Localizer and phase contrast MR images of a single cardiac
cycle in a northern elephant seal.
Sequential axial images were
obtained from a northern elephant seal pup. Localizer images (left) show the
position of the aortic bulb and pulmonary artery. In the corresponding phase
contrast images (right), image intensity is proportional to the velocity
component of the blood along the superior/inferior direction. Black indicates
superior (cranial) flow and white represents flow in the inferior (caudal)
direction. Thirty-two frames represent a complete cardiac cycle.
