Utility description: Xe-127 Theranostic Potential Analyzer

Xe-127 Theranostic Potential Analyzer — Xe-127 Theranostic Potential Analyzer

ℹ️  Utility evaluates Xe-127 suitability for theranostics:
    • Diagnostic contrast and resolution
    • Patient radiation dose
    • Logistics potential (half-life)
    • Theranostic index

⚠️  CRITICAL: Balance between image quality and dose!
    Long half-life of Xe-127 requires strict dose control.

Usage:
  Xe127TheranosticPotentialAnalyzer.exe                            → demo mode (console output)
  Xe127TheranosticPotentialAnalyzer.exe input.csv output.json      → evaluate your data

Input format:
BatchNumber,ProductName,Contrast_Ratio,Resolution_mm,Dose_uSv_per_MBq,Bio_Half_Life_h,Phys_Half_Life_h,Cost_Usd,Max_Dose,Min_Contrast

Example:
  THERA-XE127-001,Xe-127 Agent,15,2.5,2.5,0.5,36.4,150,5,10

— WHY IS THIS NEEDED?
Theranostic potential assessment is critical for new isotope implementation:
• Xe-127 combines diagnostic properties (gamma emission) and therapy potential (at high doses or in combination)
• Long half-life (36.4 days) makes it ideal for logistics but increases radiation safety requirements
• Utility helps find balance between diagnostic value and patient safety
• Theranostic index calculation allows comparing Xe-127 with other agents (e.g., Xe-133 or Tc-99m)

⚠️  CRITICAL:
• High imaging contrast (≥10:1)
• Low effective dose (<5 uSv/MBq)
• Fast biological clearance from lungs
• Economic viability of production

Key features:
• Comprehensive diagnostic and therapeutic suitability assessment
• Logistics scoring based on half-life
• Economic efficiency evaluation
• Support for various clinical protocols

Critical parameters:
• Contrast Ratio: ≥10
• Effective Dose: ≤5 uSv/MBq
• Logistics Score: ≥80
• Theranostic Index: ≥5.0

💡 Usage tips:
1. Use clinical trial data to calibrate contrast parameters
2. Account for regional radiation safety requirements in dose calculation
3. Compare logistics potential with short-lived analogs (Ga-68, F-18)
4. Optimize production process to reduce dose cost
5. Maintain theranostic index log for different lung pathologies

⚠️ Note: Unlike pure diagnostics, here isotope potential as part of complex therapy is evaluated. Long half-life of Xe-127 is both an advantage (logistics) and a challenge (dose). The utility helps quantitatively assess this compromise.
