【摘要】 目的:探讨儿童胸部CT增强中,两种移床方式对强化效果的影响及其相关因素。方法:以进床组为对照,研究退床组的强化效果;获取主要技术参数的平均值;分析两组强化效果和主要技术参数的差异。结果:两组病例的主要技术参数和强化效果均未发现显著差异。结论:无论采用哪种移床方式,强化效果仍然取决于参数整体的合理选定,而非任何单一因素。更多还原

【Abstract】 Objective:To explore the enhancement effect of two different bed-moving modes and their relative parameters in children’s chest CT checkup.Methods:The enhancement of out-bed group was studied with the in-bed group as control and the mean data of the major parameters were acquired.Then the enhancement effect and the major parameters were analyzed to make clear the differences presented in the two groups.Results:No difference was found between the two groups in enhancement effect and the data of major parameters.Conclusion:For each bed-moving mode,enhancement effect relied on the reasonable determination of the integrative parameters,but not a single one.更多还原
