摘要
目的:探讨多层螺旋CT与MRI在颌面部软组织测量中的应用价值。方法:12例口腔颌面正畸病例,行X线头影摄片、多层螺旋CT和MRI检查,分别测量颌面部软组织角度参数与软组织线距参数,采用SPSS11.0软件包对数据进行方差分析。结果:X线头影摄片、多层螺旋CT与MRI测量颌面部软组织角度参数与软组织线距参数测量值间无显著差异(P>0.05),MRI在显示颌面部软组织层次、结构上具有优势,螺旋CT在同时显示颌面部硬、软组织结构上具有优势。结论:螺旋CT与MRI在颌面部软组织测量中都有较高的实用价值;MRI在颌面部软组织测量上优于螺旋CT与X线测量。
PURPOSE:To evaluate the value of multi-slice CT and MRI on maxillofacial region soft tissue measurement.METHODS:A total of 12 cases of dentofacial orthodontic underwent X-ray photograph, multi-slice CT and MRI scanning.The angle and distance of maxillofacial region soft tissue were measured respectively.All data were analyzed statistically for ANOVA with SPSS11.0 software package.RESULTS:There was no significant difference among the three measurement methods:X-ray photograph, multi-slice CT and MRI(P〉0.05).MRI had advantages on depicting hierarchical structure of maxillofacial region, especially soft tissues, while multi-slice CT had advantages on depicting structure of maxillofacial region, both hard and soft tissues.CONCLUSIONS:Multi-slice CT and MRI are useful on maxillofacial region soft tissues measurement.MRI is superior to multi-slice CT and X-ray photograph on maxillofacial region soft tissue measurement.
