Overview
CT scan can demonstrate osseous and soft-tissue abnormalities and is ideal for detecting gas in soft tissues. Bones like the sternum, vertebrae, pelvic bones, and calcaneus are far better imaged with a CT scan than with plain radiographs.
CT scan
CT scan is usually more readily available for establishing the diagnosis especially in emergencies.[1] In selected children who cannot remain still or tolerate sedation, CT is a valuable imaging modality. CT scan findings may include the following:
- Overlying soft-tissue swelling, periosteal reaction, medullary low-attenuation areas or trabecular coarsening, and focal cortical erosions.
* osseous and soft-tissue abnormalities and is ideal for detecting gas in soft tissues.
Bones like the sternum, vertebrae, pelvic bones, and calcaneus are far better imaged with a CT scan than with plain radiographs.
CT is most commonly used to detect and to define areas of possible infection in bones with complex anatomy that is difficult to visualize on plain radiographs and bone scans.[2] - The following imaging series demonstrate little infectious nidus of the left femoral neck, synovitis, soft tissue mass (abscess), sequestrum and periosteal reaction in a 4 years old boy with acute hematogenous osteomyelitis of left femur.
