动态三维CT处理软件OsiriX在颌面部骨折个性化重建中的应用

Dynamic three-dimensional CT-processing software OsiriX in the individual reconstruction of maxillofacial fractures

背景:充分地解读应用影像学数据信息,对于提高临床诊疗效率、降低患者辐射暴露并提高效费比具有重要意义。目的:利用OsiriX软件对螺旋CT扫描容积数据进行基于颌面部骨折病例的个体化重建与临床动态观测分析,通过与传统影像判读手段对比,评估新型影像处理平台在口腔颌面外科临床诊疗中的应用效能。方法:选取口腔颌面部骨折病例进行螺旋CT检查,所得数据在专业Dicom处理软件OsiriX平台进行三维可视化模型重建,进行重建前损伤评估、重建方案设计及重建后复位效果评估,并与传统影像学检查判读结果进行对比。结果与结论:通过OsiriX平台快速建立动态三维可视化模型,直观了解创伤程度,进行相关实时测量,针对性制定重建治疗方案。重建过程中同期对手术入路、术野显露范围进行对比,提高重建效率。重建后复查可有效对比评估治疗效果。提示该类软件在重建前分析及重建设计模拟方面具有独特优势,人机界面友好,操作方便,提高了医患交流效果。

BACKGROUND：Full understanding of imaging data is important to improve clinical diagnosis treatment efficiency,reduce radiation exposure and increase the cost-effective radio.OBJECTIVE：To use the OsiriX software for individual reconstruction and clinical analysis of maxillofacial fractures based on the spiral CT scan volume data,and by means of contrast with the traditional image interpretation to evaluate the application performance of new image processing platform in the clinical diagnosis and treatment of oral maxillofacial surgery.METHODS：The cases of oral and maxillofacial fractures were examined with spiral CT,the data were used in the OsiriX software platform to reconstruct three-dimensional visualization model for preoperative damage assessment,reconstruction program design,and postoperative reduction assessment,in comparison with the results of traditional interpretation.RESULTS AND CONCLUSION：Based on the OsiriX platform,we can quickly build a dynamic three-dimensional visualization model to have an intuitive understanding of trauma severity,perform the real-time measurement and make pointed reference to develop the reconstruction program.During the reconstruction process,the surgical approach and scope of the operative field are compared to improve the efficiency of reconstruction.Post-reconstruction review is effective to evaluate treatment efficiency.It is indicated that this software has unique advantages in the pre-reconstruction analysis and reconstruction program design,characterized as friendly interface and easy operation,which improves the doctor-patient communication results.
