| 目的 研究多发伤患者在院治疗期间的累积医疗X射线检查剂量,探讨其影响因素。方法 回顾性收集2009年6月至2011年4月在本院治疗患者的CT、DR检查记录,CT记录其DLP值,并用各部位转换系数算出有效剂量;DR参照以往研究各部位有效剂量数据。结果 共收集113位患者的X射线检查的累积剂量,剂量范围16.48~153.3 mSv,平均(52.3±26.6)mSv。结论 多发伤患者其累积X射线剂量处于较高的水平。应加强对医疗X射线检查的累积剂量管理,通过建立患者X射线辐射剂量档案管理可能使临床医生、检查技术员重视检查开单的选择以及检查参数的合理设置。 |

| Objective To study the cumulative radiation dose of multiple trauma patients during their hospitalization and to analyze the dose influece factors.Methods The DLP for CT and DR were retrospectively collected from the patients during June, 2009 and April, 2011 at a university affiliated hospital.The cumulative radiation doses were calculated by summing typical effective doses of the anatomic regions scanned.Results The cumulative radiation doses of 113 patients were collected. The maximum, minimum and the mean values of cumulative effective doses were 153.3,16.48 mSv and(52.3±26.6)mSv.Conclusions Multiple trauma patients have high cumulative radiation exposure. Therefore, the management of cumulative radiation doses should be enhanced. To establish the individualized radiation exposure archives will be helpful for the clinicians and technicians to make decision wheather to image again and how to select the imaging parameters. |
