Fig. 3From: Association between the vertebrobasilar artery geometry and basilar artery plaques determined by high-resolution magnetic resonance imagingSchematic diagram of vascular curvature in vertebral artery. Two 5 mm long lines were drawn starting from the vertex of a vascular curve to both sides, the two lines intersect with the VA to form an angle. a vascular bend was identified If this angle was ≤ 150°Back to article page
