Anterior Pelvis Bones Study

Superoinferior axial “Inlet” Projection

1. Patient in supine position;
2. Lower limbs in extension.

Central ray angled 45º caudal to the middle between Anterior Superior Iliac Spine (ASIS) and pubic symphysis.

Respiration: Suspended.

Evaluation Criteria:

• Good visualization of the pelvic;
• Symphysis pubic in axial projection;
• Visualization of the hip joint;
• Appropriate exposure values (visualization of the all bony trabeculation and soft tissue).

AP Axial “Outlet” Projection

1. Patient in supine position;
2. Lower limbs in extension.

Central ray angled 45º cephalad to the middle between Anterior Superior Iliac Spine (ASIS) and pubic symphysis.

Respiration: Suspended.

Evaluation Criteria:

• Pubic bones superimposed by the sacrum;
• Symmetry of the obturator foramen;
• Visualization of the hip joint;
• Appropriate exposure values (visualization of the all bony trabeculation and soft tissue).
