摘　　要：目的比较良恶性椎体骨折采用磁共振化学位移成像与扩散加权成像的诊断效果。方法选择本院2014年11月~2016年11月期间收治的良性椎体骨折28例和恶性椎体骨折20例行磁共振化学位移成像与扩散加权成像诊断,比较鉴别良恶性椎体骨折的准确性、敏感性和特异性。结果恶性椎体骨折诊断化学位移成像反相位信号敏感性93.3%,扩散加权成像诊断敏感性86.76%;化学位移成像存在差异显著性,P<0.05。结论在良恶性椎体骨折鉴别中诊断中采用磁共振化学位移成像定量分析具有更高的价值,值得推广。Objective To compare the effect and diagnosis of benign and malignant vertebral fractures using magnetic resonance diffusion weighted imaging of chemical shift imaging. Methods Twenty-eight patients with benign vertebral fractures and 20 cases of malignant vertebral fractures were selected from November 2014 to November 2016.MR imaging and diffusion weighted imaging were used to diagnose the accuracy and sensitivity of benign and malignant vertebral fractures,sexuality and specificity. Results Malignant vertebral fracture diagnosis of chemical displacement imaging anti-phase signal sensitivity of 93.3%,diffusion-weighted imaging diagnostic sensitivity of 86.76%, there was significant difference,P 〈0.05. Conclusion Quantitative analysis of magnetic resonance chemical displacement imaging in the diagnosis of benign and malignant vertebral fractures is of great value and worthy of promotion.
