The digital path: how digital technology and AI are redefining pathology and disease detection

Pathology is a powerful yet often overlooked field of medicine, where meticulous analysis of cells and tissues under a microscope unlocks crucial diagnoses and shapes treatment plans for patients.

A new era of precision and speed

For decades, the pathology process was largely manual. Tissue samples, meticulously prepared on glass slides, were the pathologist’s universe. Obtaining a second opinion involved physically transporting these delicate slides, a process prone to delays and even damage. “Before digital pathology, seeking a second opinion meant physically sending the samples for consultation,” Dr Lozano explains. “There was a risk of the delicate slides being lost or damaged.”

Today, high-resolution scanners convert these physical slides into digital images, accessible instantly from anywhere. “Pathology is undergoing a fundamental transformation fuelled by digitalisation,” says Lee Lehman-Becker, Head of Healthcare Insights at Roche. “This digital transformation is fuelled by the need to provide patients across the globe with best-in-class diagnostic results, regardless of their geography and access to medical professionals and specialists.”

Breaking down barriers, building collaboration

The Clínica Universidad de Navarra in Pamplona, Spain, is one of the hospitals leading this digital transformation. Dr Lozano attests to the immediate impact: “In our experience, digital pathology increases the pathology’s productivity. We save time.”

Beyond efficiency, digital pathology fosters unprecedented collaboration. “With digital pathology we can share cases with more expert pathologists, be more accurate and ask in some cases, especially in difficult cases, for help.” This means a patient in Pamplona can benefit from the expertise of a specialist across the globe, simply by sharing a digital image.

The power of AI – beyond the human eye

Perhaps the most transformative aspect is the integration of AI and image analysis algorithms. AI-based digital tools provide “more specific information that doesn’t rely anymore on the subjectivity of our eyes on the microscope,” notes Dr Lozano. AI can detect subtle patterns and anomalies that are sometimes invisible to the human eye, offering deeper insights and more precise diagnoses for patients. “I hope that in the future, digital pathology will help us predict things our eyes are unable to detect.”

This blend of human expertise and digital innovation is not just making diagnostics faster; it’s making them smarter, more accurate and globally connected. As Dr Lozano states, “Everything that helps us make a better diagnosis will improve patient care and the healthcare system overall.”

Digital pathology is paving the way for a healthier future, one precise diagnosis at a time.
