Rapid CTA and Rapid LVO

Fast Identification of Suspected LVOs to Streamline Triage & Transfer Decisions

In as few as three minutes, Rapid CTA and Rapid LVO help physicians quickly identify suspected large vessel occlusions (LVOs) by automatically processing CT scans and delivering clear, easy-to-interpret CT angiography images—helping to speed triage or transfer decision-making and facilitate better patient outcomes.


Clear Results for Better Decision-Making

Using color-coded overlays, Rapid CTA automatically identifies regions of asymmetry in brain regions with reduced vessel density and Rapid LVO quickly detects suspected large vessel occlusions—helping physicians and stroke teams make critical clinical decisions faster.

Fast Identification of Suspected LVOs

Rapid LVO detects suspected LVOs with a sensitivity of 97% and a specificity of 96%

Rapid CTA 2D Output

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.

Rapid CTA 3D Rotational Output

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

Good Collaterals

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.

Poor Collaterals

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 Coronal Views

Rapid CTA results include coronal views of the vasculature.

Rapid CTA Sagittal Views

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


Designed to Help Improve Patient Outcomes, Rapid CTA and Rapid LVO are:


Rapid LVO identifies suspected large vessel occlusions (LVOs)—delivering results and source files to team members via PACS, email, and the Rapid mobile and web apps in as few as 3 minutes.


Rapid CTA and Rapid LVO are validated, trusted products, developed by medical experts and clinicians worldwide are improving patient care and outcomes every day.


Rapid LVO with a sensitivity of 97% and a specificity of 96%— delivering clear, easy-to-interpret CT angiography images.
