Positron emission tomography in moyamoya disease

Abstract

The hallmark features of moyamoya disease are a progressive occlusion of bilateral internal carotid arteries and the development of collateral networks to compensate for the reduced cerebral perfusion [1, 2]. Besides these very specific changes, several other conditions can also lead to the chronic cerebral ischemia encountered mainly in younger patients. It thus becomes necessary to evaluate the hemodynamic condition of patients with moyamoya disease in order to understand the pathophysiology of the syndrome and select appropriate treatments for patients individually. © 2010 Springer-Verlag Tokyo.
