Animated gifs showing both respiratory and cardiac motion-resolved representative magnitude and phase images of a patient with thoracic aortic aneurysm and a heart rate of 50 beats per minute (shown in Fig 4A). Within each of the four image matrices, each column depicts the magnitude and phase images for an axial, coronal, and sagittal view of the heart and great vessels. The top row represents magnitude, first row velocity in the x direction, followed by velocity in the y and z directions. Resp position 1 corresponds to end expiration, while 4 corresponds to end inspiration.
