Dear AuntMinnie Member,
AuntMinnieTV returns for a winter run with Advances in CT Technology, a new series of segments on CT product news from last month's RSNA meeting in Chicago.
What's AuntMinnieTV? It's a special section of AuntMinnie.com that uses streaming video technology to showcase the latest clinical and business news in medical imaging. AuntMinnieTV's multimedia format lets you see for yourself how today's most advanced technologies work in a clinical environment.
Our new series brings you coverage straight from the RSNA exhibit floor at Chicago's McCormick Place. We interviewed the major CT vendors -- as well as one start-up CT firm -- and asked them to describe both the new products they're shipping now, as well as future technologies that may take years to come to market.
You can view the segments by visiting our AuntMinnieTV RSNA 2005 Video Gallery, available here. We'll be featuring a new CT vendor every week through January, so make sure to come back often.
![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)
