摘要
背景:螺旋CT三维重建技术尤其在解剖结构复杂、重叠较多的骨关节骨折中具有非常重要的应用价值,能够显著提高诊断率,减少漏诊率,为临床提供更多的诊断信息。目的:探讨了螺旋CT三维及多平面重建的应用原理及不同部位骨折中的临床应用。方法:应用计算机检索万方数据库、维普数据库和PubMed数据库中1999-01/2011-09关于多层螺旋CT三维重建技术在骨科领域应用的文章。选择文章内容与骨折及螺旋CT重建相关,同一领域文献则选择近期发表或发表在权威杂志文章。初检得到157篇文献,根据纳入标准选择30篇文章进行探讨。结果与结论:螺旋CT扫描后三维或多平面重建技术在骨折创伤检查中显示出重要的价值,它能很直观地显示骨折关节的损伤情况,有助于骨折正确分型,为骨科医师进行合适的治疗方案选择提供依据。随着多排螺旋CT的快速发展,三维CT重建技术更快捷、简单、实用,图像更加清晰,目前在计算机图像处理技术的基础上发展出了计算机辅助外科手术系统,与三维图像重建的有机结合可使临床医生能够更好的进行手术计划制定评估预后或治疗后随访,有较好的应用价值及前景。
BACKGROUND：Three-dimensional reconstruction technology of spiral CT has a very important value in bone fractures with complex anatomical structure and more overlapping,which can significantly improve the diagnostic rate,reduce the rate of misdiagnosis,and provide more diagnostic information in clinic.OBJECTIVE：To investigate the principle and clinical application of three-dimensional or multi-plane spiral CT reconstruction at different bone fracture sites.METHODS：A computer-based search of Wanfang,VIP and PubMed databases （1999-01/2011-09） was performed for articles related to multi-plane spiral CT reconstruction in orthopedics.Relevant articles published recently or in authorized journals were preferred.A total of 157 articles were retrieved and finally 30 met the requirement.RESULTS AND CONCLUSION：Three-dimensional or multiple-plane reconstruction after spiral CT scan shows an important value in the examinations of traumatic fractures,and it can visually display fracture damage of the joints,benefit to the right typing of fractures,and provide the basis for orthopedic surgeons to choose appropriate treatments.With the rapid development of multi-slice spiral CT,three-dimensional CT reconstruction is more efficient,simple and practical,and CT images become more clarity.Currently,a computer-assisted surgical system has been developed on the basis of computer image processing technology,which is combined with three-dimensional image reconstruction to enable clinicians to better assess the prognosis for surgical planning or follow-up after treatment.It has a good application value and future prospect.
