摘　　要：目的：探讨CT能谱成像（gemstone spectral imaging,GSI）定量分析对臭氧微创治疗腰椎间盘突出症（lumbar disc herniation,LDH）疗效评估的价值。方法：回顾性分析38例单纯LDH患者的临床及影像资料,患者均行臭氧微创治疗,于术前及术后3-4个月行突出椎间盘GSI扫描。按照改良MacNab疗效评定标准分为显效组、有效组与无效组。多组突出椎间盘样本内水含量采用单因素方差分析,两两比较采用LSD-t检验;突出椎间盘平均水含量与3-4个月后椎间盘突出块回缩程度采用Spearman相关性检验进行分析。结果：LDH患者中,突出椎间盘平均水含量（1 058.85±0.47）g/cm3与术后椎间盘突出块的回缩程度（14.88±15.26）mm2呈正相关（P〈0.05）。显效组、有效组椎间盘突出块含水量与无效组之间差异具有统计学意义,显效组与有效组之间差异无统计学意义。结论：治疗前突出椎间盘平均水含量与治疗后最大突出椎间盘层面突出块的面积萎缩程度具有一定相关性;显效组、有效组椎间盘突出块含水量均高于无效组,可为临床疗效术前评估提供参考。Objective： To investigate the CT gemstone spectral imaging （GSI） quantitative analysis in assessment of the value of the ozone in treatment of lumbar disk herniation. Methods： 38 patients were diagnosed purely lumbar disk herniation. Treating by ozone, all patients were performed by GSI before arid three to four months after operation. According to the improved MacNab criteria, patients were divided into markedly effective group, effective group and invalid group. The analysis of multiple groups of the water content in intervertebral disk use independent samples t-test. The analysis of water content in intervertebral disk and 3 to 4 months after the intervertebral disk block retraction used Spearman test analysis of measurement data. Results： The mean water content in intervertebral disk was （1058.85±0. 47）g/cm^3 and the mean retraction of the intervertebral disk block was （14.88± 15.26）mm^2 after operation. And they had a positive correlation. Between markedly effective, effective group and invalid group, intervertebral disk block water content had a statistic difference, there was no significant difference between effective group and invalid group. Conclusion： Before and after treatment,the water content and retraction of the largest level of intervertebral disk herniation blocks has a certain correlation. The intervertebral disk block water content of markedly effective, effective group are higher than the invalid group. It provides the reference for clinical preoperative assessment of curative effect.
