Introduction and objectives: In the laboratories of the Microbiology department, histological sections of tissues affected by parasites are presented, which run the risk of breaking easily due to constant manipulation. The large number of students observe only the microscopic field selected by the professor and do not have the possibility of reviewing the microscopic pathophysiological alterations in the organs. The advent of robotic microscopes capable of scanning and digitizing complete glass slides is an alternative to achieve more dynamic laboratories required by 21st century students. Unlike conventional digital image files that feed virtual classrooms, which typically contain a single view, Whole Slide Imaging (WSI) files are formatted as multi-resolution pyramids that allow real-time viewer performance to be optimized and images can be easily shared over the Internet (1–4).
The aim of the study was to evaluate the subjective impression of medical students regarding the use of WSI in two parasitology cases.
Methods: Medical students from 5th to 10th semester were evaluated, two slides from the parasite biopsy collection of the Microbiology course were digitized and a clinical case was created for each one. Indications for use, cases and WSIs were sent by e-mail. An online survey was applied using a Likert scale ranging from 1 to 5, evaluating photo quality and the behavior and functionality of the tool by the student.
Results: 60% of the students evaluated with very easy (5) to open, zoom and scroll through the WSI and 60% with easy (4) to find and identify the parasite. 80% are interested in learning how to handle the tool.
Conclusions: The WSIs were very well evaluated by the students and generated interest in their use in the future.
