Virtual microscopy (VM) is being utilized as an educational tool in many areas of pathology. The aim of this study is to analyze the locator and diagnostic skills of cytotechnology students by using the Aperio T3 ScanScope, and examine VM's viability as an educational tool in cytotechnology. Ten validated cytology slides were digitized and reviewed by three senior cytotechnologist instructors. Each technologist made annotations indicating diagnostic areas on the virtual slide. A subset of the slides was used for locator skill evaluation. Cytotechnology students examined a pristine copy of the virtual slide and made annotations for comparison to those made by experienced instructors. Annotations of the subset were then scored based on the degree of correlation between students and cytotechnologists. A cytopathologist performed a final review of the students' marks; points were then added or subtracted based on this interpretation. Students were graded based on their correlation to senior cytotechnologists. A statistical analysis using modified interrater calculations ranked the students as to locator ability, producing illuminating results. This study shows that VM has promise as a cytotechnology educational tool by allowing the instructor to evaluate students' locator and diagnostic abilities. We have attempted to implement a simple scoring system for evaluation of locator skills where students are compared versus expert cytotechnologists. We anticipate further technological improvements as the products mature.
虚拟显微镜(VM)正被用作病理学许多领域的一种教育工具。本研究的目的是通过使用Aperio T3 ScanScope分析细胞技术专业学生的定位和诊断技能,并检验VM作为细胞技术教育工具的可行性。选取了10张经过验证的细胞学玻片进行数字化处理,并由三位资深细胞技术教师进行审阅。每位技术人员在虚拟玻片上做出指示诊断区域的注释。其中一部分玻片用于定位技能评估。细胞技术专业学生检查虚拟玻片的原始副本并做出注释,以便与经验丰富的教师所做注释进行比较。然后根据学生与细胞技术人员注释之间的相关程度对该部分的注释进行评分。一位细胞病理学家对学生的评分进行最终审核;然后根据此审核结果进行加分或减分。根据学生与资深细胞技术人员的相关性对学生进行评分。使用改进的评分者间计算方法进行的统计分析对学生的定位能力进行了排名,得出了有启发性的结果。本研究表明,VM有望成为一种细胞技术教育工具,因为它能让教师评估学生的定位和诊断能力。我们尝试实施一种简单的评分系统来评估定位技能,即将学生与专业细胞技术人员进行比较。随着产品的成熟,我们预计会有进一步的技术改进。
