摘要

本文提出了左室壁运动分析方法和左室壁运动显示方法。为了准确地了解心脏壁的运动，比如它的旋转或变形，必须在心脏上找到可识别的标志。MRI标记可以无创地估计局部壁运动。标记是通过选择性饱和脉冲法实现的。我们试图通过MRI标记来估计精确的左室壁运动。标记区域和未标记区域之间的信号强度差异持续400-700 ms。我们以动画的形式显示左心室壁的标记点运动。

Image analysis of left ventricle wall motion by MRI tagging

We have developed a left-ventricular (LV) wall motion analysis method and a display method of the LV wall motion. To know the precise wall motion, such as its rotation or deformity, identifiable landmarks must be located on the heart. MRI tagging makes it possible to estimate the regional wall motion non-invasively. Tagging is achieved by the selective saturation pulse method. We tried to estimate the precise LV wall motion by MRI tagging. The difference in the signal intensity between the tagged and non-tagged regions persisted for 400-700 ms. We displayed the tag-point movement of the LV wall as an animation.
