Circle Cardiovascular Imaging has expanded its cvi42 cardiovascular imaging platform to include vascular CT analysis.
This comes through a collaboration with Astute Imaging, whose AI-driven vascular analysis technology has been integrated into the platform.
The new capability allows clinicians to analyze vascular anatomy for diagnosis, endovascular procedure planning, and post-treatment surveillance within the same platform used for cardiac imaging. Astute Imaging's algorithms support automated segmentation, quantification, and visualization of vascular structures.
The cvi42 platform is currently used in more than 1,700 hospitals across more than 90 countries, the firm said.
![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&fit=crop&h=100&q=70&w=100)
