Angioarchitectural Characterization of Target Collateral Vessels in Periventricular Hemorrhagic Moyamoya Disease: A Multimodal 5.0T MRI and DSA Study.
OBJECTIVE The goal of this study was to visualize and characterize the angioarchitecture of the target collateral vessels (TCVs) responsible for periventricular hemorrhage in patients with moyamoya disease (MMD) using a multimodal approach combining ultrahigh-field 5.0T magnetic resonance angiography (MRA) and digital...
