Abstract
A magnetic resonance cardiac imaging method for imaging during a cardiac cycle interval includes monitoring an electrocardiographic signal (90) associated with the imaged heart for a first trigger event (102). Responsive to the first trigger event, a data acquisition sequence (112, 120) is applied, including a first preparation sequence block (114), a first imaging sequence block (116) having at least one readout interval (228) that collects first data (118), a second preparation sequence block (122), and a second imaging sequence block (124) having at least one readout interval (228) that collects second data (126). The data acquisition sequence (112, 120) occupies an acquisition time interval which is less than the cardiac cycle interval of the imaged heart.
