目的观察数字X线断层融合摄影及常规DR摄影在诊断骶尾骨外伤中的表现,寻找X线摄影诊断骶尾骨外伤的更好方法.方法 38例近期有骶尾部外伤史患者分别行骶尾部正侧位DR摄影及侧位数字X线断层融合摄影,分析两种方法图像质量及诊断结果.结果 38例骶尾骨正侧位DR优质图像率为52.1％,阳性诊断率为8.3％；而侧位X线断层融合优质图像率为93.8％,阳性诊断率为33.3％.两种方法比较差异有统计学意义.结论骶尾骨X线断层融合摄影图像清晰,辐射剂量低,有望成为骶尾部外伤患者的首选检查方法.

Objective To observe the manifestation of X-ray digital tomosynthesis and normal digital radiography in the diagnosis of sacrococcyxlatera injury,in order to find out the best way for diagnosis of sacrococcyslatern injury.Methods Both X-ray and digital tomosynthesis scanning were performed in 38 cases of sacrococcyxlatera injury.Two kinds of imaging were analyzed with regard to image quality and diagnosis of abnormal sacrococcyxlatera.Results Among the 38 cases,image quality of sacrococcyxlatera was better with digital tomosynthesis(excellent irnage rate was 93.8％) than with X-ray (positive diagnostic rate was 52.1％).Sixteen cases with sacrococcyxlatera fracture and/or dislocation were found by digital tomosynthesis scanning,and only 4 cases was found by X-ray.Conclusions X-ray digital tomosynthesis technique can improve the image quality of lateral position' s imaging of sacrococcyxlatera,it has low-dose radiation.So it is expected to become the preferred method in patient with sacrococcyxlatera injury.
