摘要 目的探讨低剂量自适应迭代重建技术(AIDR3D)对胸部低剂量CT扫描图像质量及辐射剂量的影响。方法回顾性分析2018年1月至2019年2月106例在该院门诊部行胸部CT检查患者的临床资料,依据检查方法不同分为对照组(常规低剂量胸部CT检查,n=46)和试验组(在对照组基础上联合AIDR3D进行检查,n=60),比较两组图像质量(噪声、伪影、细小结构显示、胸部病变显示评分)、辐射剂量[容积CT剂量指数(CTDIvol),剂量长度乘积(DLP)]。结果试验组噪声、伪影、细小结构显示、胸部病变显示评分明显低于对照组,差异有统计学意义(P<0.05);试验组CTDIvol、DLP明显小于对照组,差异有统计学意义(P<0.05)。结论将AIDR3D应用于胸部低剂量CT扫描中不仅可提高图像质量且能有效降低辐射剂量,有助于早期发现和诊断胸部疾病。
