| 目的 观察腰部椎旁肌肉T2值诊断骨质疏松性椎体压缩性骨折(OVCF)的价值。方法 回顾性分析91例年龄>50岁腰背痛患者，其中23例临床诊断为OVCF(骨折组)，68例为腰椎间盘突出症、腰椎退行性变或终板炎等且未见椎体骨折(对照组)；比较2组临床资料及腰部T2 mapping成像所示左、右侧多裂肌和左、右侧竖脊肌T2值的差异，以临床诊断为标准，绘制受试者工作特征(ROC)曲线，计算曲线下面积(AUC)，评价根据腰部椎旁肌肉T2值及椎体陈旧性骨折诊断OVCF的效能。结果 组间患者年龄、性别及椎体陈旧性骨折比例差异均有统计学意义(P均<0.05)。骨折组双侧多裂肌和竖脊肌T2值均高于对照组(P均<0.05)。左、右侧多裂肌和左、右侧竖脊肌T2值诊断OVCF的AUC分别为0.79、0.76、0.71、0.70，与椎体陈旧性骨折(0.72)差异均无统计学意义(Z=1.197、0.811、0.112、0.245，P均>0.05)。结论 腰部椎旁肌肉T2值可用于诊断OVCF。 |

| Objective To explore the value of lumbar paravertebral muscles T2 values for diagnosing osteoporotic vertebral compression fracture (OVCF). Methods T2 mapping of 91 patients with low back pain and aged >50 years were retrospectively analyzed, including 23 cases who clinically diagnosed as OVCF (fracture group) and 68 cases of lumbar disc herniation, lumbar degeneration or endplate inflammation, etc., but without vertebral fracture (control group). Clinical data and T2 values of the left and right multifidus muscles, the left and right erector spinae were compared between groups. Based on the results of clinical diagnosis of OVCF, the receiver operating characteristic (ROC) curve was drawn, and the area under the curve (AUC) was calculated to evaluate the efficacy of T2 values of lumbar paravertebral muscles and old vertebral fractures for diagnosing OVCF. Results There were significant differences of age, gender and ratio of old vertebral fracture between groups (all P<0.05). T2 values of the bilateral multifidus and erector spinae in fracture group were all higher than those in control group (all P<0.05). AUC of T2 values of left and right multifidus, left and right erector spinae for diagnosing OVCF was 0.79, 0.76, 0.71 and 0.70, respectively, not significant different with that of old vertebral fracture (AUC=0.72, Z=1.197, 0.811, 0.112, 0.245, all P>0.05). Conclusion T2 values of lumbar paravertebral muscles could be used for diagnosing OVCF. |
