Artificial intelligence (AI) software developer RapidAI has secured U.S. Food and Drug Administration (FDA) 510(k) clearance for its Rapid RV/LV software.
Available as part of the firm's Rapid PE detection and analysis software for suspected cases of pulmonary embolism (PE), the RV/LV software automatically calculates an important indicator of PE severity -- the ratio between the right and left ventricles -- on CT pulmonary angiograms, RapidAI said. Results are available within minutes, enabling care teams to more quickly prioritize patients and speed up decision-making, according to the vendor.
![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)
