CT三维重建复查在诊断肋骨骨折中的价值及短期最佳复查时间窗的研究

The Value of CT Three-dimensional Reconstruction in Diagnosis of Rib Fracture and the Study of Short-term Optimum Time Window for Review

目的:探讨CT三维重建复查在肋骨骨折诊断中的作用以及短期内复查的最佳时间段选择,以期探明肋骨骨折的最佳检查策略。方法:回顾性分析我院2016年1月~2019年2月间266例胸部外伤患者行CT三维重建首诊并复查的影像资料,比较首次检查与复查诊断的肋骨骨折数量是否存在统计学差异;将短期40天内多次复查的病例分为两组,一组为外伤后1~20天复查组,另一组为外伤后21~40天复查组,分析两组CT三维重建复查诊断肋骨骨折的数量是否有统计学差异。结果:CT三维重建复查诊断肋骨骨折的准确率高于首次CT三维重建检查,差异具有统计学意义;外伤后21~40天内复查与伤后1~20天内复查诊断肋骨骨折数量存在差异,并且存在统计学意义。结论:CT三维重建复查诊断肋骨骨折能力明显优于伤后首次CT三维重建检查;伤后21~40天是肋骨骨折短期内最佳复查时间窗。

Objective To explore the role of CT three-dimensional reconstruction in the diagnosis of rib fracture and the best time for short-term review,in order to find out the best examination strategy for rib fracture.Methods The imaging data of 266 patients with thoracic trauma who underwent CT three-dimensional reconstruction from January 2016 to February 2019 were retrospectively analyzed.The number of rib fractures diagnosed by CT three-dimensional reconstruction was compared between the first and second examinations.The patients who underwent multiple examinations in a short period of 40 days were divided into two groups,one group was 1~20 days after trauma,the other group was 21~40 days after trauma.To analyze whether there is statistical difference in the number of rib fractures diagnosed by three-dimensional reconstruction of CT between the two groups.Results The accuracy of CT three-dimensional reconstruction in the diagnosis of rib fracture was higher than that of the first CT three-dimensional reconstruction.There was a significant difference in the number of rib fractures between 21~40 days after trauma and 1~20 days after trauma.Conclusion CT three-dimensional reconstruction is superior to the first CT three-dimensional reconstruction in the diagnosis of rib fracture.21~40 days after injury is the best time window for short-term review of rib fracture.
