Neurological
MRA of vertebral artery dissection after trauma
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.

The diagnosis was occlusion of the left vertebral artery from C2 to C7 due to dissection of the left vertebral artery.
