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.
对44例患者进行了47次足部磁共振成像（MRI）检查，以评估MRI对足部炎症和疑似骨髓炎患者临床管理的影响。29例患者患有糖尿病。34例患者进行了骨活检或骨培养，大多数患者都有常规X线片和骨扫描检查结果可供比较。磁共振成像显示对骨感染的识别可靠，敏感性为100%，特异性为95%。普通X线片不准确，正如预期的那样，骨扫描高度敏感（90%）但不具特异性（33%）。MRI的高准确性有助于更好地识别骨髓炎患者，从而改进对潜在手术候选者的筛选。
