Overview
The role of MRI in the diagnosis of septic arthritis has been increasing in recent years in an effort to detect this entity earlier.[1] Findings are usually evident within 24 hours following the onset of infection and include: synovial enhancement, perisynovial edema and joint effusion. Signal abnormalities in the bone marrow can indicate a concomitant osteomyelitis.[2] The sensitivity and specificity of MRI for the detection of septic arthritis has been reported to be 100% and 77% respectively.
