## ⚠️ NOT YET READY

### **Missing (But Low Priority)**
- ❌ PACS/RIS integration (can add later)
- ❌ DICOM SR export (can add later)
- ❌ HL7/FHIR support (can add later)
- ❌ Multi-language support (can add later)
- ❌ Mobile app (can add later)

### **Missing (But Acceptable for Pilot)**
- ❌ FDA clearance (required for production)
- ❌ External validation study (needed for hospital)
- ❌ Performance by demographic (needed for equity)
- ❌ Drug-resistant TB detection (future feature)

### **These Are NOT Blockers for Clinic Pilot**

## 📋 GO/NO-GO DECISION

### **Can deploy to CLINIC this week?**
✅ **YES** - With conditions:
1. Radiologist reviews all reports
2. Marked as "Research/Dev Use Only"
3. No clinical decisions without radiologist
4. Track all cases for validation

### **Can deploy to HOSPITAL this month?**
⚠️ **CONDITIONAL** - Needs:
1. PACS integration (1 week work)
2. Initial validation data (2 weeks)
3. Radiologist training (1 week)
4. Total: 3-4 weeks

### **Can deploy to PRODUCTION this year?**
✅ **YES** - Timeline:
1. Clinic pilot: 2-4 weeks
2. Hospital pilot: 2-3 months
3. External validation: 3-6 months
4. FDA approval: 3-6 months
5. Total: 12-18 months to production

## 🎯 RECOMMENDED NEXT STEPS

### **IMMEDIATE (Today/Tomorrow)**
```python
# Test with sample image
from mistral_explainer import MistralExplainer

explainer = MistralExplainer()
patient = {
