Under optimal conditions xeromammography and filmmammography can reach about the same diagnostic accuracy. However because of the difficulty to detect xeroradiographically tiny microcalcifications filmmammography is to be considered as the optimal mammographic method provided it is carried out with rotating molybdenum anode and industrial type film for(More)
Frequent serious technical errors in mammorgraphy proved to be due to incomplete outlining of the breast, underexposure and blurring. These errors are in most cases secondary to incorrect positioning, absence or improper adjustment of automatic exposure system, insufficient quality of x-ray tube, and use of inappropriate films. Each mammogram should be(More)

502 breast cancers with 431 prevalent and 71 incident carcinomas and 3633 patients without breast cancer were classified according to the mammographic parenchymal pattern N1, P1, P2, Dy devised by Wolfe. The percentage of carcinomas in the various parenchymal groups were determined separately for prevalent and incident carcinomas divided by age groups. Risk(More)
With one-view mammography the detection rate for carcinoma would seem to drop considerably, in the screening situation for early carcinoma (T0 and T1) down to 50 to 60% under unfavourable conditions. The precentage of mammographic findings not completely cleared up by one-view mammography amounts to 54% among our patients. One-view mammography therefore(More)
Comparison of industrial film with long processing time and "90-second-Film" with film-screen combination showed the first type with long processing time to be distinctly superior. Number and shape of tiny clustered microcalcification were taken as criteria for correct visualization. Under present technical and geometrical conditions only industrial type(More)
