EP4.12 MRI Versus CT-Based Three-Dimensional Reconstruction for Quantifying Cam Morphology with Alpha and Omega Angles
Abstract Background Cam morphology of the proximal femur is three-dimensional (3D), yet it is commonly summarized using single-plane alpha-angle measurements. Omega angle is an angle that quantifies the circumferential arc of cam deformity around the femoral head–neck junction. 3D Magnetic Resonance Imaging (MRI) may a...
