Look for GE to reprise last year's introduction of its VCAR (volume computer-assisted reading) software by highlighting the software again at this year's meeting.
VCAR is designed to detect pulmonary nodules on multislice CT examinations. The software combines automatic nodule detection with volumetric assessment at initial and follow-up studies, according to the Chalfont St. Giles, U.K., company.
The software also has the potential to calculate the proportion of tissular component in the case of mixed nodules, assess the range of densities in other nonsolid nodules, and evaluate their evolution over time, the company said. GE believes the combination of density distribution and volumetric analysis could be particularly important for the management of nonsolid nodules, especially the follow-up of lesions with ground-glass opacity and a great axis smaller than 10 mm.
VCAR has clearance from the U.S. Food and Drug Administration, and GE is shipping the product.

![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)
