Pros & Cons of Digital Pathology
Objectives
• Review benefits of digital imaging in Pathology
• Discuss the challenges of Digital Pathology
• Recommendations & future trends in the field
Why did KODAK go BANKRUPT?
• They did not go digital
• Thought it was just a fad
• Failed to consider the benefits (e.g. applications)
• Stuck with what they always did

Versatile WSI Scanners
• Images glass slides from 3" x 1" to 8" x 6"
• Whole mount specimens

Digital Pathology UsesPantanowitz. J Pathol Inform. 2010;1: 15
• Primary diagnosis• 2nd opinion (consultation)• Telepathology• Quality Assurance (PT)• Archiving & Sharing• Education/Conferencing• Image analysis• Research & Publications• Marketing & Business• Track (audit) & Training
Telepathology Benefits
Clinical advantages• Access to pathology experts• Improved patient care
Operational gains• Easier to move images• Encourages consultation
Business rewards• Increased potential revenue
• Digitization of images ushers in a new world of computational analysis.
• Computational analysis opens up a whole new world of digital imaging.

Barriers to Adoption
Imaging Step Key Problem
Pre-imaging Lack of standardization
Image acquisition Scan fail rate
Image management No DICOM adoption
Image viewing Unlike microscopy
Image analysis Heterogeneity & artifacts
Relationship between slide quality & image quality in WSI

Digital PathologySustainable or Disruptive Innovation?
• In general, most new products marketed fail.
• Companies innovate faster than customers’ can change.
• Products too good, expensive & inconvenient for users.
