title: [An intra- and interobserver study of the accuracy of dynamic CT of hepatic space-occupying lesions].
abstract: An intra- and interobserver study with 10 physicians was undertaken in order to determine the accuracy of differentiation regarding the type and benign/malignant of hepatic space-occupying processes. By "conditioning" of the observers a significant reduction of doubtful cases with a slight increase in diagnostic accuracy (10% in differentiating of benign/malignant and 5% of the type) relative to our first study was achieved. Marked increases were found for 3 little experienced observers. By informing the observers on the diagnostic criteria for hepatocellular carcinoma the percentage of correct decisions was significantly increased.
