: From 6/90-2/91 the daylight system EC (Fuji Ltd.), developed only for mammography, was used in the Department of Gynaecological Radiology of the Radiological Centre of the University of Freiburg for the first time in Germany. We examined 4000 patients (respectively 14,000 mammographies). We controlled the quality of the x-ray photographs every day (n = 175) and compared the results with the controls of quality, which had been carried out from 9/89-5/90 with the conventional technique (n = 175). During the entire period of research (9/89-2/91) at both systems the results of Dmin were inferior to the standard. Using the daylight system the measurements of the index of sensitivity were in 91% of the cases (n = 160), and the index of contrast in 88% (n = 154) within the range--much better than with the conventional system with 74% (130 measurements), respectively 70% (123 measurements). We also found an evident advantage of time and in future it is to be expected that the conventional system will be replaced by the daylight system in mammography.
