颌面骨64排CT三维重建技术的应用

目的:探讨64排CT三维重建技术对颌面骨病变的诊断价值。方法:回顾性分析我院2010年7月～2011年7月收治的27例颌面骨病变患者的临床资料,均行64排CT扫描检查及普通X线平片摄影检查,对显示情况进行对比分析,并与手术结果相对照。结果:X线平片、二维成像的诊断率分别为74.1%、85.2%,均显著低于螺旋CT三维成像的诊断率100.0%(P<0.05),三维成像能够立体地显示骨折的位置、形态、范围和类型,能清楚显示复杂颌面骨折的立体解剖图像及其与周围结构的关系。结论:64排CT三维重建技术对复杂颌面骨骨折具有较重要的临床诊断价值。

Application of 64-slice CT in the three-dimensional reconstruction of the maxillofacial bone

Objective: To investigate the value of 64-slice CT in the diagnosis of maxillofacial diseases.Methods: Data of 27 patients with maxillofacial bone lesions that were admitted to our hospital during July 2010 and July 2011 were retrospectively analyzed.All patients underwent 64-slice CT scan and X-ray examination,and the diagnosis revealed by the CT and X-ray were compared with each other,and also compared with what were revealed by surgery.Results: The accuracy rate of X-ray and two three-dimensional images were 74.1% and 85.2%,both were significant lower than 100.0% of 64-slice CT(P<0.05).Three-dimensional images can reveal the location,shape,and type of the lesions,thus can clearly show anatomical images of complex maxillofacial fractures and their relationship with surrounding structures.Conclusions: The three-dimensional reconstruction technology of 64-slice CT shows important value in the diagnosis of complicated maxillofacial diseases.
