Thyroid disorders: automatic diagnosis in CONSULT I.
Automatic diagnosis of thyroid diseases is implemented on CONSULT I, a microcomputer system based on the Patrick model for computer-assisted diagnosis in medicine. The thyroid 'subsystem' consists of 19 classes (diseases) and 16 features (signs, symptoms, laboratory tests). For 76 test cases obtained from patient records (recognition samples), the 'true' class (disease) is decided in the highest 'probability' number in 89% of cases and in the differential diagnosis in 100% of cases. Performance is compared to physicians. Estimation of class-conditional probability densities utilizing equivalence regions in the feature space is discussed.
