Patient groups and the prevalence of the RNF213 variant.
* Transfemoral cerebral angiography (TFCA) finding of moyamoya disease (MMD) indicate the presence of basal collaterals. †Time-of-flight magnetic resonance angiography (TOF-MRA) findings of MMD indicate bilateral appearance of an abnormal vascular network in the basal ganglia on the source image of MRA. ‡High-resolution magnetic resonance imaging (HR-MRI) findings of intracranial atherosclerotic stenosis indicate the absence of focal eccentric plaque and presence of negative remodeling and concentric enhancement. Abbreviations: ICA, internal carotid artery; MCA, middle cerebral artery, TFCA, transfemoral cerebral angiography; HR-MRI, high-resolution magnetic resonance imaging; MRA, magnetic resonance angiography; MMD, moyamoya disease; ICAS, intracranial atherosclerotic stroke.
