目的 探讨椎体压缩性骨折伴出 血患者MRI、CT影像学诊断价值。方法 回 顾性分析2009年1月至2014年我院骨伤科 收治经手术病理证实的32例椎体压缩性骨 折伴出血患者的临床资料，对所有病例患 者CT及MRI影像学特点进行分析并比较， 同时评估两种诊断方法的应用价值。结果 32例研究对象中，28例为单个椎体病变， 3例为双节椎体病变，1例为三节椎骨折， 病变部位：胸椎18例，腰椎14例。MRI影 像学特点显示椎体形态：楔形16例，倒楔 形0例，凹陷形14例，扁平形2例；T1WI低 信号10例，T2WI高信号8例，DWI低信号12 例，DWI高信号2例；后缘膨隆3例，成角 29例；椎弓根破坏0例，T1WI低信号1例； 结节肿块0例，环形增厚11例。CT表现为 椎体前缘、侧缘可见透亮线。17例局部骨 皮质断裂不连，7例椎体前缘双边改变， 12例椎体中前柱骨质致密、紊乱，3例经 CT判断为外伤性压缩性骨折，同时可见 椎体前缘骨皮质内细小裂隙，仅1例表现 为椎体前缘局部骨密度增高与椎体相续。 结论 通过对椎体压缩性骨折伴出血患者 MRI、CT影像学特点进行分析，提示两者 对椎体压缩性骨折伴出血患者均具有较高 的诊断价值。

Objective To investigate the diagnostic value of MRI and CT in the patients of vertebral compression fracture complicated with hemorrhage. Methods The clinical data of 32 patients with pathologically confirmed vertebral compression fracture with hemorrhage who were treated in our hospital between January 2009 and 2014 were analyzed retrospectively. The CT and MRI features of all cases were analyzed and compared. The application value of the two diagnostic methods was evaluated. Results Among 32 subjects, there were 28 cases with single vertebral lesions, 3 cases with double vertebral lesions and 1 case with triarticular vertebral lesions, 18 cases with lesions in thoracic vertebra and 14 cases in lumbar vertebrae. MRI findings showed the shapes of vertebral body were as following: wedge-shaped in 16, inverted wedge-shaped in 0 case, concave shape in 14 cases and flat-shaped in 2 cases. There was low signal on T1WI in 10 cases, high signal on T2WI in 8 cases, low signal on DWI in 12 cases, and high signal on DWI in 2 cases. There was trailing edge distension in 3 cases, angulation in 29 cases and pedicle destruction in 0 case, low signal on T1WI in 1 cases, nodular masses in 0 case and ring thickening in 11 cases. CT showed anterior and lateral vertebral margin with lucency transparent lines. There were 17 cases with local cortical bone fracture nonunion, 7 cases with vertebral bilateral alterations and 12 cases with compact vertebral anterior column bone density and disorder. Three cases with traumatic compression fractures were diagnosed by CT. Besides, there was anterior vertebral bone cortex with small cracks, and only 1 case showed local vertebral bone density increasing and vertebral body connection. Conclusion Through the analysis of MRI and CT imaging features of patients with vertebral compression fracture complicated with hemorrhage, it indicates that both of them is of high value in the diagnosis of the disease.
