Examples

Example 1: BI-RADS Report

Generate a BI-RADS 4A report for a spiculated mass

**Left Breast:**
- 2 o'clock: 15mm spiculated mass with suspicious calcifications

**Assessment:**
BI-RADS: 4A - Low suspicion for malignancy

**Recommendations:**
Ultrasound-guided biopsy recommended

Example 2: Free-Text to Structured

Convert: "CT chest shows 2.5cm mass in right upper lobe. No mediastinal lymphadenopathy. Suspicion for malignancy."

**Findings:**
- Lungs: 25mm spiculated mass, right upper lobe
- Mediastinum: No lymphadenopathy

**Assessment:**
- Lung mass, concerning for malignancy

**Recommendations:**
- PET/CT for staging
- CT-guided biopsy
