Tóm tắt

In magnetic resonance imaging, stimulated-echo based phase-contrast displacement mapping has been developed for various applications. This paper describes the adaptation and technical optimization of this idea for mapping the three-dimensional (3D) motion of the left ventricular wall in the human heart. Percentile wall thickening maps are obtained with a rapid and automatic data processing program. Results from normal human subjects and swine infarct models show that this quantitative method is suited for detecting focal areas of abnormal wall motion.
