Several GE Healthcare CT scanners have been cleared by the U.S. Food and Drug Administration (FDA) to perform low-dose lung cancer screening.
All new GE CT scanners at 64 slices and higher, as well as virtually all the 16-slice CT scanners that GE sells, are qualified systems under the clearance and will include the screening option.
In addition, low-dose CT lung cancer screening is also available to thousands of other scanners currently in use, GE said. The screening option includes new low-dose screening reference protocols tailored to the CT system, such as patient size, and recommendations from a wide range of professional medical and governmental organizations.
GE is also noting that the new protocols can utilize GE's dose reduction technologies such as adaptive statistical iterative reconstruction (ASiR), ASiR-V, and Veo, which are designed to reduce image noise that can be problematic for physicians looking for small lung nodules.
![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)
