Overview
Elucid PlaqueIQ is an AI-powered medical imaging software that provides quantitative analysis of coronary and carotid plaque composition using CT angiography (CTA). It leverages CT Virtual Histology™, trained and validated on ground-truth histopathology, the gold standard for plaque characterization. The software quantifies and classifies plaque morphology, identifying lipid-rich necrotic core, calcified, and non-calcified components. PlaqueIQ delivers an actionable report with 3D visualization of vessel structure, critical arterial volumes, and plaque quantification, enabling patient-specific treatment pathways. It integrates into existing clinical workflows via DICOM-wrapped PDFs delivered to PACS and an interactive browser for detailed coronary tree interrogation. The underlying algorithms demonstrate excellent correlation and accuracy for tissue characterization when compared to ex vivo histopathology, providing physicians with comprehensive patient, vessel, and lesion-level plaque composition and quantification data. Elucid FFRCT, currently under development, will leverage histology-based plaque composition to calculate lesion-level FFRCT measurements.
