Role of MRI in the diagnosis and treatment of osteomyelitis in pediatric patients

Figure 2 Early acute osteomyelitis. A: Coronal proton-density weighted image of the right ankle of a 12-year-old male shows a subtle area of decreased intramedullary signal along the lateral aspect of the calcaneus (long arrow); B: Axial T2-weighted image with fat suppression demonstrates more conspicuous bone marrow edema (arrowhead); C: Coronal post-contrast T1-weighted image with fat suppression shows an area of enhancement corresponding to the bone marrow edema. Bone biopsy revealed bacterial osteomyelitis.
