| 摘 要： | 目的探讨CT肺血容积坠积效应(VEPB)产生的原因。方法在2007年12月—2009年1月间在北京军区第261医院全部住院并行胸部CT检查的患者中随机抽取178例患者的胸部CT检查资料及临床资料,以胸部CT检查中发生坠积效应与否进行分组,分为阳性组和阴性组,结合临床资料中的年龄、性别及心功能状况进行回顾性分析,并进行统计学分析。结果坠积效应在该院住院患者中发生率为40.4%,95%可信区间为33.1%～47.7%;阳性组中50岁以上者的比例较阴性组高,差异有统计学意义(P0.01);阳性组中心功能欠佳者较阴性组高,差异有统计学意义(P0.05)。结论肺血容积坠积效应的发生与患者年龄以及心脏功能有关,与性别因素无关。
