- The HEPAR system is a medical expert system developed as a supportive tool for the diagnosis of disorders of the liver and biliary tract. In the system, the use of information from the medical interview and physical examination, supplemented with the results of generally available diagnostic techniques, such as ultrasound, is emphasized. Medical knowledge is recorded in the system using production rules. In an evaluation of the system, in which retrospective data from 94 patients were used, a diagnostic conclusion was reached in 84 of all cases; 80 of these final diagnoses were correct.
