A new MRI tagging technique combining multiple measurements with different grid positions achieves highly improved resolution of cardiac motion data in two short breath-hold periods.
Does a new MRI tagging technique combining multiple measurements with different grid positions improve the resolution of cardiac motion data?
A novel MRI tagging technique combining multiple measurements with different grid positions significantly improves the spatial resolution of myocardial motion tracking.
Magnetic resonance imaging with preceding tissue tagging is a robust method for assessing cardiac motion of the entire heartbeat cycle with a high degree of accuracy. One limitation of this technique, however, is the low resolution of the obtained displacement map of the labeled points within the myocardium. By a new tagging technique, which is based on the combination of two or more measurements of the same slice but with different grid positions, a highly improved resolution of cardiac motion data can be achieved. In combination with a multi-heart-phase echo-planar imaging sequence, such images with doubled grid frequency can be acquired in two short breath-hold periods.
