摘　　要：目的观察测量腰椎间孔斜位MRI成像基础上相关参数变化,并探讨其在椎间孔狭窄中的应用价值。方法随机选择2016年7月—2018年12月本院临床诊断L4/5腰椎管狭窄症并椎间孔狭窄者共68例为研究对象,对106个L4/5椎间孔狭窄MRI资料进行研究;依椎间孔MRI成像方式分为两组:A组(对照组)腰椎矢状位成像组;B组(观察组)腰椎间孔约45°斜位成像组;分别将其在正中矢状位及斜位像上测量L4/5节段椎间孔的最大高度、最大宽度、面积与根突距离等;对比分析两组相应椎间孔参数差异并探讨在椎间孔狭窄中的诊断价值。结果正中矢状位及斜位成像技术下的椎间孔最大高度差异具有统计学意义(P<0.05);矢状位及斜位成像技术下的椎间孔最大宽度差异无统计学意义(P>0.05);矢状位及斜位成像技术下的神经根与相应椎间孔面积之比,两组间差异具有统计学意义(P<0.01);两组间106孔中根突距测量有显著性差异(P<0.05)。结论腰椎椎间孔斜位MRI成像在反应椎间孔狭窄中可能更直观可靠,对腰椎间孔狭窄的术前准确判断及手术方式有一定的指导意义。Objective To measure the parametric changes of intervertebral foramen based on the angled MRI and explore its clinical application value in treating intervertebral foramen stenosis.Methods From July 2016 to December 2018,the 68 cases of patients diagnosed as L4/5 lumbar spinal stenosis combined with intervertebral foramen stenosis were enrolled as study subjects,the MRI data of 106 L4/5 intervertebral foramen stenosis were studied.According to the imaging modes of MRI the patients were divided into two groups including group A(control group)which was sagittal MRI imaging group,group B(observation group)which was about 45°oblique imaging group of lumbar intervertebral foramen.The maximum height,maximum width,area,and the distance between root processus of the L4/5 intervertebral foramen were measured at sagittal position and oblique position.We analyzed the parameters of the two groups and its clinical significance in the diagnosis of intervertebral foramen stenosis.Results There was a statistical significance between the sagittal MRI imaging and the angled MRI imaging in the maximum height of intervertebral foramen(P<0.05).There was no significant difference in the maximum width of intervertebral foramen between the two groups(P>0.05).There was a statistical significance between the sagittal MRI group and the angled MRI group in the ratio of nerve root to intervertebral foramen area(P<0.01).There was a statistical significance between the sagittal MRI group and the angled MRI group in the length of nerve root to processus articularis(P<0.05).Conclusions Oblique MRI imaging could more directly reflect the lumbar intervertebral foramen stenosis.It has a certain guide significance in accurate preoperative judgement and decision of modus operandi for intervertebral foramen stenosis.
