[The value of xeroradiographic patterns in the diagnosis of breast diseases (author's transl)].
The purpose of this study was to establish the value of xeroradiographic patterns and their applicability in the automatic diagnosis of breast diseases. Such an evaluation is based on the comparison with the histologic examination, irrespective of the overall diagnostic judgement previously formulated. From an analysis of the material examined it was possible to ascertain the distribution frequency, the sensitivity, the specificity, the discriminating capacity, and finally the weight of each radiologic sign considered. There are xeroradiographic signs that are apparent almost exclusively in the malignant pathology and therefore can be considered as positive indices of the malignancy of the alteration. The specificity of the radiologic signs considered is very high, whereas the same cannot be said for the sensitivity. Moreover, a linear discriminating analysis made it possible to identify those semiologic elements which, with a minor probability of error, would attribute the pathologic process to the class verified histologically, for malignant neoplasms as well as benign tumors and dysplastic processes.
