1. Clinical Summary
Series Phase Coverage CT Pelvis Contrast (N/A or 60s if contrast delay) Iliac crests to Proximal femurs - Pelvic fracture
- Sacral fracture
- SI joint
- Pelvic ring injury
- Pre-operative planning
-
2. Patient Prep
- Position: Supine
- NPO Status: N/A
-
3. IV Contrast & Injection
Parameter Value Agent None typically. Contrast if infection 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 to proximal femurs. Submillimeter for 3D. Assess pelvic ring integrity. Inlet and outlet views
- Additional Recons: 3D pelvis. Inlet and outlet views. Young-Burgess classification. Measure displacement
- No IV unless contrast indicated
Safety First
- Renal Function: N/A or eGFR > 30
- Allergy: N/A or check allergy
- Pelvic ring fractures (Young-Burgess). Sacral fractures (Denis). Acetabulum. SI joints. Symphysis pubis
- Submillimeter for 3D pelvic reconstruction
