1.5T磁共振扩散加权成像在急性脊髓损伤诊断中的临床应用价值分析

Clinical application value analysis of 1.5 T diffusion weighted imaging in the diagnosis of acute spinal cord injury

研究1.5T磁共振扩散加权成像在急性脊髓损伤诊断中的临床应用价值。方法：收治急性脊髓损伤患者50例，分别对患者颈部病变部位以及周围2个脊椎距离的相对正常区域进行磁共振检测。结果：颈髓内常规MRI图像无异常信号26例，26例患者在相应的C5～6以及C5层面其ADC值的降低显著低于对照层面(P＜0.05)；MRI及DWI有异常信号患者24例，损伤部位较正常部位ADC值有明显减低(P＜0.05)。结论：1.5T磁共振扩散加权成像在急性脊髓损伤诊断中具有很高的临床应用价值。

Objective:To study the clinical application value of 1.5 T diffusion weighted imaging in the diagnosis of acute spinal cord injury.Methods:50 patients with acute spinal cord injury were selected.The cervical lesions and the relative normal distance between the around 2 vertebral distance of patients were detected by MRI.Results:The cervical cord routine MRI had no abnormal signal in 26 cases;the ADC value reduction of the corresponding C5～6 and C5 level in 26 patients were significantly lower than that of the control level(P<0.05).MRI and DWI had abnormal signal in 24 cases;the ADC value of injury site was significantly decreased than that of the normal part(P<0.05).Conclusion:1.5 T diffusion weighted imaging in the diagnosis of acute spinal cord injury has a high clinical application value.
