Abstract

The recent advent of magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) has contributed significantly to the diagnosis of moyamoya disease. According to the guidelines for the diagnosis and treatment of spontaneous occlusion of the circle of Willis, i.e., moyamoya disease, cerebral angiography is not mandatory, if MRI and MRA identify all the findings required for diagnosis [1]. © 2010 Springer-Verlag Tokyo.
