CT Sinus Stereotactic

Last Updated: 2026-01-01 Author:

  • 1. Clinical Summary

    Series Phase Coverage
    Stereotactic Sinus Non-contrast Frontal sinus to Hard palate
    • Pre-operative sinus surgery planning
    • Image-guided surgery
    • ENT surgical navigation

  • 2. Patient Prep

    • Position: Supine head-first. Surgical planning position
    • NPO Status: N/A

  • 3. IV Contrast & Injection

    No Intravenous Contrast

    This protocol does not require IV contrast administration.

  • 4. Special Notes

    • Submillimeter isotropic acquisition. DICOM for surgical navigation system. May need fiducial markers. Entire sinus anatomy
    • Additional Recons: Export DICOM to surgical navigation system. Isotropic 0.625mm
    • Position as for surgery. Fiducials if required

    Safety First

    • Renal Function: N/A
    • Allergy: N/A
    • Complete sinus anatomy for surgical navigation. Ostiomeatal complex. Skull base. Lamina papyracea
    • Isotropic voxels essential. DICOM for navigation
