螺旋CT多平面和三维重建对肩胛骨骨折的诊断价值

Clinical value of Three-dimensional and multiplanar reconstruction of spiral CT in diaghosis of fracture of shoulder blade

目的探讨螺旋CT多平面重建及三维重建成像对肩胛骨骨折的诊断价值。方法对31例肩胛骨骨折病例行螺旋CT扫描，并行多平面重建（MPR）、三维重建（VRT）成像，对图像结果进行回顾性分析。结果31例肩胛骨骨折共发现骨折54处。MPR显示骨折54处，清楚显示骨折线及细小骨碎片，尤其是关节内碎骨块显示清楚，但不能显示骨折三维空间关系；VRT发现骨折51处，图像直观、逼真，立体感强，多方位显示骨折空间改变，但对细小无移位的骨折线显示不佳。结论螺旋CT多平面重建及三维重建相结合对肩胛骨各种类型骨折显示准确率高、立体感强，并可显示关节对应关系及周围软组织损伤情况，对临床制定治疗方案具有重要的应用价值。

Objective To investigate the clinical application and diagnostic value of three-dimensional and multiplanar reconstruction of spiral CT in fracture of shoulder blade. Methods The image of three-dimensional and muhiplanar reconstruction of spiral CT in fracture of shoulder blade cases were analyzed retrospectively. Results The 54 bone fractures were found in 31 fracture of shoulder blade cases;the multiplanar discovered 54 bone fractures, and could show the fracture line and small bone chips clearly, especially for the bone chips in articular cavity ,but it could not display the three-dimension of bone fracture;three-dimensional reconstruction discovered 51 bone fractures, and could display the change about three-dimension of bone fracture, but it could not show the fracture line of the bone fracture with small and non-dislocated clearly. Conclusion Three-dimensional and muhiplanar reconstruction of spiral CT were applied conjunctively can increase the accurate rate, and strengthen the sense of three-dimensional in fracture of shoulder blade ; in addition, it also could show the articular corresponding relationship and surrounding soft tissue injury, and offer the considerable value for the establishment of therapeutic regimen.
