【摘要】 目的评价MRI脂肪抑制成像在老年骨质疏松性椎体骨折椎体后凸成形术(percutaneous kyphoplasty,PKP)治疗中的应用价值。方法自2008-02—2013-08对88例老年骨质疏松性椎体骨折行PKP治疗,根据入院前X线片及CT检查,分为单椎体组(56例)和多椎体组(32例)。术前行MRI脂肪抑制成像检查确定骨折椎体,比较2组行MRI检查前后的诊断符合率。结果单椎体组和多椎体组诊断符合率分别为83.9%和68.8%,差异有统计学意义(P<0.05)。结论传统的X线片及CT检查对于骨质疏松性多发椎体骨折容易漏诊,MRI脂肪抑制成像能够提高骨质疏松性椎体骨折的诊断率。更多还原

【Abstract】 Objective To evaluate the value of of MRI fat-suppression image for osteoporotic vertebral fracture treated with percutaneous kyphoplasty. Methods From Feb. 2008 to Aug. 2013, eighty-eight patients with osteoporotic vertebral fracture were treated with percutaneous kyphoplasty. The patients were divided into two goups: single-level fracture group and multiple-level fracture, according to X-ray and CT scan examination before admission to hospital. The involved vertebrae were determined according to MRI fat-suppression examination. The diagnostic coincidence rates were compared in two groups according to MRI fat-suppression examination. Results The diagnostic coincidence rates were 83.9% in single-level group and 68.8% in multiple-level group respectively. There was significantly difference in single-level group compared with multiple-level group(P <0.05). Conclusion MRI fat-suppression can significantly improve diagnostic coincidence rate of osteoporotic vertebral fracture compared with X-ray and CT scan examination.更多还原
