title: [Radiodiagnosis of pathologic processes of the stomach using EDP as a diagnostic aid].
abstract: The use of EDP makes it possible to increase the accuracy of the radiodiagnostics of the stomach. The retrospective study is based on 540 X-ray examinations of benign and malignant processes of the stomach which had been diagnosed histologically. It can be proved by means of examination findings that the use of the multivariate discriminatory analysis allows a reliable analysis of the manifold interrelations between the various classes of diagnosis on the one hand and diagnostically usable sign patterns on the other hand so that, in the majority of the classes of diagnosis, the degree to which the diagnostic information issued will increase in comparison to the empirically established radiodiagnoses. The reclassification resulted in the following correct assignments to the various classes: ulcus ventriculi, benign 87 per cent; ulcus ventriculi, malignant - 78 per cent; exulcerated carcinoma - 82 per cent; polyp, benign - 85 per cent; polyp, malignant - 75 per cent; polypoid carcinoma - 91 per cent; stenosis, benign - 85 per cent; stenosis, malignant - 79 per cent; infiltrating carcinoma - 63 per cent. Preconditions for the practical application of EDP in the radiodiagnostics of the stomach are an examination technique and method which exhaust all the available technical possibilities, and an exact interpretation of the radiographic signs.
