我们的目的是通过电影磁共振成像（MRI）确定左心室和右心室质量和功能的正常范围，并确定性别差异。75例健康受试者（年龄范围8-55岁，平均28岁）进行了电影MRI研究。对10只犬进行了尸检确认成像，实际质量和MRI测定质量之间的平均差异为0.2 A +/- 8.4 g。观察者内和观察者间变异性以及研究间变异性为5- 6%。除射血分数和左心室质量与舒张末期容积比外，所有参数在男性和女性之间均存在显著差异。与已发表的尸检系列（包括性别差异）的一致性极佳。本研究提供了标准MRI数据，可用于比较个体患者和进一步研究右心室和左心室。互动
Our objective was to establish normal ranges of left and right ventricular mass and function with cine magnetic resonance imaging (MRI) and to determine gender differences. Seventy-five healthy subjects (age range 8-55, mean 28 yr) were studied with cine MRI. Ten dogs were imaged for autopsy validation with a mean difference between actual and MRI-determined mass of 0.2 A +/- 8.4 g. Intra observer and inter-observer variability and interstudy variability were 5-6%. All parameters were significantly different between males and females except ejection fraction and the left ventricular mass to end-diastolic volume ratio. Agreement with published autopsy series, including gender differences, was excellent. This study presents normative MRI data that can be used for comparing individual patients and for further study of right and left ventricular. Interaction.
