Elucid Launches PlaqueIQ Image Analysis Software for Carotid Arteries

October 29, 2025—Elucid announced the launch of its PlaqueIQ image analysis software for the quantification and classification of plaque morphology in the carotid arteries.

According to the company, the CT-based PlaqueIQ software may help physicians both diagnose carotid plaques at risk for rupture and develop patient-specific treatment pathways to prevent and monitor against ischemic stroke.

PlaqueIQ, which includes the company’s noninvasive CT Virtual Histology, is capable of identifying and quantifying lipid-rich necrotic core—the plaque type strongly linked with both cardiovascular and cerebrovascular risk, stated Elucid.

The company further noted that PlaqueIQ is used for both the coronary and carotid arteries for a quantitative and qualitative assessment of systemic atherosclerotic risk and has the potential to perform both coronary and carotid plaque analysis in a single scan.

“The ability to characterize plaque composition precisely revolutionizes carotid stroke risk assessment,” commented vascular surgeon David Deaton, MD, in Elucid’s press release. “Plaque composition has long been recognized as a critical risk element for stroke but was not available with conventional imaging techniques. Precise determination of plaque composition supersedes the traditional stenosis assessment and allows a more accurate identification of patients at highest risk for carotid stroke and facilitates procedural choice and planning.”

Cardiologist Alberto Morales, MD, added, “For years, we’ve used CT to quantify coronary plaque and personalize prevention and now being able to do the same with the carotid arteries is a game changer. This technology finally lets us measure and monitor carotid plaque biology, not just anatomy, giving us a much more complete picture of stroke risk and overall vascular health. This is truly the future of vascular medicine.”
