[Use of computer-aided x-ray diagnosis in oncology (author's transl)]

The introduction of computer-aided diagnostic reveals new perspectives for diagnostic decisions. The results of the hitherto used mathematical diagnostic models are represented. The Bayes's theorem as the most used model exhibited very different, in parts unsatisfactory results. More convenient seems to be multivariate models, like discriminant analysis. Hitherto the computer-sided diagnostic was used in a relative small number of differential diagnostic problems. There are yet many replying questions. It is necessary to compare the efficiency of the different mathematical-statistical methods and to search for optimal solution ways for all differential diagnostic problems.
