Viz.ai plans to highlight data gleaned from a large hospital network based in Texas that demonstrates the efficacy of its Viz Aneurysm software at the upcoming Society of Vascular and Interventional Neuroradiology (SVIN) meeting in Los Angeles.
Viz Aneurysm automatically analyzes CT angiograms for suspected cerebral aneurysm and facilitates referrals, allowing for better diagnosis and patient care, Viz.ai said. In the hospital network, it was used with 1,200 CT angiograms for stroke evaluation across eight stroke centers; of these, 85% of the aneurysms detected by Viz Aneurysm had not been previously referred for follow-up. The median size of all aneurysms was 5 mm and 45% were larger than 7 mm, according to the firm.
![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)
