Abstract:
1. A method for magnetic resonance imaging of a heart of a subject, said method comprising: administering a contrast agent to the subject; applying a nuclear magnetic resonance preparation, comprising inversion rf-pulses, partial inversion rf-pulses, a saturation rf-pulse, or a partial saturation rf-pulse, to impart T1 contrast weighting to the myocardium of the heart; applying a motion-sensitization gradient preparation, comprised of a plurality of rf-pulses and a plurality of magnetic field gradients and configured to dephase a signal corresponding to blood within the heart relative to a signal corresponding to the myocardium, based on the inherent motion of the blood in comparison to motion of the myocardium and independent of T1 relaxation properties of the blood and movement of the blood relative to an imaging plane prior to image acquisition, such that the blood is rendered dark relative to the myocardium; and reading out a nuclear magnetic resonance signal from the heart.
