中枢神经系统CT影像诊断专家系统的设计与实现
Design and Implementation of the Central Nervous System CT Imaging Diagnosis Expert System
摘要
Abstract
Objective:To evaluate the clinical value of expert system of computer,which assisted by CT diagnosis in the central nervous system diseases. Method:According to imaging diagnosis observation habits,20 indicators were selected to establish the central nervous system imaging diagnosis library,and the initial values of the signs were seted in accordance with accepted probability of occurrence. The software of computer which assisted CT diagnosis in the central nervous system diseases was made by VFP9.0.173 misdiagnoses were selected from grade three and first-class hospitals which were proved by surgery and pathology. Two senior radiologists worked together as the first group,the CT images without the software were analyzed. The relative data were puted into the software by a senior radiologist as the second group and a junior radiologist as the third group ,then the results were geted from them. The statistical method χ²test was used in different group. Result:Diagnostic accuracy of the first group was 37.57%(65/173),the second group was 63.01%(109/173),and the third group was 46.89%(81/173). Statistical analysis showed that between the second group and other two groups the difference were statistically significant(P<0.05).Between the first group and the third group,the difference was no statistically significant(P>0.05).Conclusion:Expert system has important and practical value with the central nervous system CT imaging diagnostic.关键词
