Abstract
Moyamoya disease and syndrome are typically described by their imaging features on
cerebral angiography, however advances in noninvasive imaging has allowed improved
anatomic and physiologic characterization of this vascular abnormality. Advanced imaging
complements the role of cerebral angiography, and when used appropriately can provide
valuable information regarding the diagnosis, treatment planning, and surveillance
in patients with moyamoya. Techniques to be aware of include computed tomography,
CT-angiography, Magnetic Resonance Imaging, MR Angiography (time-of-flight and dynamic
contrast enhancemed angiography), and perfusion imaging (CT perfusion, arterial spin
labeling perfusion, and nuclear medicine perfusion). With an appropriate understanding
and implementation of noninvasive techniques, this disease process can be better understood
allowing for improved patient management.
