RadteraXR Pelvis (AP)
XRNo contrastAbdomen & Pelvis
Indications
- Trauma/suspected pelvic or proximal femur fracture
- Hip pain/osteoarthritis
- Evaluation of SI joints and pubic symphysis
- Bony metastasis
- Pre-operative arthroplasty planning
Patient prep
- Remove clothing with radiopaque objects over pelvis; gown
- No preparation typically required
Contrast
None / non-contrast
Technique
- AP supine, legs internally rotated 15-20 degrees to place femoral necks parallel to IR (unless fracture suspected — do not rotate)
- CR perpendicular midway between ASIS and symphysis pubis (~2 inches inferior to ASIS level)
- SID 40 inches; grid; kVp ~75-85
- Suspended expiration
Series / Sequences
| # | Series / Sequence | Plane | Notes |
|---|---|---|---|
| 1 | AP | Frontal | Legs internally rotated 15-20 deg; CR to point midway between ASIS and symphysis; include both iliac crests and proximal femora |
Key points
- Do NOT internally rotate legs if fracture/dislocation suspected
- Frog-leg lateral (modified Cleaves) adds bilateral lateral hip evaluation
- Inlet and outlet (Pennal) views for pelvic ring trauma
- Judet (oblique) views for acetabular fractures
- Greater and lesser trochanters symmetric when properly positioned
