  • Look Inside

Arteriovenous malformations (AVMs) are usu-ally associated with diminished cerebral blood flow (CBF) in the parenchyma surrounding AVMs because of the steal phenomenon. Vasoreactivity in the parenchyma surrounding AVMs may change because of ischemia and abnormal hemodynamics. The aim of this study was to investigate vaso-reactivity in the parenchyma surrounding AVMs. Quantitative single-photon emission computed tomography using N-isopropyl-p-I-123 iodoam-phetamine (IMP-SPECT) was performed before and after intravenous administration of aceta-zolamide (Diamox).
