Internet-based search engines have become a significant component of medical practice. Physicians increasingly rely on information available from search engines as a means to improve patient care, provide better education, and enhance research. Specialized search engines have emerged to more efficiently meet the needs of physicians. Details about the ways in which radiologists utilize search engines have not been documented. The authors categorized every 25th search query in a radiology-centric vertical search engine by radiologic subspecialty, imaging modality, geographic location of access, time of day, use of abbreviations, misspellings, and search language. Musculoskeletal and neurologic imagings were the most frequently searched subspecialties. The least frequently searched were breast imaging, pediatric imaging, and nuclear medicine. Magnetic resonance imaging and computed tomography were the most frequently searched modalities. A majority of searches were initiated in North America, but all continents were represented. Searches occurred 24 h/day in converted local times, with a majority occurring during the normal business day. Misspellings and abbreviations were common. Almost all searches were performed in English. Search engine utilization trends are likely to mirror trends in diagnostic imaging in the region from which searches originate. Internet searching appears to function as a real-time clinical decision-making tool, a research tool, and an educational resource. A more thorough understanding of search utilization patterns can be obtained by analyzing phrases as actually entered as well as the geographic location and time of origination. This knowledge may contribute to the development of more efficient and personalized search engines.
互联网搜索引擎已成为医学实践的重要组成部分。医生越来越依赖搜索引擎提供的信息，以改善患者护理、提供更好的教育和加强研究。专门的搜索引擎已经出现，以更有效地满足医生的需求。关于放射科医生如何使用搜索引擎的细节尚未记录。作者按放射学亚专业、成像方式、访问的地理位置、一天中的时间、缩写词的使用、拼写错误和搜索语言对放射学为中心的垂直搜索引擎中的每 25 个搜索查询进行了分类。肌肉骨骼和神经成像是最常搜索的亚专业。最不常搜索的是乳腺成像、儿科成像和核医学。磁共振成像和计算机断层扫描是最常搜索的方式。大多数搜索都是在北美发起的，但所有大陆都有代表。搜索以转换后的当地时间 24 小时进行，大多数搜索发生在正常工作日期间。拼写错误和缩写很常见。几乎所有的搜索都是用英语进行的。搜索引擎的使用趋势可能反映出搜索来源地区的诊断成像趋势。互联网搜索似乎是一种实时的临床决策工具、研究工具和教育资源。通过分析实际输入的短语以及起源的地理位置和时间，可以更深入地了解搜索使用模式。这些知识可能有助于开发更高效和个性化的搜索引擎。
