ABSTRACT

The radiographic diagnosis and characterization of cerebral arteriovenous malformations (AVMs) has undergone revolutionary changes with the developments of computed tomography (CT) and magnetic resonance imaging (MRI). Exquisite characterization of cerebral AVMs continues to evolve as these modalities are improved and expanded [e.g., CT angiography (CTA), magnetic resonance angiography (MRA), and functional MRI]. Together with conventional catheter angiography, the available imaging armamentarium permits highly accurate characterization of AVMs, enabling definitive therapeutic planning.
