Computer-aided detection (CAD) firm R2 Technology has released version 2.1 of its ImageChecker CT Lung CAD system.
The new release features expanded PACS integration and updates to the Pulmonary Artery Patency Exam (PE) tool according to the Sunnyvale, CA-based firm. Results from R2's AutoPoint temporal comparison tool used with long nodule detection can now be sent to a PACS workstation, R2 said.
In addition, R2's PE tool can now provide volume calculations for filling defects, according to the company. The tool is also now available separately from R2's lung nodule detection system.

![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)
