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

Figure 1 Acute osteomyelitis secondary to methicillin-resistant Staphylococcus aureus infection. A: Coronal T2-weighted image of the left humerus shows bone marrow edema (solid arrow) as well as a periosteal fluid collection (dashed arrow) consistent with periosteal abscess; B: Axial T1-weighted post-contrast image shows both enhancement of the bone marrow (solid arrow) as well as extensive periosteal and soft tissue abscess formation (dashed arrows) which is characteristic of methicillin-resistant Staphylococcus aureus infection.
