NEW! Medis QGuideCT release

NEW! Medis QGuideCT®

Unlock CT-derived coronary plaque insights for informed interventions.

A highly automated analysis performed on any existing coronary CTA.

QGuideCT¹ extracts and labels the coronary tree automatically, including main epicardial vessels and side branches, and renders a 3D reconstructed visualization of the analyzed vessels which can be made actionable for determining treatment paths.

¹QGuideCT is a registered trademark of Medis Associated BV. QGuideCT 1.0 has received US market clearance from the FDA. CE certification pending for this device. Not for clinical use in the EU.

QUESTION 1: Where is the plaque and what is it made of?

• The whole tree, not one slice. Plaque is quantified continuously along the vessel rather than judged from a single cross-section.
• Automated extraction of the coronary tree and centreline, with automated vessel labelling.
• Reader stays in control. Intuitive and easy to use longitudinal and transversal contour editing possible when needed.

Plaque composition colour key

Reported per vessel: volume by component (mm³) · total plaque (mm³) · lesion length (mm) · plaque burden (%) plus a total plaque volume across all vessels of interest.

3D reconstructed visualization from a standard coronary which enables intuitive visualization of the plaque distribution as demonstrated in the P4 trial.

QUESTION 2: How does that change the treatment plan?

• Plan the case, not just the diagnosis. The 3D reconstruction aids in determining treatment paths before the patient is on the table.

• Calcium strategy decided in advance. Where the calcium sits along the lesion informs whether lesion preparation is needed, and which kind.
• Sizing and landing zones. Lesion length and plaque burden are measured on CT rather than estimated during the procedure.

What reaches the table

• Intuitive 3D Visualization

• Plaque burden

• CAD-RADS 2.0 report

• Wireframe view with calcium distribution

• Patient-specific angiographic views

• Lesion length measurements

Cath Lab View: the wireframe view easily shows the extend and distribution of calcium along the vessels.
