目的：探讨直接数字化X线摄影（DR）在外伤性肋骨骨折中的诊断价值。方法抽取在我院经直接数字化X线摄影（DR）检查后据CT三维重建及随访确定诊断的外伤性肋骨骨折患者50例，对其影像资料进行回顾性分析。结果50例胸部外伤患者经直接数字化X线摄影检查发现肋骨骨折89处，与CT三维重建及随访确定诊断的肋骨骨折101处相比，其准确率为88.1%。结论直接数字化X线摄影（D R）对于肋骨骨折不仅具有较高的诊断准确率，还具有操作简便、直接、快速、无需特殊准备等优势，值得临床推广应用。“,”Objective:To investigate the diagnostic value of direct digital X-ray radiography (DR) in traumatic rib fractures.Methods:50 patients were first examined by DR,then diagnosed as traumatic rib fractures by CT three-dimensional reconstruction and folow-up.The image data of them were analyzed retrospectively.Results:DR examination revealed 89 rib fractures;three dimensional reconstruction of CT and folow-up confirmed 101 rib fractures;This means that the accuracy of DR was 88.1%.Conclusion:For rib fractures,DR not only has a high diagnostic accuracy,but also has the advantages of simple operation,direction,quickness,no special preparation,etc.
