Vida Diagnostics of Iowa City, IA, has received approval from the U.S. Food and Drug Administration (FDA) for its Pulmonary Workstation 2.0 (PW2) lung image analysis software.
PW2 takes CT lung data and converts it into 3D images and measurements that can be viewed at the point of patient service or within a radiology department.
PW2 features include a number of lung or lobe volume and density measurements. In addition, airway, lung, and lobe measurement tools are combined with airway visualization to aid in patient assessment and procedure planning.

![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)
