Ghosting artifact of the aorta

Discussion:

This is a typical example of phase-encoded artifact secondary to aortic pulsation. The ghost images of the aorta are: discrete, well defined, lining with the aorta along the short axis of the abdomen (AP axis), regular interval distance between them (depend on the time of repetition), and extending beyond the field of view anteriorly and posteriorly. These features help recognize them and not to confuse them with any pathology.
