Bordeaux, France-based company Nurea has received U.S. Food and Drug Administration (FDA) clearance for its AI software for measuring aortic diameters on contrast-enhanced and noncontrast CT scans.
PRAEVAorta 2 is designed to support the diagnosis and patient follow-up in aortic aneurysm management, the company said. The software provides an automated reconstruction and analysis of the arterial tree from DICOM images and has the capacity to differentiate the lumen from the thrombus, which enables the extraction of multiple additional criteria not easily accessible for physicians, Nurea noted.
The software has also received the CE mark for use in Europe, the company 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&dpr=2&fit=crop&h=167&q=70&w=250)
