摘　　要：目的研究MRI检查中马尾神经沉降(NRSS)情况与腰椎管狭窄症的相关性。方法收集2018年1月至2021年6月80例腰椎管狭窄症患者临床资料,患者均接受腰椎MRI检查,记录NRSS阳性征发生情况,比较不同征象患者基本资料、临床征象和腰椎管狭窄分型,分析影响NRSS阳性征的相关因素。结果80例患者中,NRSS阳性者64例,阴性者16例,阳性率80.00%。NRSS阳性组与NRSS阴性组患者ODI评分、狭窄分型、狭窄节段、狭窄椎管硬膜囊面积及狭窄椎管前后径比较,差异均有统计学意义(P<0.05)。NRSS阳性患者中,a型26例,b型22例,c型16例,不同亚型患者ODI评分、狭窄分型、狭窄椎管硬膜囊面积及狭窄椎管前后径比较,差异均有统计学意义(P<0.05)。对可能影响NRSS阳性征的相关因素赋值,带入进行Logistic多因素分析显示,ODI评分、狭窄分型及狭窄椎管前后径与NRSS阳性征密切相关(P<0.05)。结论MRI检查中NRSS阳性征有助于腰椎狭窄分型诊断和腰椎管狭窄程度判断,值得临床推广应用。Objective To study the correlation between nerve root sedimentation sign(NRSS)and lumbar spinal stenosis(LSS)in magnetic resonance imaging(MRI)examination.Methods Clinical data of 80 LSS patients from January 2018 to June 2021 were collected.All patients were managed by lumbar spine MRI examinations to record the positive rate.the aim was to compare the classifications of LSS in patients with different signs and analyze the influencing factors of positive NRSS.Results Among the 80 patients,the positive rate was 80.00%(64/80),and 20%(16/80),respectively.The difference was statistically significant in the Oswestry Disability Index(ODI)scores,stenosis classification,swing-segment stenosis,dural cross-sectional area of canal,spinal canal diameter between the two groups(P<0.05).The NRSS-positive patients of different subtypes had significant differences in ODI scores,stenosis classification,dural cross-sectional area of canal,spinal canal diameter(P<0.05).Logistic multivariate analysis showed that ODI score,stenosis classification and anteroposterior diameter of the spinal canal were closely related to positive NRSS(P<0.05).Conclusion In MRI examination,the positive NRSS is helpful for diagnosing the classifications and degree of LSS,worthy of clinical application.
