Non-Volumetric HRCT 1 Respiratory Phase

Last Updated: 2026-01-01 Author:

  • 1. Clinical Summary

    Series Phase Coverage
    HRCT Inspiration Non-Contrast (Full inspiration delay) Lung apices to Costophrenic angles
    • HRCT follow-up
    • Known ILD monitoring
    • Bronchiectasis assessment

  • 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

    • Single INSPIRATION phase. Non-volumetric (1-2cm intervals). Lower dose for follow-up
    • Additional Recons: Target slices through abnormality. Compare to prior
    • No IV. Single inspiration breath hold

    Safety First

    • Renal Function: N/A
    • Allergy: N/A
    • Follow ILD changes. Bronchiectasis. Lower radiation than volumetric
    • Non-volumetric reduces dose. Good for follow-up
