Elucid's Lesion Inspection Tool for the company's Plaque-IQ software suite is now commercially available, allowing physicians to analyze plaque composition and burden at the individual lesion level in coronary and carotid vessels.
The tool provides quantitative results for specific vessel segments, including quantification of high-risk plaque features such as lipid-rich necrotic core (LRNC). Plaque-IQ is powered by CT-Virtual Histology technology, which noninvasively quantifies and classifies coronary and carotid plaque components using CT imaging.
Elucid noted that by focusing on lesion-level plaque biology rather than population-based risk estimates, Lesion Inspection Tool is designed to help physicians prioritize and personalize treatment for individual patients.
![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
