| 目的探讨多发骨质疏松性椎体骨折中，急性或亚急性椎体骨折的MRI表现。方法回顾性 分析74例经我院诊治的多发骨质疏松性椎体骨折的临床资料与MR图像，在MR图像上，把骨折椎 体按形态分为5型：正常，楔形变、双凹变形、单凹变形和挤压变形（即椎体后缘压缩骨折）；按椎体高 度压缩严重程度分为4度：正常，轻度、中度和重度；根据急性或亚急性骨折椎体的分布情况分为：单 发骨折，多发连续骨折和多发不连续骨折。MR图像评价由两位有多年诊断经验的骨骼肌肉系统放 射医生完成，当有异议时，通过协商达成一致。应用Fisher'精确概率法进行统计学分析。结果在 74例患者中，共有592个椎体纳入研究，骨折椎体有280个，占47.3%.。其中101个椎体为急性或亚 急性骨折，占椎体骨折的36. 1%。椎体形态改变：楔形变23个（22. 8% )，双凹变形60个（59.4% )， 单凹变形16个（15.8% )，挤压变形2个（2. 0% )。椎体高度压缩程度：轻度压缩20个（19.8%.)，中 度压缩44个（43.6%.)，重度压缩37个（36.6%.)。急性或亚急性骨折椎体的分布：单发54例 (73.0% )，多发连续11例（14. 9% )，多发不连续9例（12.2% )。结论在多发骨质疏松性椎体骨折 中，MRI特点有助于急性或亚急性椎体骨折的诊断。 |

| To investigatethe MR miaging characteristic of the acute or subacute vertebral fracture in multi-level osteoporotic vertebral rraclures. Methods Seventy-four patients with multi-level osteoporotic vertebral fractures who underweiU MRI were retrospectively analyzed. On MRI，according to the morphology， the vertebrae were classified as five types ： normal，wedge， biconcave， uniconcave and crush. According to the severity of vertebral height reduction， the vertebrae delomiity was classified as nomial， mild ^ moderate and severe. The extent of the acute or subacute vertebral fracture was classified as single fracture^ multiple continuous fractures o^ multiple discontinuous fractures. AU MRI data were analyzed by Lwo senior musculoskeletal radiologists in consensus. The Fisher ’ s test was used for statistical analyses. Result 592 vertebras of the 74 patients were reviewed，280 ( 47.3%' ) of ihem were fracture. and 101 (36. 1 % ) were acute or subacute vertebral faclures. Among the 101 vertebral fractures，23( 22. 8% ) were wedge defomiity，60( 59. 4% ) were biconcave， 16( 15. 8% ) were uniconcave，2 were crush ( 2. 0% ). 20 vertebrae ( 19. 8% ) were mildly defomiity， 44 vertebrae ( 43. 6% ) were moderate defomiity， and 37 vertebra ( 36. 6% ) were severe defomiity. 54 ( 73. 0% ) patients were present as single fracture， 11 (14. 9%■ ) were multiple con tinuous fracture and 9 ( 12. 2%' ) were multiple discontinuous fracture. |
