A label-free optical imaging technique using autofluorescence lifetime and AI can distinguish colorectal cancer with 85% accuracy.
Key Details
- 1Champalimaud Foundation researchers developed a fiber-optic, label-free optical imaging method for colorectal tissue analysis.
- 2Technique involves autofluorescence lifetime measurements at two wavelengths to capture biochemical differences.
- 3Machine learning (AdaBoost) trained on 117 patients' surgical specimens, validated with matched pathology results.
- 4On test data, the AI achieved 85% accuracy, 85% sensitivity, and 85% specificity.
- 5Potential applications include real-time cancer detection during colonoscopy or surgery, reducing the need for biopsies.
- 6Simplified versions of the imaging system delivered strong results, supporting future clinical use.
