It can often be difficult to describe digital pathology without getting too technical. However, it is rapidly gaining momentum as a proven and essential technology; with specific support for education, tissue-based research, drug development, and the practice of human pathology throughout the world.  <\/p>

Digital pathology is an innovation committed to the reduction of laboratory expenses and an improvement of operational efficiency. It enhances productivity and improves treatment decisions and patient care.<\/p>

What is Digital Pathology?<\/strong><\/span><\/h2>

Digital pathology is a sub-field of pathology that focuses on data management based on information generated from digitized specimen slides. It is a dynamic, image-based environment that enables the acquisition, management, and interpretation of pathology information generated from a digitized glass slide.<\/p>

Digital pathology utilizes virtual microscopy through the use of computer-based technology. Glass slides are converted into digital slides that can be viewed, managed, shared, and analyzed on a computer monitor. With the practice of Whole-Slide Imaging (WSI), which is another name for virtual microscopy, the field of digital pathology is growing and has applications in diagnostic medicine.<\/p>

Its goal is to achieve efficient and cheaper diagnoses, prognoses, and prediction of diseases due to the success of machine learning and artificial intelligence in healthcare.<\/p>

Digital pathology incorporates the acquisition, management, sharing, and interpretation of pathology information \u2014 including slides and data \u2014 in a digital environment. Digital slides are created when glass slides are captured with a scanning device, to provide a high-resolution digital image that can be viewed on a computer screen or mobile device.<\/p>

Evolution of Digital Pathology<\/strong><\/span><\/h2>

The evolution of digital pathology, or whole slide imaging (WSI), has taken almost 20 years and is quite similar to that of the mobile phone. It has progressed from attaching a camera to the lens of a microscope to the development of the first scanners to what we have today: technology that is quickly becoming indispensable in the anatomic laboratory.<\/p>

The first scanners were clunky instruments taking up large footprints \u2013 with long processing time (up to 6 minutes) expensive storage, and limited use cases. Scanners today can scan slides in as little as 30 seconds. They can also be configured at multiple magnifications and handle up to 1,000 slides at a time. Storage, now available in the cloud, is affordable, secure, and accessible. Computational applications incorporating artificial intelligence (AI) offer a myriad of ways to analyze and present images to the pathologist.<\/p>

With the evolution of whole-slide image scanners, digital pathology as a practice has taken off.<\/p>

How Does Digital Pathology Work?<\/strong><\/span><\/h2>

Digital pathology is the process of digitizing glass slides using a whole slide image scanner and then analyzing the digital images using an image viewer, typically on a computer monitor or mobile device. An image viewer works similarly to the traditional standard light microscope. This enables pathologists to move slides around in the same way. <\/p>

Lab technicians scan glass slides using whole-slide imaging scanners. A pathologist can then view, manage, share, and analyze the digitized slides on a computer monitor in addition to or as a replacement for a microscope. The pathologist will use digital pathology software to view, store, manage digitized slides, and share the images with colleagues. Analysis tools help them study and diagnose the digitized slides on a computer. Their case management software can integrate with or replace existing workflows, like a Laboratory Information System (LIS), to make the process as seamless as possible. Finally, they create a report of their analysis that they send to the physician.  <\/p>

Although the basic viewing functionality has not changed drastically, it has brought about amazing advancements in pathology lab efficiency, workflow, and revenue enhancements.<\/p>

How is Digital Pathology Used?<\/strong><\/h2>

There are three main ways in which digital pathology is used today. <\/p>

First, research institutions, such as pharmaceutical companies, CROs, and academic medical centers. It also uses digital pathology in robust study design, data collection, and database management for the millions of specimens that it currently manages and seeks to leverage. <\/p>

Second, clinical labs use digital pathology on select cases for remote consultations, education, or quantitative analysis.<\/p>

The third and fastest-growing use case centers on clinical labs moving to an all-digital workflow. These labs use computational-enabled digital pathology powered by AI to help assign cases to pathologists, manage the workflow into worklists, offer quantitative image analysis for specific case types, integrate information into their existing Lab Information System (LIS), and expand access to cases beyond the brick-and-mortar walls of the lab itself. <\/p>

With digital pathology, diagnosis no longer needs to be delayed by the physical shipment of tissue samples or the wait times that result when pathologists are out of the office.<\/p>

Advantages of Digital Pathology<\/strong><\/h2>

In conventional histopathology, the physical transfer of glass slides from the laboratory to the pathologist is a prerequisite for the analysis. The pathologist then analyzes one slide at a time using a light microscope. By using digital pathology and whole slide imaging, it is possible to avoid usual transport processes and to simultaneously analyze several slides. <\/p>

Digital pathology makes it possible to rapidly and simultaneously analyze several regions of a tissue section in any magnification. Using various digital tools, including annotations, measurements, and counts, it is possible to analyze clinical and morphological changes in a more detailed and in-depth way.<\/p>

Digital pathology allows on-screen quantification of predictive and diagnostic biomarkers, which is beneficial for rapid and accurate decision-making. The provision of artificial intelligence applications further improves the quality of pathology services. <\/p>

Various algorithms have been developed for on-screen image analysis, including pattern recognition algorithms. Computer-guided image analysis tools have been developed to quantify disease biomarkers, providing all pathologists with the same index for scoring pathological findings and classification of diseases. <\/p>

The easy and rapid process of sharing digital information makes it possible to consult with other pathologists across the world (telepathology). This network between pathologists is particularly vital for the clinical fields where only a few specialists are available. <\/p>

Furthermore, digital pathology has opened up more flexible and remote job opportunities for pathologists and other medical personnel.<\/p>
