Figure 7From: Three-dimensional observation of Virchow–Robin spaces in the basal ganglia and white matter and their relevance to idiopathic normal pressure hydrocephalusAbsence of an artery in the Virchow–Robin spaces (VRS) in the white matter in a control subject. Multi-planar reconstruction constructive interference in the steady state (CISS) image (black and white) and magnetic resonance angiography (MRA) fusion image (color) in the white matter. CISS image showed VRS as round or tubular structures (circles) at subcortical (a) and periventricular (b) levels. Fusion image did not show any arteries in VRS; observation in a normal 69-year-old man.Back to article page
