| 中文摘要: |
| 目的研究MRI及X线平片在糖尿病性足部骨髓炎诊断中的价值。方法对50例疑有足部骨髓炎的糖尿病患者行MRI及X线平片检查。结果50例患者中37例MRI诊断为骨髓炎,其中19例X线平片亦可见骨髓炎征象。32/37例行外科手术治疗,手术获得62个骨标本,经组织学证实为骨髓炎的46个骨。MRI敏感性99%,特异性81%,准确性94%.结论MRI可显示细微的解剖结构,诊断糖尿病引起的足部骨髓炎较X线平片具有较高的敏感性、特异性及准确性。本组切除MRI诊断为骨髓炎的病变骨,临床上均得到了治愈结果。 |

| Purpose To assesss the role of magnetic resonance imaging (MRI)in diagnosing osteomyelitis in diabetic foot infections.Methods 50 diabetic patients with clinical suspicion of osteomyelitis,nonhealing foot ulcer,or soft tissue infection of the foot were examined prospectinely by MRI and plain radiographs.Results Pathological confirmation of diagnosis was obtained in 62 bones from 32 patients.The sensitivity,specificity and accuracy of MRI were 99%,81% and 94%.Conclusion MRI had improved sensitivity,specificity and accuracy compared with plain radiographs in the diagnosis of osteomyelitis in diabetic foot infections.Complete resection of infected bone detected by MRI led to would healing in all cases.MRI provides greater anatomial detail and is therefore usufull in preoperative planning. |
