Abstract

A total of 110 diaphanograms from women with breast carcinoma and 154 diaphanograms from women with benign breast disorders were quantitatively evaluated using the OSIRIS image scanner. Optical density values in the green and red spectral bands were recorded. The malignant and the benign groups, were statistically evaluated using linear discriminant analysis. Correct classification was obtained in 73.5 per cent of women with breast carcinoma and in 84.6 per cent of women with benign breast disorders. Visual interpretation of the findings alone classified 84.5 per cent of the malignant lesions correctly and 90.8 per cent of the benign lesions correctly. Quantitative evaluation combined with visual interpretation improved the accuracy of classification of breast carcinoma (91.8%), but not of benign breast disorders, which was about the same (83.8%).
