Paper Abstract

Laboratory comparisons of the resolution, noise, and contrast of five mammography screen-film systems (single screen, single-emulsion film) were made both qualitatively and quantitatively. Subjective single-blind estimations of resolution, noise, and contrast were also made directly from the mammograms of 100 consecutive patients radiographed with each of the screen-film systems. Laboratory and clinical evaluations showed strikingly similar results: improved contrast, minimally reduced resolution, and varying degrees of increased noise for the faster recording systems. Similarities between the results of laboratory and clinical studies should help to establish the clinical relevance of the laboratory analyses, and recognition of the relative precision of the clinical evaluations should allow for their use in place of laboratory studies when sophisticated physics support is not available.
