DIGITAL and COMPUTATIONAL PATHOLOGY

The Ohio State University Wexner Medical Center is home to one of the world’s leading digital pathology programs.

Daily over 2,400 slides are digitized and made instantly available to our pathologists who use them for primary diagnosis, consultation, education, and research. In 2018, Ohio State became the first site in the United States to utilize digital pathology for primary diagnosis. Today, most of our sign-outs are digital.

Digital allows our pathologists to share their knowledge and skills to help patients around the state and across the globe. The use of digital images allows us to erase time and distance and provide pathology review in real time hundreds or even thousands of miles away.

We are proud to also be a leader in deploying quantitative image analysis (QIA), machine learning, and artificial intelligence to produce diagnoses for patients that are dramatically faster, more comprehensive, and more accurate than ever previously possible. We work with our partners to develop, test, and implement the tools that will transform pathology in the 21st Century.

Digital pathology has also enabled our teams to expand our research capabilities. Our research lab assists scientist with using digital resources and tools to probe the nature, causes, consequences, and treatment of disease in ways never before possible. Digital allows our researchers to assemble cohorts more rapidly, inquire of larger volumes of cases, and interrogate specimens more deeply, faster, and more accurately than ever before.

As a consequence of our endeavors, we manage one of the world’s largest collections of whole slide images (WSI). Ohio State is home to almost 2.7 million WSIs, representing over 280,000 patients, and every imaginable tissue and disease type.

FACILITIES

multiple scanners in our scan center

OSUCCC / OSU Pathology Scan Center

The OSUCCC – James Digital Pathology team of experts is dedicated to detecting and diagnosing cancer accurately and quickly. Our team’s mission is to work with researchers and physicians to provide answers to research questions—simple and complex—using the most sophisticated technology available.

The digital pathology process begins with whole-slide imaging, or scanning conventional glass slides and then using sophisticated technology to join consecutive images digitally into a single, whole image—replicating the information on the glass slide.

  • (8) Philips Ultra Fast Scanners. Largest collection of such scanners in the country.
  • Scan approximately 2500 slides a day
  • Operational 24hrs a day / 5 days a week
  • All slides are scanned at 40x magnification
  • Each slide consist of apprximately 1GB of information
  • Cancer Data Trust

Validation of digital pathology systems:

  • CAP Validation completed for all 7 production Scanners for primary diagnosis scanning
  • In progress: Whole mount Scanning for prostate and penile cancers
  • Pdx External consults (since March 1): 782
  • PDx cases (since March 1): 988
  • Retrospective Cancer cases from thru Late 2013, 2014, 2015, 2016 & 2017 done and upto June 2018
  • More than 720,000 Slides have been scanned
  • More than 63,000 Cases are now available online
  • First site in the US to go live with primary diagnosis

Adoption of digital pathology:

  • Tumor Boards & Conferences
    • 37 Weeks of GYN tumor boards ( Used by Dr. Suarez, Dr. Li, Dr. Ivanov, Dr. Chen)
