ASL-MRI-guided evaluation of multiple burr hole revascularization surgery in Moyamoya disease.

ABSTRACT:

Purpose

Moyamoya (MM) disease is characterized by progressive intracranial arterial stenosis. Patients commonly need revascularization surgery to optimize cerebral blood flow (CBF). Estimation of CBF and cerebrovascular reserve (CVR) is therefore necessary before and after surgery. However, assessment of CBF before and after indirect revascularization surgery with the multiple burr hole (MBH) technique in MM has not been studied extensively. In this study, we describe our initial experience using arterial spin labeling magnetic resonance perfusion imaging (ASL-MRI) for CBF and CVR assessment before and after indirect MBH revascularization surgery in MM patients.

Methods

Eleven MM patients (initial age 6-50 years, 1 male/10 female) with 19 affected hemispheres were included.
