Angio-CT of the cephalad arteries in the spatial projection presentation (VRT).The left common carotid artery (a), the right common carotid artery (b), the right vertebral artery (c), and the right subclavian artery (d) branch off from the aortic arch. The left subclavian artery (f), critically narrowed at the ostium (g), leaves in the immediate vicinity of the origin of the ductus arteriosus (h). The left vertebral body (e) is at least twice as narrow as the contralateral vertebral body (c).

MR angiography of cephalad arteries using the TOF technique.Source image from the level of the C1 vertebra. The right vertebral column (a) is much wider than the left one (b). A high signal indicates the cephalad direction of flow in the vessels.
