In this paper presentation, researchers will highlight the advantages of automated 3D quantitative coronary plaque analysis.To improve risk stratification and monitoring of coronary artery disease, the researchers have recently developed software for automated noninvasive measurement of coronary plaque from CT angiography studies, said presenter Damini Dey, PhD, of Cedars-Sinai Medical Center in Los Angeles.
Following up on previous work -- published in the November 2010 issue of Radiology -- that found agreement between the software and invasive ultrasound for quantifying noncalcified plaque, the researchers sought to validate the automated quantitative plaque analysis and coronary artery remodeling index in comparison with expert readers.
"Our study shows that our automated plaque analysis allows close agreement with expert readers, at a fraction of the time needed," Dey told AuntMinnie.com. "The automated tool in this study could potentially be applied routinely to provide rapid, noninvasive quantitative assessment of coronary plaques from coronary CT angiography."
![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)
