Expert systems are application tools based on logic and containing a wide knowledge in a specific field; their aim is the simulation of an expert's behavior in reasoning and making decisions inherent a small cultural domain. Applications in medicine and radiology are numerous and constantly increasing. The possibility of their use in the application of diagnostic and staging protocols seems particularly interesting. The development and commercial availability of expert systems programming tools (called shells) make it certainly easier to develop consultations systems, even to non-experienced users. The purpose of this research is the definition and description of the stages encountered during the development of an expert system for diagnosis, staging and treatment of bladder cancer using self-developed shell, designed for radiological use, called Experto. The steps of knowledge collection, definition of diagnostic and therapeutic protocols and system development are described. The consultation system assessed the correct TNM stage of the 27 examined cases.
专家系统是基于逻辑的应用工具，在特定领域拥有广泛知识；其目的是模拟专家在特定小文化领域进行推理和决策的行为。医学和放射学领域的应用众多且不断增加。它们在诊断和分期方案应用中的使用可能性似乎特别有趣。专家系统编程工具（称为外壳）的开发和商业可用性无疑使开发咨询系统变得更容易，即使对于没有经验的用户也是如此。本研究的目的是定义和描述使用自行开发的、专为放射学使用而设计的名为Experto的外壳开发膀胱癌诊断、分期和治疗专家系统过程中所遇到的阶段。描述了知识收集、诊断和治疗方案定义以及系统开发的步骤。该咨询系统评估了27例受检病例的正确TNM分期。
