Clinical impact of magnetic resonance imaging in foot osteomyelitis

ND Nigro, WS Bartynski, SJ Grossman and S Kruljac
Podiatry Hospital of Pittsburgh, PA.

The impact of magnetic resonance imaging (MRI) on the clinical management of patients with foot inflammation and suspected osteomyelitis was evaluated in 44 patients with 47 foot MRI exams. Twenty-nine patients were diabetic. Bone biopsy or bone culture was obtained in 34 patients, and routine radiographs and bone scan studies were available in most patients for comparison. Magnetic resonance imaging showed reliable identification of bone infection with a sensitivity of 100% and specificity of 95%. Plain radiographs were inaccurate and, as expected, bone scans were highly sensitive (90%) but not specific (33%). The high accuracy of MRI allowed for better identification of patients with osteomyelitis and, therefore, improved targeting of potential operative candidates.
