| 1. A method of displaying cardiac information of a patient having a cardiac cycle, comprising:
obtaining a plurality of MRI cine loops of the heart of the patient at a plurality of heart rates, the plurality of cine loops
including cine loops including frames of wall motion images at different heart beat rates and at least one cine loop including
frames of perfusion images of at least one cardiac location;
synchronizing images in the wall motion cine loops so that heart motion at the different heart beat rates correspond to the
same portion of the cardiac cycle and adjusting the at least one perfusion cine loop to have the same number of frames as
the wall motion cine loops; and
simultaneously displaying both wall motion cine loops and the at least one perfusion cine loop.
