DEVELOPMENT OF A KNOWLEDGE-BASED IMAGE REPORTING SYSTEM

我们构建了一个原型结构化报告系统，取代了医学图像报告的传统口述和转录。主要设计特征包括报告速度、图形报告的生成、成像发现的结构化存储以及现有词典的使用。试点定时数据表明，放射科医生使用我们的系统可以生成一个报告比传统的报告方法或语音识别系统更快。正在寻求支持，以完善原型，并进行可行性测试。具体目标是（1）增加和完善成像术语的分层测试词典（2）开发成像结果及其逻辑关系的表示和报告方法，（3）评估系统在临床成像报告上的性能，以及（4）评估现有成像词典的完整性。该项目得到由关键方法领域专家组成的技术咨询委员会的支持。一个成功的第一阶段将导致（在第二阶段）测试的方法，横截面成像，通过，增强，并使用现有的词典，实时决策支持技术的基础上，由系统生成的成像结果的知识库的建设，并在临床环境中的系统评价。拟议的商业应用：我们的结构化报告系统对放射科医生很有吸引力，因为与传统的听写/转录或语音识别相比，它加快了报告过程。此外，该系统消除了与转录服务相关的成本、延迟、不准确性和其他组织问题，从而改善了患者护理。因此，高效的语音增强结构化报告系统可能会在每年12亿美元的放射学转录服务市场中占据相当大的份额。

We have constructed a prototype structured reporting system that replaces conventional dictation and transcription for medical image reporting. Key design features include reporting speed, generation of graphical reports, structured storage of imaging findings, and the use of existing lexicons. Pilot timing data suggest that a radiologist using our system can generate a report more rapidly than with conventional reporting methods or speech recognition systems. Support is sought to refine the prototype, and to conduct feasibility testing. The specific aims are (1) to augment and refine a hierarchical test lexicon of imaging terms (2) to develop methods for the representation and reporting of imaging findings and their logical relationships, (3) to evaluate the system's performance on clinical imaging reports, and (4) to assess the completeness of existing lexicons for imaging. The project is supported by a Technical Advisory Committee comprised of experts in key methodological areas. A successful Phase I will lead (in Phase II) to testing of the approach for cross-sectional imaging, to adoption, augmentation, and use of an existing lexicon, to construction of real-time decision support techniques based on the knowledge base of imaging findings generated by the system, and to system evaluation in a clinical setting. PROPOSED COMMERCIAL APPLICATIONS: Our structured reporting system is appealing to radiologists because it speeds up the reporting process compared to conventional dictation/transcription or speech recognition. In addition, the system eliminates the costs, delays, inaccuracies, and other organizational problems associated with transcription services, thereby improving patient care. Therefore, time-efficient, speech-augmented structured reporting systems will likely capture a significant segment of the $1.2 billion annual market for radiology transcription services.
