The challenge

What we found.

A leading academic medical center's pathology department was processing 2,400+ tissue samples daily for cancer detection. Manual microscopy review faced significant challenges, including inter-observer variability of 12–18% between pathologists.

Each slide required 15–20 minutes of expert review, creating an 8-hour turnaround for urgent cases and a growing backlog that threatened research timelines. They needed to augment (not replace) their experts with AI-assisted screening.

The approach

How we built it.

PRR developed a computer vision pipeline using custom-trained models:

  • Ensemble of YOLOv8 and custom segmentation models trained on 180,000 annotated images
  • Integration with 4 different microscopy systems and slide scanners for seamless ingestion
  • Human-in-the-loop workflow where AI flags regions of interest for pathologist final determination
  • Full audit trail and traceability for regulatory compliance
