Patient 1.
A, Lateral projection arterial phase image from digital subtraction angiogram of the right internal carotid artery.
B, Lateral projection arterial phase image from digital subtraction angiogram of the right vertebral artery.
C, Dual vessel injections provide better representation of the AVM nidus for radiosurgical planning. The right M1 vessel in this patient was stenotic, resulting in extensive leptomeningeal collaterals.

Patient 6.
A, Anteroposterior view angiogram of the left vertebral artery.
B, Anteroposterior view angiogram of the left internal carotid artery.
C, Dual vessel injections provide better representation of the entire nidus in a single biplanar image.

Patient 3.
A, Anteroposterior view angiogram of the left internal carotid artery.
B, Anteroposterior view angiogram of the left vertebral artery.
C, Dual vessel injections show an inferomedial component of the nidus (arrow) that is poorly visualized with the vertebral injection alone (see B).
