# Multimodal Radiology-Pathology Fusion Agent

The **Multimodal Radpath Fusion Agent** integrates diverse clinical data sources including radiology imaging (CT, MRI, PET), digital pathology whole slide images, genomic profiling, and electronic health records using state-of-the-art multimodal deep learning for comprehensive cancer diagnosis, treatment response prediction, and prognostic modeling.

## When to Use This Skill

* When integrating radiology and pathology for unified tumor assessment.
* For treatment response prediction using multimodal imaging.
* To predict molecular features from imaging (imaging genomics).
* When building comprehensive prognostic models.
* For tumor board decision support with AI second opinion.

## Core Capabilities

1. **Radiology-Pathology Fusion**: Integrate macro and microscopic views.

2. **Imaging-Genomics Correlation**: Predict molecular features from imaging.

3. **Treatment Response Prediction**: Multi-modal response modeling.

4. **Survival Prediction**: Comprehensive prognostic models.

5. **Tumor Characterization**: Integrate phenotype from all modalities.

6. **Clinical Decision Support**: AI-assisted tumor board recommendations.

7. **Dermatology and Dermoscopic Image Triage**: Evaluate clinical and dermoscopic images for basal cell carcinoma and common mimickers as multimodal LLM decision support, with explicit image-quality constraints, differential diagnosis limits, and clinician-overread safeguards.
