Automatic Identification of Blood Vessel Density Asymmetry for More Accurate Decisions in Patient Care

Rapid CTA maps include a colored overlay to identify brain regions with reduced blood vessel density. The severity of this reduction can be readily visualized by a simple, four-color-coded scale.

A 3D reconstruction of the vasculature allows the physicians to rotate the image for optimal viewing of blood vessels from multiple angles.

Patients with occlusions of the middle cerebral or internal carotid artery typically have a > 10% reduction in blood vessel density. A blue or green overlay identifies a mild reduction in blood vessel density.

The Rapid CTA map above shows a patient with a middle cerebral artery occlusion and poor collaterals, resulting in a severe reduction in vessel density and is identified in red.

Rapid CTA results include coronal views of the vasculature.

Rapid CTA provides a sagittal view for comprehensive viewing of the brain vessels.
