NO
To clarify the clinical significance of diffusion MRI named neurite orientation dispersion and density imaging (NODDI) and intravoxel incoherent motion (IVIM) in patients with moyamoya disease.
Others
1. To clarify the relationship of neurocognitive function and brain microstructure by comparing diffusion MRI parameters with scores of neurophysiological tests
2. To clarify the effect of chronic ischemia on brain microstructure by comparing diffusion MRI of patients with moyamoya disease and of age-sex matched normal healthy volunteers.
3. To verify the cerebral perfusion model of diffusion MRI and to clarify the relationship of cerebral metabolic and brain microstructure by comparing diffusion MRI and 15Ogas PET
Confirmatory
Explanatory
Not applicable
1. Comparing diffusion MRI parameters (ADC, FA, Vic, Viso and OD of NODDI) with scores of neurophysiological tests( WISC or WAIS, WCST, stroop test, word fluency test, TMT, and the BIg Five Personal Inventory or NEO-FFI)
2. Comparing diffusion MRI (ADC, FA, Vic, Viso and OD of NODDI) of patients with moyamoya disease and of age-sex matched normal healthy volunteers.
3. Comparing diffusion MRI(D* and f map of IVIM, and ADC, FA, Vic, Viso and OD of NODDI) and 15Ogas PET (CBF, CBV, OEF and CMRO2).

This study revealed that patients with moyamoya disease suffer from chronic ischemic damage to the brain microstructure, i.e. decreased neurite density and simplified network complexity, and the degree of ischemic damage is related to neurocognitive dysfunction and the degree of hemodynamic and metabolic dysfunction. We also found that diffusion magnetic resonance imaging might be used to noninvasevely evaluate cerebral hemodynamic impairment in patients with moyamoya disease.
