  • 1. Clinical Summary

    Series Phase Coverage
    Ultra Low Dose Chest Non-contrast Lung apices to Costophrenic angles
    • Pulmonary nodule follow-up
    • Known nodule surveillance

  • 2. Patient Prep

    • Position: Supine with arms raised
    • NPO Status: N/A

  • 3. IV Contrast & Injection

    No Intravenous Contrast

    This protocol does not require IV contrast administration.

  • 4. Special Notes

    • ULTRA LOW DOSE 10-20% standard dose. For follow-up of KNOWN nodules only. Not for initial detection. Maximum IR
    • No IV. Known nodule follow-up only

    Safety First

    • Renal Function: N/A
    • Allergy: N/A
    • Follow known nodules. Compare to prior. Measure size. Not for initial detection
    • Ultra low dose. Maximum IR. Prior comparison essential
