摘　　要：目的 研究核磁共振成像(MRI)与磁共振弥散张量成像(DTI)对无骨折脱位的急性颈髓损伤的诊断价值。方法回顾性分析无骨折脱位型急性颈髓损伤患者70例的临床资料,均采用X射线及CT检查,未检出骨折,随后采用MRI与DTI检查,证实患者有颈髓损伤,测量患者表观弥散系数(ADC)及各向异性分数(FA),记录日本骨科协会评估治疗JOA评分,分析表观弥散系数(ADC)及各向异性分数(FA)值与JOA评分的相关性。结果 70例无骨折脱位的急性颈髓损伤患者中,有12例Ⅰ级患者,有21例Ⅱ级患者,有22例Ⅲ级患者,有15例Ⅳ级患者;各级患者信号特征不同;JOA各分级患者ADC及FA值比较,差异有统计学意义(P<0.05);经Pearson相关性分析,ADC值与JOA评分无明显相关性(r=0.197,P=0.058);FA值与JOA评分呈正相关(r=0.869,P=0.000)。结论 DTI可反馈无骨折脱位型颈髓损伤的病理过程,通过FA指标评估患者病情严重程度,并为判断预后提供依据。Objective To investigate the diagnostic value of magnetic resonance imaging(MRI)and magnetic resonance diffusion tensor imaging(DTI)in acute cervical spinal cord injury without fracture and dislocation.Methods Retrospective analysis treated the patients with acute cervical cord injury without fracture dislocation of the clinical data of 70 cases,adopt the X-ray and CT examination,fracture detection,then using MRI and DTI examination,confirmed that patients with cervical spinal injury,patients with measuring apparent diffusion coefficient(ADC)and anisotropic scores(FA),The Japanese Orthopaedic Association evaluation treatment(JOA)score was recorded to analyze the correlation between apparent dispersion coefficient(ADC)and anisotropy score(FA)and JOA score.Results There were 12 grade ⅰ patients,21 grade ⅱ patients,22 grade ⅲ patients and 15 grade ⅳ patients in 70 patients with acute cervical spinal cord injury without fracture and dislocation.Different signal characteristics of patients at different levels;There were statistically significant differences in ADC and FA values among JOA grades(P<0.05).Pearson correlation analysis showed that ADC value had no significant correlation with JOA score(r=0.197,P=0.058).FA was positively correlated with JOA score(r=0.869,P=0.000).Conclusion DTI can feedback the pathological process of cervical spinal cord injury without fracture and dislocation,evaluate the severity of patients’ disease by FA index,and provide a basis for the judgment of prognosis.
