Thirty-one patients (29 males and two females, 13-87 years of age (mean, 46.7 years] with acute spinal cord injury were studied by MR (magnetic resonance) imaging and the results were correlated with neurological findings. Magnetic resonance images were obtained with a 0.5 T superconductive MR scanner (Phillips Gyroscan S5). Initial imaging was performed within 24 hours after trauma in 13 patients, 1-7 days in 13 patients and 7-14 days in five patients. Twenty-six patients underwent follow-up examinations with MR imaging. Cord abnormalities including cord compression (23 patients), cord swelling (seven patients), and abnormal signal intensities on either T1 or T2-weighted images (26 patients) were observed on initial examination. Multivariate analysis showed that cord compression and abnormal intensities on T1-weighted images were important prognostic indicators. Hyperintensity on T2-weighted images was non-specific but correlated well with clinical recovery. Magnetic resonance imaging is useful in predicting the prognosis and for planning treatment following spinal cord injuries.
对31例急性脊髓损伤患者（29例男性，2例女性，年龄13 - 87岁，平均46.7岁）进行了磁共振（MR）成像研究，并将结果与神经学检查结果进行了关联分析。使用0.5T超导MR扫描仪（飞利浦Gyroscan S5）获取磁共振图像。13例患者在创伤后24小时内进行了首次成像，13例患者在1 - 7天内进行了成像，5例患者在7 - 14天内进行了成像。26例患者接受了MR成像随访检查。初次检查时观察到脊髓异常，包括脊髓受压（23例患者）、脊髓肿胀（7例患者）以及T1或T2加权图像上的异常信号强度（26例患者）。多变量分析表明，脊髓受压和T1加权图像上的异常强度是重要的预后指标。T2加权图像上的高信号强度不具有特异性，但与临床恢复密切相关。磁共振成像有助于预测脊髓损伤后的预后并为治疗方案的制定提供依据。
