摘要: 本次研究目的是探讨磁共振成像(MRI)椎旁肌脂肪浸润占比、横截面积、腰椎前凸角诊断腰椎不稳的应用价值。选取退变性腰椎不稳患者87例作为观察组,同时选取体检健康者50例作为对照组,两组均给予MRI检查,比较两组椎旁肌脂肪浸润占比、横截面积、腰椎前凸角差异。结果显示观察组多裂肌横截面积、竖脊肌脂肪浸润占比明显低于对照组(P<0.05);观察组多裂肌脂肪浸润占比和腰椎前凸角明显高于对照组(P<0.05);观察组不同节段不稳、不同Frymoyer分型患者MRI各参数比较,差异均有统计学意义(P<0.05);多裂肌横截面积及脂肪浸润占比、竖脊肌脂肪浸润占比、腰椎前凸角诊断腰椎多节段不稳的ROC曲线下面积均较大。本次研究证实MRI椎旁肌脂肪浸润占比、横截面积、腰椎前凸角诊断腰椎不稳有一定应用价值,其中腰椎前凸角诊断价值高。

Abstract: The purpose of this study was to investigate the value of magnetic resonance imaging (MRI) in the diagnosis of lumbar instability, including the proportion of paravertebral muscle fat infiltration, cross-sectional area and lumbar lordosis. Eighty-seven patients with degenerative lumbar instability were selected as observation group, and 50 healthy subjects were selected as the control group. MRI examination was performed in both groups, the proportion, cross-sectional area and lumbar lordosis of paravertebral muscle fat infiltration were compared between the two groups. The results show that the cross-sectional area of the multifidus muscle and the percentage of fat infiltration in erector spinae in the observation group were significantly lower than those in the control group (P<0.05). The percentage of fat infiltration and lumbar lordosis in the observation group were significantly higher than those in the control group (P<0.05). The MRI parameters of patients with different segmental instability and frymoyer classification in the observation group were statistically significant (P<0.05). The area under the ROC curve of the cross-sectional area and the proportion of fat infiltration of the multifidus muscle in diagnosing multisegment instability were big enough (P<0.05), as well as the fat infiltration proportion in erector spinae and lumbar lordosis. This study confirmed that proportion of fat infiltration and cross-sectional area in paravertebral muscles on MRI have certain application value in the diagnosis of lumbar instability, as well as the lumbar lordosis, which has the highest diagnosis value.
