(Booth 8513) Medrad of Warrendale, PA, is set to roll out its new CardiacFlow upgrade for the company's Stellant D CT contrast injection system. Designed to compute customized contrast injection protocols for each cardiac patient, this enhancement permits cardiac imaging during ECG gating.
In addition, Medrad will introduce a new patented safety feature for Stellant D, called the XDS extravasation detector technology. XDS couples radiofrequency waves with a physical property called permittivity that directly detects fluid pooling under the patient's skin. Once the system senses mild extravasation, it stops the injection to reduce the risk of a mild occurrence becoming moderate or severe.
XDS received clearance from the FDA in March 2007, and is commercially available.
![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)
