应用多导航技术和实时磁共振成像技术，对10名健康志愿者自由呼吸时右半膈、左心室、胸壁、腹壁等解剖部位的呼吸运动进行了研究。呼吸运动表现出滞后效应，这是强烈的主题依赖性，并可能对心脏MR图像的质量有一定的影响。
The respiratory motion of several anatomic regions (right hemidiaphragm, left ventricle of the heart, chest wall, abdominal wall) was investigated during free breathing in 10 healthy volunteers by using multinavigator technology and real-time magnetic resonance (MR) imaging. The respiratory motion shows hysteretic effects, which are strongly subject dependent and might have some effect on the quality of cardiac MR images.
