| name | cross-reference-linking |
| description | Links current findings to priors, related literature, and correlated data. Use when user mentions "compare to priors", "find prior studies", "correlate with", "longitudinal comparison", or needs historical context. |
Cross-Reference Linking Skill
Triggers
- "compare to priors"
- "find prior studies"
- "correlate with"
- "longitudinal comparison"
- "followup from"
- "related findings"
- "pathology correlation"
Parameters
reference_type (required): Type of cross-reference needed
prior_studies - Historical imaging comparison
literature - Relevant published cases or studies
followup - Sequential study comparison
multimodality - Different modality correlation
pathology - Radiology-pathology correlation
clinical - EHR/clinical data correlation
finding_summary (required): Current finding to cross-reference
patient_id (optional): Patient identifier for prior search
date_range (optional): Time window for prior search
Cross-Reference Types
Prior Study Comparison
- Modality, date, and key findings of historical studies
- Size/dimension comparisons for measurable findings
- Density/signal intensity comparisons
- Change assessment (stable, improved, progressed)
Literature Correlation
- Similar published cases
- Expected imaging appearances
- Atypical presentations
- Prognostic implications
Pathology Correlation
- Common pathologies for imaging appearance
- Staging implications (TNM, etc.)
- Molecular markers and imaging correlates
- Treatment response patterns
Clinical Correlation
- Lab values relevant to imaging findings
- Symptoms and clinical history
- Treatment history and timeline
Output Format
Returns structured JSON with:
- Prior finding references with dates
- Comparison metrics (size, characteristics)
- Change assessment with confidence
- Recommendations for followup
- Related literature citations
Usage Examples
reference_type: prior_studies
finding_summary: 2.5 cm lung nodule right upper lobe
patient_id: MRN12345
reference_type: pathology
finding_summary: irregular spiculated mass left lower lobe
reference_type: followup
finding_summary: 1.2 cm thyroid nodule compared to 6 months prior
Data Sources
- PACS for prior imaging studies
- RIS for structured reports
- EHR for clinical correlation
- Literature databases for research correlation
- Pathology system for radiology-pathology correlation
