A Taxonomic Index for Retrieval of Digitized Whole Slide Images from an Electronic Database for Medical School and Pathology Residency Education

Abstract

Since the advent of whole slide imaging, the utility of digitized slides for education in medical school and residency has been amply documented. Pathology departments at most major academic medical centers have made digitized slides available to pathology residents for study, even before the use of digitized slides for clinical purposes (i.e., primary diagnosis) has become commonplace. This article describes the experience of one academic medical center with the storage and indexing of large volumes of digitized slides. Our goal was to be able to retrieve scanned slides for a variety of educational applications and thereby maximize the heuristic value of the slides. This posed a formidable challenge in terms of development and deployment of an index system that would allow exemplary slides to be identified and retrieved irrespective of the purpose for which the slide was scanned. We used the structure inherent in Aperio's image management software (eSlide Manager) to build an educational database that allowed each image to be appended with a unique taxonomic identifier so that the individual files could be retrieved in a flexible and utilitarian manner.

Biobanking in the digital pathology era

“…This file can be stored in a database and easily available to any researcher from a computer screen. In this approach, due to the advances in AI, the use of digital microscopy is increasing for either educational or research purposes [38][39][40][41][42]. Moreover, WSI can be utilized in image analyses by integrating deep learning models for identification and segmentation [43,44].…”

Digital Era and Artificial Intelligence in Pathology: Basic Information

“…Birçok merkezde kurulmuş olan dijital patoloji sistemi hâlen, uzaktan konsültasyon, kalite kontrolü, araştırma ve eğitim gibi aktivitelerde kullanılmakta olup, rutin tanı ve prognoz tespiti için uygun olup olmadığı test edilmektedir. 1,3,6,14,18,[22][23][24] Örneğin Avrupa'daki bazı örneklerinde aynı olgu için hem rutin hem de dijital slaytlar hazırlanmakta, patoloji uzmanları olguları istedikleri yöntemi kullanarak ve bazen her ikisi ile birden incelemektedirler. 13,25 İsveç'te, Kalmar ve Linköping Hastanelerinde 2008'den 2014'e >500.000 lam rutin uygulama için taranmış olup, tüm patoloji uzmanları dijital incelemeyi ergonomik yönden yararlı bulmuş ve patoloji uzmanlarının büyük kısmı (%90) görüntü kalitesinin yeterli olduğunu bildirmiştir.…”
