CT Hip

Last Updated: 2026-01-01 Author:

  • 1. Clinical Summary

    Series Phase Coverage
    CT Pelvis/Hips Contrast (N/A or 60s if contrast delay) Iliac crests to Proximal femurs
    • Hip fracture
    • Acetabular fracture
    • Femoral neck
    • Pre-operative planning
    • FAI assessment

  • 2. Patient Prep

    • Position: Supine
    • NPO Status: N/A

  • 3. IV Contrast & Injection

    Parameter Value
    Agent None typically. Contrast if infection/mass
    Volume If contrast: 100 mL
    Flow Rate 2-3 mL/s

    Use full dose if GFR > 30

    If GFR < 30

    Max Contrast = \(2*\left[\frac{\text{Patient Weight}}{75 \text{ kg}} * \text{eGFR}\right]\)

  • 4. Special Notes

    • Iliac crests through proximal femurs. Bilateral for comparison. Submillimeter for 3D acetabular reconstructions
    • Additional Recons: 3D pelvis. Judet oblique views. Letournel classification. FAI measurements (alpha angle)
    • No IV unless contrast indicated

    Safety First

    • Renal Function: N/A or eGFR > 30
    • Allergy: N/A or check allergy
    • Femoral neck fractures. Acetabular fractures (Judet/Letournel). Hip dislocation. FAI morphology. AVN
    • Bilateral coverage. Submillimeter for acetabular 3D
