Abstract： 目的探讨MR屏气电影成像技术评价左室功能的价值.方法应用屏气电影法MRI对18例健康成年志愿者和36例心脏病患者进行检查,并对左室容量和心肌质量进行测量,将屏气电影法MRI的结果与传统电影法MRI及超声心动图进行比较.结果 (1)屏气电影法与传统电影法MRI及超声心动图所得舒张末期容量(EDV)、收缩末期容量(ESV)、射血分数(EF)相关性良好,相关系数为0.52～0.96,3 种方法所测各指标的均值间比较差异无显著性意义(P>0.05).(2)3种方法所测舒张末期心肌质量(EDM),收缩末期心肌质量(ESM)相关系数较前3个指标低,且MRI与超声心动图所测ESM的均值差异有显著性意义(P<0.05),MRI与超声心动图ESM测量的一致性欠佳.结论屏气电影法MRI与传统电影法MRI、超声心动图比较,各心功能指标测量准确,相关性好,且成像时间短,无呼吸运动伪影,是1种临床实用价值很高的技术.
