title: [Analysis of the difference between the results of complex mammography and histology-- a contribution to the sensitivity and specificity of mammography].
abstract: Of a total of 18,500 mammographic examinations of our own patients, 1393 diagnosis had been confirmed by histology. In 89 cases (6.39%) where x-ray diagnosis did not agree with histological findings, we re-assessed the mammographies retrospectively. 29% of the false negative diagnosis proved retrospectively to be due to errors on the part of the examiner, whereas in the remaining 24 patients the carcinoma of the breast could be visualized by mammography (3.8% of all histologically confirmed malignomas). In the 41 false positive findings the x-ray symptoms "focus with radial ramifications" and "microcalcifications" were the most frequent causes of performing a diagnostic extirpation. Sensitivity of the mammographic method in identifying a carcinoma was 94.8% and the specificity 94.6%. The causes of erroneous assessment are discussed and the need for performing complex diagnosis of the breast is underlined.
