Arteriograms evaluated using a two-degree grading scale of good and poor.
A, Right anterior oblique arteriogram of the left vertebral artery was evaluated as good. A small aneurysm of the right vertebral-basilar junction can be seen. Note a retrograde flow to the opposite vertebral artery.
B, Lateral arteriogram of the common carotid artery in a patient with a high flow arteriovenous malformation was evaluated as poor. Peripheral branches of the cerebral arteries are not well visualized.
