目的探讨多层螺旋CT多平面重组及三维重组对复杂结构的隐匿性骨折的诊断.方法回顾性收集CT诊断骨折病例93例,分析隐匿性骨折及复杂结构骨折的最佳显示方法与DR片比较.结果 DR片未显示或细微骨折显示不清者而MSCT明确骨折31例;显示更多复合骨折16例;骨折碎片突入椎管或关节腔内17例.结论 MSCT扫描二维和三维重组对隐匿性骨折及复杂结构骨折的诊断具有很高的准确性和完整性,且明显优于DR片.所以临床怀疑骨折而DR片未显示或细微骨折显示不清者及复合骨折结构显示不清者,应当进行MSCT检查及软件处理予以弥补.

Objective To evaluate multi-slice CT(MSCT)with multi-planar reconstruction and 3D vol-ume rendering for diagnosis of incipient bone fracture in complex structure. Methods 93 cases of bone fracture with CT diagnosis were retrospectively collected. The best way to display the incipient fracture and complex structural fracture was analyzed,together with comparison to that presented by digital radiography(DR). Results The cases with non-visualization or unclear demonstration of delicate fractures by DR, could be accurately di-agnosed as fracture by MSCT in 31 cases,with furthermore diagnosis of complex fracture for in 16 cases,and fragmental protrusion into vertebral canal or joint space in another 17 cases. Conclusion MSCT with 2D or 3D volume rendering and software processing provide high accuracy and completeness for diagnosing incipient and complex structural fractures. It is superior to DR technology; especially in cases of non-visualized or unclear dis-played delicate or complex fractures.
