Radiology Cases of Vertebral Artery Dissection
MRA with contrast of the neck in AP (left) and left oblique (middle) and right oblique (right) projections shows the right vertebral artery arises from the right subclavian artery and courses normally to where it enters the basilar artery. The left vertebral artery arises from the left subclavian artery but then is only faintly visualized along its course until it reconstitutes where it enters the basilar artery.
