Between January 1985 and December 1988 41 patients with clinically suspected osteomyelitis were examined by MRI. All cases were proved either by surgery or by clinical follow-up. Evidence of osteomyelitis on MRI consisted of abnormalities of the bone marrow with decreased signal intensity on T1-weighted images and increased signal intensity on T2-weighted images. Other abnormalities such as degeneration of the intervertebral disc, fatty degeneration of the muscles and thickening of tendon sheaths with fluid were also seen on the same images. The sensitivity of the MRI for the diagnosis of osteomyelitis was 100%, the specificity was 86% and the accuracy 96%. We conclude that MRI is a reliable method in diagnosing osteomyelitis because of its high sensitivity and high specificity.
1985年1月至1988年12月期间，对41例临床怀疑患有骨髓炎的患者进行了磁共振成像（MRI）检查。所有病例均通过手术或临床随访得以证实。MRI上骨髓炎的表现为骨髓异常，在T1加权图像上信号强度降低，在T2加权图像上信号强度增加。在同一图像上还可见到其他异常，如椎间盘退变、肌肉脂肪变性以及腱鞘增厚并伴有积液。MRI诊断骨髓炎的敏感性为100%，特异性为86%，准确性为96%。我们得出结论，由于MRI具有高敏感性和高特异性，它是诊断骨髓炎的可靠方法。
