Siemens Healthcare has received clearance from the U.S. Food and Drug Administration (FDA) for its Somatom CT systems for low-dose lung cancer screening.
The indication for low-dose lung cancer screening is available for the following CT systems: Somatom Force, Somatom Definition Flash, Somatom Definition Edge, Somatom Definition AS/AS+, Somatom Perspective, Somatom Scope, and the Somatom Emotion 16.
With its Fully Assisting Scanner Technologies (FAST) features, Siemens optimizes CT acquisition by reducing user variability so technologists can set an optimum range for scan settings that avoids cutoffs or excessive radiation. And with its Combined Applications to Reduce Exposure (CARE) feature, Siemens delivers an approach to optimizing radiation dose in scan parameters that supports efficient clinical workflow, the firm said. Other features in the Somatom portfolio also aid the radiologist in reporting dose and sharing findings within the interdisciplinary lung cancer team.
![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)
