(Booth 9113) Covidien of Hazelwood, MO, will feature products from its Imaging Solutions business as it launches a new CT contrast delivery system that offers radiofrequency identification (RFID) technology.
The combined system is designed to help radiologic technologists deliver the prescribed concentration and programmed dose of contrast media during CT procedures. In addition, the approach indicates if an RFID-labeled syringe has been used, is empty, or has passed its expiration date. This safety capability is designed to reduce opportunities for life-threatening air injections or cross-contamination from more than one use of a given syringe. RFID transponders, or tags, provide the basis of the system.
The Optivantage equipment also facilitates documentation of the contrast used for the exam protocol by printing a label that can be placed into the patient record.
![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)
