Intracranial arteriovenous malformations (iAVMs) are high-flow AV shunts that can affect perfusion of surrounding normal brain. Although controversial, vascular steal is thought to contribute to the risk of normal perfusion breakthrough. Knowledge of specific areas of vascular steal could alter endovascular and surgical strategies of treatment. Spin-echo perfusion acquisitions allow detailed mapping of areas of vascular steal in patients with iAVMs.
