Computer-aided detection (CAD) developer R2 Technology has launched its ImageChecker CT Lung Version 2.0 CAD software system and AutoPoint temporal comparison feature for use during review of multidetector-row CT chest exams.
The latest iteration of the visualization application features enhancements to R2's CT lung CAD algorithm as well as expanded PACS integration, according to the Sunnyvale, CA-based company.
An AutoPoint temporal comparison option uses automatic 3D registration to enable physicians to track nodule changes over time, R2 said.
The system also provides a tabular report featuring key images and information on nodule volume and density changes, as well as a nodule's estimated growth doubling time, a measure of the likelihood of the nodule being malignant, the developer said.

![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)
