PURPOSE
One possible limitation of structured template radiology reports is that radiologists look back and forth between viewing and dictation monitors, thereby impacting the length of time spent reviewing images and generating a report. We hypothesize that the total time spent viewing case images is diminished and/or the total time spent creating a report is prolonged when the report is generated using a structured template compared with free text format.
APPROACH
Three neuroradiologists and three senior residents viewed five brain magnetic resonance imaging cases with unique findings while eye position was recorded. Participants generated reports for each case utilizing both structured templates and free text dictation. The time spent viewing images was compared with the time spent looking at the dictation screen.
RESULTS
The two main hypotheses were confirmed: the total time viewing images diminished with templates versus free text dictation and the total time to create a report was prolonged with templates. The mean time (s) spent on the "image" region of interest approached statistical significance as a function of the report type [free: attendings = 236.79 (154.43), residents = 223.55 (77.79); template: attendings = 163.40 (73.42), residents = 182.48 (77.47)] and was overall lower with the template reporting for both attendings and residents ( , ), but it did not differ as a function of seniority ( , ).
CONCLUSIONS
Template-based radiology reports have significant potential to alter the way radiologists view images and report on them, spending more time viewing the report monitor rather than diagnostic images compared with free text dictation. Many radiologists prefer templates for reporting as the structured format may aid in conducting a more systematic or thorough search for findings, although prior work on this assumption is mixed. Future eye-tracking studies could further elucidate whether and how templates and free reports impact the detection and classification of radiographic findings.
目的
结构化模板放射学报告的一个可能局限性在于，放射科医生需要在查看影像和听写监视器之间来回切换，从而影响查看影像和生成报告所花费的时间。我们假设，与自由文本格式相比，使用结构化模板生成报告时，查看病例影像的总时间会减少和/或生成报告的总时间会延长。
方法
三名神经放射科医生和三名高级住院医师查看了五例具有独特发现的脑部磁共振成像病例，并记录了他们的眼睛位置。参与者使用结构化模板和自由文本听写为每个病例生成报告。将查看影像所花费的时间与查看听写屏幕所花费的时间进行比较。
结果
两个主要假设得到证实：与自由文本听写相比，使用模板时查看影像的总时间减少，生成报告的总时间延长。根据报告类型，在“影像”感兴趣区域花费的平均时间（秒）接近统计学显著性[自由文本：主治医生 = 236.79（154.43），住院医师 = 223.55（77.79）；模板：主治医生 = 163.40（73.42），住院医师 = 182.48（77.47）]，总体而言，主治医生和住院医师使用模板报告时该时间都更低（ ， ），但与资历无关（ ， ）。
结论
与自由文本听写相比，基于模板的放射学报告有显著潜力改变放射科医生查看影像和报告的方式，即花更多时间查看报告监视器而非诊断影像。许多放射科医生更喜欢使用模板进行报告，因为结构化格式可能有助于更系统或全面地查找发现，尽管此前关于这一假设的研究结果不一。未来的眼动追踪研究可以进一步阐明模板和自由报告是否以及如何影响影像学发现的检测和分类。
