Dear AuntMinnie Member,
CHICAGO - Radiology needs to go boldly into the uncertain future of healthcare, according to the opening address at RSNA 2015 today.
That advice, paraphrasing Captain Kirk of "Star Trek" fame, was given by Dr. Ronald Arenson of the University of California, San Francisco, who told RSNA attendees that despite the specialty's challenges, there is still a lot to be optimistic about.
Healthcare's growing demand for evidence-based medicine will build on the type of technologies that radiology has mastered, such as RIS and PACS, Arenson said.
And in a follow-up address, Dr. Darrell Kirch, president and CEO of the Association of American Medical Colleges, talked about how academic centers can lead the charge in reforming healthcare, through examples such as changing the dominant culture in healthcare enterprises and developing new care models.

In other news from RSNA 2015, Dutch researchers presented results suggesting that nodules detected with CT at interim lung cancer screening carry more than twice the risk of nodules present at the first scan. Get the rest of the story by clicking here.
Also, researchers from New York City presented their work in which FDG-PET/CT discovered significantly more unsuspected distant metastases in patients with newly diagnosed stage III invasive ductal cancer than in those with stage III invasive lobular cancer. The findings suggest that guidelines for staging breast cancer might need to be revised. Learn more by clicking here.

![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).

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)
