Moya-Moya disease is a rare arterial occlusive disease affecting the internal
carotid artery and its branches. It is found in both pediatric and adult
populations, and it may lead to severe clinical presentations such as stroke and
intracranial hemorrhage. Several surgical procedures have been developed to
improve its clinical outcome. Imaging techniques have a key role in management of
Moya-Moya disease, as they are necessary for diagnosis, choice of treatment and
follow-up. Although catheter angiography remains the diagnostic gold standard,
and nuclear-medicine techniques best perform hemodynamic studies, less invasive
imaging techniques have become efficient in serving these purposes. Conventional
MRI and MR angiography, as well as MR functional and metabolic studies, are now
widely used in each stage of disease management, from diagnosis to follow-up. CT
scan and Doppler sonography may also help assess severity of disease and effects
of treatment. The aim of this review is to clarify the utility, efficiency and
latest developments of each imaging modality in management of Moya-Moya disease.
