摘要
目的:分析基于磁共振T_(2)加权相(T_(2)WI)矢状位-轴位MRI指标评估退变性腰椎不稳(DLI)腰骶角、韧带厚度值及小关节积液宽度差异。方法:选择医院收治的98例DLI患者,将其纳入观察组,同期选择医院查体中心的40名健康体检者纳入对照组。所有受检者均采用磁共振T_2WI矢状位-轴位MRI测量腰骶角、韧带厚度值及小关节积液宽度水平,分析磁共振T_(2)WI矢状位-轴位MRI指标与DLI的相关性,采用受试者工作特征(ROC)曲线分析磁共振T_2WI矢状位-轴位MRI指标评估DLI的价值。结果:观察组患者腰骶角、黄韧带厚度水平明显高于对照组,差异有统计学意义(t=2.099,t=0.855;P<0.05);两组腰椎间盘退变分级、小关节退变分级比例差异有统计学意义(x^(2)=8.349,x^(2)=33.622;P<0.05)。观察组患者DLI与腰骶角、小关节积液量宽度、腰椎间盘退变分级呈正相关,与小关节退变分级呈负相关(r=0.185,r=0.316,r=0.256,r=-0.617;P<0.05);腰骶角、小关节积液量宽度、腰椎间盘退变分级和小关节退变分级诊断DLI的ROC曲线下面积(AUC)分别为0.784、0.796、0.839和0.815。结论:DLI与腰骶角、小关节积液量宽度、腰椎间盘退变分级及小关节退变分级存在明显相关性,其中腰骶角、小关节积液退变分级和腰椎间盘退变分级诊断DLI具有一定价值。
Objective:To analyze the differences of lumbosacral angle,ligament thickness and the widths of facet joint effusion of degenerative lumbar instability(DLI)based on sagittal-axial magnetic resonance imaging(MRI)images of MR T2 weighted imaging(T2WI).Methods:98 patients with degenerative lumbar instability(DLI)were selected and they were included in the observation group,and 40 healthy persons who underwent physical examination in the physical examination center of hospital were divided into the control group.All subjects underwent the detection of sagittal-axial MRI images of MR T2WI for lumbosacral angle,ligament thickness and width level of facet joint effusion.And then the correlation between sagittal-axial MRI image indicators of MR T2WI and DLI was analyzed.The receiver operating characteristics(ROC)curve was adopted to analyze the value of sagittal-axial MRI image indicators of MR T2WI in assessing DLI.Results:The lumbosacral angle and the thickness of yellow ligament of observation group were significantly higher than those of control group(t=2.099,t=0.855,P<0.05).The differences of the ratios of the grading of lumbar disc degeneration and facet joint degeneration between the two groups were statistically significant(x^(2)=8.349,x^(2)=33.622,P<0.05).In observation group,DLI was positive correlation with lumbosacral angle,the width of facet joint effusion volume and grading of lumbar disc degeneration,and was negative correlation with the grading of facet joint degeneration(r=0.185,r=0.316,r=0.256,r=-0.617,P<0.05).The area under curves(AUC)of ROC curves of lumbosacral angle,the width of facet joint effusion,the grading of lumbar disc degeneration and the grading of facet joint degeneration were0.784,0.796,0.839 and 0.815 in diagnosing DLI,respectively.Conclusion:DLI has significant correlation with lumbosacral angle,the width of facet joint effusion,the grading of lumbar disc degeneration and the grading of facet joint degeneration.Among of them,lumbosacral angle,the grading of facet joint effusion degenerat
