OBJECTIVE
Identify key magnetic resonance imaging (MRI) features that have a significant correlation with osteomyelitis of pressure ulcers in spinal injury patients.
DESIGN
Retrospective review study.
PARTICIPANTS
Adult patients admitted to the National Spinal Injuries Centre with spinal cord injury (SCI) and signs of pressure ulceration investigated with MRI.
METHODS
Analysis of MRI examinations and clinical records collected over a 4-year period. Images were independently assessed by 2 experienced radiologists for osteomyelitis based on assigned predictive indicators including cortical bone erosion, soft tissue edema, deep collections, heterotopic new bone, hip effusion, and abnormal signal change of the marrow.
RESULTS
Thirty-seven patients underwent 41 MRI scans. The prevalence of osteomyelitis was highly correlated with cortical bone erosion (r = 0.84) and abnormal bone marrow changes on T1-weighted images (r = 0.82).
目的
确定与脊髓损伤患者压疮性骨髓炎具有显著相关性的关键磁共振成像（MRI）特征。
设计
回顾性研究。
参与者
入住国家脊髓损伤中心且患有脊髓损伤（SCI）并有压疮迹象的成年患者，接受了MRI检查。
方法
分析4年期间收集的MRI检查结果和临床记录。由2名经验丰富的放射科医生根据指定的预测指标，包括皮质骨侵蚀、软组织水肿、深部积液、异位新骨、髋关节积液和骨髓异常信号变化，对图像进行独立评估，以判断是否存在骨髓炎。
结果
37例患者接受了41次MRI扫描。骨髓炎的患病率与皮质骨侵蚀（r = 0.84）和T1加权图像上的骨髓异常变化（r = 0.82）高度相关。
