TL;DR
Multimodal MRI metrics provide imaging evidence linking macrovascular stenosis to CSVD, and Hemodynamic disturbance is associated with diffuse white matter injury, which may contribute to WMH formation.
Perivascular diffusion imaging and white matter free water capture complementary aspects of altered perivascular diffusion and extracellular free-water accumulation in cerebral small vessel disease and improve identification of MoCA-defined cognitive impairment beyond conventional structural magnetic resonance imaging...
FDG-PET demonstrated a numerical association between carotid stenosis severity and reduced cerebral glucose metabolism, but this did not reach statistical significance.
Increased WMH burden was independently associated with IA rupture, suggesting that aneurysm rupture may be influenced not only by local aneurysm morphology but also by diffuse cerebrovascular vulnerability.
BACKGROUND Cerebrovascular dysfunction contributes to mild cognitive impairment (MCI), but the complementary value of arterial spin labeling (ASL)-derived cerebral blood flow (CBF) and breath-hold cerebrovascular reactivity (CVR) for multivariate MRI classification remains unclear. PURPOSE/HYPOTHESIS To determine whe...
In MCA bifurcation aneurysms, M1 geometry differed between the aneurysm ipsilateral and contralateral sides, which warrant further validation in larger independent cohorts.
Objective The larger (≧1 mm) conducting and distributing arteries to the brain are sources of collateral during acute stroke, and include the cervical carotid, ophthalmic, and Circle of Willis (CoW) vessels. This study assessed their anatomy for relationships with stroke severity in large vessel occlusion (LVO), and wi...
