Imaging of osteomyelitis and musculoskeletal soft tissue infections:: current concepts
Section snippets
Conventional radiography
Plain radiographs are the first step in the imaging assessment of osteomyelitis because they may suggest the correct diagnosis, exclude other pathology, or provide clues for other pathologic conditions. The earliest sign is the deep soft tissue swelling of muscles and superficial subcutaneous soft tissues. Bone destruction and periosteal reaction are not early findings, but when seen, the infectious process has been present and active for more than 1 or 2 weeks. Comparative views of the
Summary
The diagnostic imaging of osteomyelitis can require the confluence of multiple imaging technologies. Conventional radiography should always be the first imaging modality. Sonography is most useful in the diagnosis of fluid collections in a joint or in the extra-articular soft tissues but is not useful for evaluating presence of osseous infection. CT scan can be a useful method to detect early osseous erosion and to document the presence of sequestrum, foreign body, or gas formation but
