-
1. Clinical Summary
Series Phase Coverage Low Dose Chest N/A Lung apices → Costophrenic angles - Non Contrast chest for patient's age < 60
-
2. Patient Prep
- Position: Supine with arms raised
- NPO Status: N/A
- Pre-Medication:
- None required
-
3. IV Contrast & Injection
No Intravenous Contrast
This protocol does not require IV contrast administration.
-
4. Special Notes
- LOW DOSE technique. Reduced mAs 30-50% of standard. Helical acquisition. High IR strength
- No IV. Explain screening purpose and low radiation
