[The appropiate film for mammography (author's transl)]

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 film with long processing time gives high diagnostic accuracy in early breast cancer which depends to a large degree on proper delineation of microcalcifications.
