摘　　要：目的探讨X线数字断层融合技术在茎突测量中的应用价值。方法用数字X线机和多层螺旋CT分别进行断层摄影和CT扫描检查30例茎突综合征患者。在各自的后处理工作站上重建调整检查图像,测量两种检查方法下同一个体茎突正侧位长度和角度。结果两种方法检查茎突长度和方位角均显示清晰。数据显示,用数字X线断层与CT检查茎突正位上测得的长度、内倾角和侧位上测得的前倾角,两者无显著差异(P>0.1);侧位断层图像上测量茎突的长度明显小于CT的测量值,此差异具有统计学意义(P<0.01)。结论 X线数字断层融合技术测量茎突长度应以正位为准。用X线数字断层融合技术测量茎突基本上可达到CT测量的标准,而且该技术操作简单,辐射量小,相对经济,应成为茎突综合征患者的首选影像学检查方法。Objective To investigate the clinical value of digital tomosynthesis in the diagnosis of the styloid process syndrome.Methods The thirty patients suspected of the styloid process syndrome underwent both multi-slice spiral CT scanning and digital tomosynthesis scanning.Two kinds of imaging were analyzed,and the length and angle of styloid on lat-eral and AP views were measured.Results Both images could clearly show the styloid length,size,shape,direction and the relationship with surrounding structures.There was no significant difference in the length,medial angle in the AP posi-tion and anterior angle in the lateral position between multi-slice spiral CT scanning and digital tomosynthesis scanning （P〉0.1）.The styloid length on lateral digital tomosynthesis was significant smaller than that on multi-slice spiral CT scanning（P〈0.01）.Conclusions The length of styloid measured should take the AP position as the standard using the digital tomosynthesis technique,which improve the image quality during the diagnosis of the styloid process syndrome and is less coitly and at a lower dose of radiation.Digital tomosynthesis could provide extensive clinical information and preoperative preparation of the very high referential value as CT canning.
