目的 分析原发性骨质疏松椎体 压缩性骨折的X线、MRI影像学特点。方 法 以2010年6月至2016年1月经影像学、 临床或病理证实的100例椎体压缩性骨折 患者为研究对象，其中原发性骨质疏松椎 体压缩性骨折56例，设为观察组，均接 受X线片、MRI检查，转移瘤继发性椎体 压缩性骨折42例，设为对照组，均行MRI 检查，X线检查者15例，对两组骨折患者X 线、MRI影像特点观察并比较。结果 X线 片图像特点：观察组检出椎体骨折70个， 椎体形态方面以凹陷形为主，占65.71%； 椎体骨密度多降低，占95.71%；椎管变形 占11.43%；累及终板占31.43%；对照组 检出椎体22个，椎体形态方面以楔形压 缩为主，占54.55%；其次是凹陷形，占 31.82%；溶骨型占81.82%；椎管狭窄占 18.18%；累及终板占40.91%。MRI图像特 点：观察组显示椎体后缘上角或下角后翘 占97.14%；T1WI序列显示局限性低信号27 个，T2WI脂肪抑制序列显示高信号41个； 对照组显示圆隆状椎体后缘占96.15%；不 规则结节状椎体旁软组织肿块38个；骨折 病灶T1WI显示弥漫性低信号43个；T2WI脂 肪抑制序列显示高信号48个；增强扫描显 示明显强化。结论 X线、MRI在原发性骨 质疏松与转移瘤继发性椎体压缩性骨折鉴 别诊断中有重要价值。

Objective To analyze the characteristics of X-ray and MRI imaging features of primary osteoporotic vertebral compression fractures. Methods One hundred patients with vertebral compression fracture in our hospital between June 2010 to January 2016 were studied and 56 cases with the primary osteoporotic vertebral compression fractures were chosen as the observation group which received X-ray, MRI. Forty-two cases with vertebral compression fracture secondary to metastatic tumor were chosen as the control group which all underwent MRI examination but 15 cases underwent X-ray examination. The X-ray, MRI features of the fracture between the two groups were observed and compared. Results X-ray image characteristics: observation group detected 70 cases with vertebral fracture, the vertebral body were mainly depressed shape and it account for 65.71%, the vertebral bone mineral density decreased, accounting for 95.71%, spinal deformation for 11.43%, the fracture involving the endplate for 31.43%, control group detected 22 cases with vertebral fracture and vertebral morphology were wedge compression mainly, accounting for 54.55%, secondly is concave, 31.82%, the osteolytic type for 81.82%, spinal stenosis for 18.18%, with the involving endplate 40.91%. MRI features: the observation group showed vertebral angle or corner after alice was 97.14%, T1WI showed 27 localized low signal, T2WI fat suppression sequences showed high signal in 41 cases, control group showed 96.15% of the cases with dome shaped vertebral body, 38 cases with irregular nodular paravertebral soft tissue mass. T1WI showed fracture lesions diffuse low signal in 43 cases. T2WI fat suppression sequences showed 48 cases high signal, the enhanced scanning showed obvious enhancement. Conclusion X-ray and MRI have important value in the differential diagnosis of primary osteoporosis and vertebral compression fractures secondary to metastatic tumor.
