Rapid CTA

Quickly Detect and Locate LVOs When Every Second Counts

In as few as three minutes, Rapid CTA automatically assesses regions of reduced blood flow to identify, locate, and alert stroke teams to the presence of large vessel occlusions (LVOs)*. Across hospital systems and referral networks, Rapid CTA helps stroke teams make faster triage-or-transfer decisions—facilitating better patient outcomes and saving lives.

Clear Results for Better Decision-Making

Using color-coded overlays that automatically detect and help locate LVOs, distal occlusions, and vessel stenosis, Rapid CTA quickly identifies brain regions with reduced vessel density—helping physicians and stroke teams make critical clinical decisions faster.

Fast Detection of LVOs

Rapid CTA detects LVOs with a sensitivity of 96% and a specificity of 95%.

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.

KEY BENEFITS

Designed to Help Improve Patient Outcomes, Rapid CTA is:

  • Fast. Rapid CTA automatically detects, locates, and alerts stroke teams to the presence of LVOs—delivering results and source files to team members via PACS, email, and the Rapid Mobile App in as few as 3 minutes.
  • Proven. Rapid CTA is the only automated imaging technology indicated for LVO detection and localization.
  • Clear. Rapid CTA detects LVOs with a sensitivity of 96% and a specificity of 95%—with clear, easy-to-read results that outline detected LVOs for fast, easy identification and localization.
