摘　　要：目的探讨双源CT FLASH模式在儿童自由呼吸下肺部的应用价值。方法选取某院进行肺部检查的小儿患者60例,根据患儿年龄及体质量相似的分为A、B两组,A组采用双源CT FLASH模式进行扫描,患儿自由呼吸、无需镇静;B组采用肺部传统模式扫描,患儿需要镇静。对比两组图像的质量、辐射剂量及扫描时间有无统计学差异。结果 A组的图像质量得分要高于B组,A组的CT容积剂量指数(CTDIvol值)、剂量长度乘积(DLP值)、有效剂量(ED)以及扫描时间均低于B组,以上差异均具有高度统计学意义(P <0.001)。结论双源CT FLASH模式扫描速度快、无需镇静、辐射剂量低、图像质量好等优势,值得在临床工作中推广应用。Objective To explore the value of dual-source CT FLASH mode in children’s lung under free breathing.Methods A total of 60 children undergoing pulmonary examination in a hospital were selected and divided into two groups according to their age and weight.Group A was scanned by dual-source CT FLASH mode and breathed freely without sedation;Group B was scanned with traditional lung mode and needed sedation.The quality of scanning image,radiation dose and scanning time of the two groups were compared.Results The image quality score of group A is higher than that of group B.The CTDIvol value,DLP value,ED value and scanning time of group A were lower than those of group B and the above differences were statistically significant(P<0.001).Conclusion Dual-source CT FLASH mode had the advantages of high speed,no sedation,low radiation dose and good image quality,worth of promotion in clinical services.
