Whole-slide imaging: widening the scope of cytopathology

Abstract Whole slide imaging (WSI) is broadening the scope of cytopathology. Whole slide images are being used for telecytology, quality assurance activities (e.g. proficiency testing) and teaching (e.g. digital teaching sets and online virtual atlases). Progress in WSI technology that permits high resolution scanning, z-stacking, and hybrid robotic devices has encouraged the use of this imaging modality for cytology practice, education and research. However, widespread adoption in cytology still depends on overcoming barriers unrelated to cytology and challenges directly related to digitizing cytopathology slides. The aim of this article is to review WSI technology, applications and limitations specific to cytopathology.
