目的 探讨腰腿痛患者中腰椎间盘磁共振成像(MRI)局限性高信号区(HIZ)的分布特点,并分析发生HIZ的相关因素.方法 选取2009年6月至2010年8月因腰腿痛行腰椎MRI检查的患者628例.分析HIZ在年龄、椎间盘节段和椎间盘退变中的分布特点及其相关因素.结果 628例患者3140个椎间盘中,172例(27.39％,172/628 )206个椎间盘(6.56％,206/3140)存在HIZ.其中男性患者和女性患者HIZ的发生率分别为26.38％(86/326)和28.48％( 86/302),差异无统计学意义(P=0.556).40～49岁是HIZ发生率最高的年龄段[40.22％(72/179)].椎间盘节段存在HIZ的发生率:L1～2 0.80％(5/628)、L2～3 2.07％ (13/628)、L3～42.07％(13/628)、L4～5 14.01％(88/628)、L5～S113.85％(87/628).有和无HIZ时椎间盘退变程度≥Ⅳ级者的发生率分别为49.03％( 101/206)及23.76％(697/2934),差异有统计学意义(P＜0.01).年龄、椎间盘退变程度、椎间盘节段与HIZ均具有相关性(r=-0.040,P=0.025;r=0.217,P＜0.01；r=0.179,P＜0.01).结论 腰腿痛患者中腰椎间盘MRI发生HIZ与年龄、椎间盘节段、椎间盘退变程度之间存在相关性,椎间盘退变程度是最重要的影响因素.HIZ最常发生于L4～5和L5～S1节段,40～ 49岁是高发年龄段.

Objective To investigate the distribution of high-intensity zone (HIZ) of lumbar intervertebral disc in patients with low back and/or leg pain,and analyze its related factors.Methods Six hundred and twenty-eight patients with low back and/or leg pain were examined by MRI scan from June 2009 to August 2010.According to the diagnostic criteria of HIZ,the features of distribution of HIZ on age,segment and degree of intervertebral disc degeneration were analyzed retrospectively.Results Among 3140 intervertebral discs of the 628 patients,172 cases (27.39％,172/628) and 206 discs (6.56％,206/3140)were involved with HIZ.There was no significant difference between men and women [26.38％(86/326)vs.28.48％(86/302)] (P=0.556).HIZ occurred more often [40.22％(72/179)] in those patients between 40 and 49 years of age.The incidence of HIZ at the segments from L1-2,L2-3,L3-4,L4-5,L5-S1 was 0.80％(5/628),2.07％(13/628),2.07％(13/628),14.01％(88/628) and 13.85％(87/628) respectively.In cases with and without HIZ,the incidence of intervertebral disc degeneration up to grade V was 49.03％(101/206) and 23.76％(697/2934) respectively (P ＜ 0.01 ).HIZ was correlated with age,degree of intervertebral disc degeneration and disc segment (r =-0.040,P=0.025 ;r =0.217,P＜ 0.01 ;r =0.179,P＜ 0.01 ).Conclusions HIZ is correlated with age,degree of intervertebral disc degeneration and disc segment.Intervertebral disc degeneration plays the most important role in the occurence of HIZ.HIZ_mainly occur in L4-5 and L5-S1 segment and in those between 40 and 49 years of age.
