Which imaging modality is most appropriate to assess the extent of infection in suspected osteomyelitis?

The key idea is to map how far an infection has spread within bone and into surrounding tissues. MRI with gadolinium contrast is the most informative tool for this because it vividly shows bone marrow edema and the full extent of infection in the marrow, cortex, and adjacent soft tissues. The contrast helps distinguish active infectious tissue from non-infected edema and clearly reveals abscesses, phlegmon, and any joint involvement, which is essential for planning treatment. X-ray often misses early osteomyelitis and only shows changes after the disease has progressed. CT provides excellent detail of cortical bone and can identify sequestra, but it doesn’t image marrow edema or soft-tissue extension as effectively as MRI. Ultrasound is limited to superficial soft tissues and cannot assess bone marrow involvement, so it cannot capture the true extent of osteomyelitic infection. Hence, MRI with contrast offers the most comprehensive view of infection spread, guiding management decisions most effectively.
