AI IN MEDICAL IMAGING
Transforming Endoscopic Reporting with Lesion-Aware AI
Automated image captioning for Ulcerative Colitis (UC) endoscopic examinations is revolutionized by a new lesion-aware AI framework. This innovation addresses the critical need for precise, interpretable, and diagnostically aligned reports, overcoming the limitations of previous models in identifying subtle, localized lesions.
Executive Impact: Precision, Efficiency, and Trust in AI-Driven Diagnostics
This advanced AI framework significantly enhances diagnostic accuracy and streamlines endoscopic reporting for ulcerative colitis, offering a clear competitive advantage in medical imaging. By providing detailed, lesion-aware captions and improved MES classification, it boosts clinical confidence and operational efficiency, setting new benchmarks for explainable AI in healthcare.

Lesion-Aware Visual-Language Fusion
The core of our innovation lies in integrating **ResNet embeddings**, **Grad-CAM heatmaps**, and **CBAM-enhanced attention** with a **T5 decoder**. This framework specifically emphasizes pathological regions by directly incorporating Grad-CAM maps into the encoder. Clinical metadata like MES scores, bleeding, and vascular patterns are embedded as natural language prompts, guiding the T5 decoder to generate structured, interpretable, and diagnostically aligned reports for ulcerative colitis endoscopic examinations. This multi-modal fusion ensures high contextual accuracy and consistency.
Unprecedented Accuracy & Interpretability
Our model achieves an impressive **84.7% MES classification accuracy**, surpassing previous state-of-the-art by a significant margin. For captioning, it reached **BLEU-4 0.87** and **ROUGE-L 0.85**, demonstrating superior linguistic quality and semantic relevance. A paired bootstrap resampling confirmed statistical significance (p < 0.01) over baselines. This breakthrough is attributed to the lesion-aware modulation and semantic conditioning, which allow the AI to pinpoint subtle disease markers often overlooked by standard methods, fostering greater trust in AI-driven diagnostics.
Real-world Clinical Impact
The framework produces **visual-attentive reports** with lesion-focused heatmaps and a structured summary of findings (MES score, lesion type), directly assisting clinicians in **real-time interpretation, reporting, and integration with electronic medical records (EMR)**. This interpretability is crucial for clinical adoption. Future work includes extending the approach to **video colonoscopies**, exploring **real-time deployment** with optimized inference times (1.45 seconds per image), and incorporating **feedback loops** for continuous model refinement and building clinician trust.
MES Classification: Setting a New Standard
Our lesion-aware AI achieves unprecedented accuracy in classifying the Mayo Endoscopic Subscore (MES), a critical metric for ulcerative colitis severity.

Case Study: Real-Time Diagnostic Support
Scenario: A gastroenterologist performs a colonoscopy on a patient with suspected UC. As images are captured, our AI framework provides **instant, structured captions** and **MES score predictions** with visual heatmaps highlighting active inflammation.
Impact: The clinician instantly confirms findings, ensures **consistent terminology** for reporting, and identifies subtle mucosal damage potentially missed during rapid examination. This significantly **reduces report generation time** and enhances the **precision of treatment planning**.
Outcome: The clinic experiences improved diagnostic workflow, **reduced inter-observer variability**, and higher patient satisfaction due to clear, explainable reports. This leads to better patient outcomes and more efficient resource allocation.
