Siemens Medical Solutions has received U.S. Food and Drug Administration 510(k) clearance for four applications on its Somatom Definition dual-source CT scanner.
The new dual-energy applications are designed to simplify the diagnosis of diseases of the heart, brain, lungs, and extremity joints, according to the Malvern, PA-based vendor. One application, syngo DE Heart PBV provides color marking of nonperfused parts of the myocardium during cardiology examinations, Siemens said. It also provides for isolated display of the heart, such as without thorax structures.
Another new application, syngo DE Gout, aids physicians in identifying uric acid crystals in the extremities, Siemens said. syngo DE Lung Vessels provides a series of applications to assist in CT examinations of patients with suspected pulmonary embolism, while syngo DE Brain Hemorrhage aids in the distinction between new and old hemorrhages in cerebral bleeding, according to the firm.

![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)
