Recent studies indicate that 123 I-iomazenil ( 123 I-IMZ) single-photon emission computed tomography (SPECT) can demonstrate neuronal viability. Although cognitive dysfunction has been recognized as an important issue in adult patients with moyamoya disease (MMD), no standard neuroradiological methods to define such conditions have been established. We examined the relationship between cognitive function and 123 I-IMZ SPECT before and after revascularization in patients with MMD. ⋯ Preoperative cognitive function was associated with 123 I-IMZ uptake in adult patients with MMD. After revascularization, cognitive function could be recovered in the viable areas of the brain, which is consistent with 123 I-IMZ SPECT findings.
