Abstract
Imaging features of brain arteriovenous malformations (AVMs) are critical for pretreatment planning and posttreatment decision-making. This chapter will describe the important, clinically relevant imaging features of brain AVMs as well as the relative advantages and disadvantages of the widely available imaging modalities: computed tomography (CT), magnetic resonance imaging (MRI), and digital subtraction angiography (DSA). These techniques often yield complementary information. Critical features include the size, location, and pattern of venous drainage, as well as the presence of intranidal or flow-related aneurysms. Imaging is critical for confirming cure of these lesions, particularly after stereotactic radiosurgery. Finally, we will review new and emerging applications of imaging for patients with brain AVMs, including the assessment of microhemorrhage as an indicator of increased bleeding risk for clinically asymptomatic brain AVMs.
