title: Non-invasive diagnosis of carotid stenoses: results of some methods of investigation.
abstract: In this paper the results are presented of four 'first-generation' non-invasive methods of diagnosing carotid stenosis. They are given in the form of ROC curves, showing the dynamic relationship between their sensitivity and specificity. For the interpretation of the combined results of different methods the consecutive application of the rule of Bayes is used. Proceeding from an estimated pre-test probability of 40%, a post-test probability of the disease can be calculated. This depends on a particular combination of positive or negative test results and can range from highly probable to (99%) extremely improbable (1%).
