Figure 2From: Subchondral fracture of the femoral head after acetabular fracture: a case report Magnetic resonance images show a bone marrow edema pattern. (A) Coronal T1-weighted magnetic resonance (MR) image shows a diffuse low-intensity signal in the proximal portion of the femoral head. (B) T2-weighted fat-suppression MR image shows diffuse high-intensity signals in both the proximal and medial portions of the femoral head.Back to article page
