Happy to share our latest research on sustainable radiology hot off the press in @radiology_rsna 🌎🩻 doi.org/10.1148/radiol.24162… We found that short-term exposures to higher ambient temperature and worse PM2.5 air pollution are associated with increased medical imaging utilization

🎙️ How much can the air we breathe affect heart health?    @rnicola04 and @KateHanneman discuss the link between long-term air pollution exposure and coronary atherosclerosis, and what cardiac CT can reveal about cardiovascular risk. 👇

Toronto’s air quality is currently among the worst in the world due to wildfire smoke. Air pollution isn’t just a respiratory issue. It also affects the heart. Children and older adults are at increased risk. On days like today, limit outdoor activity and keep windows closed.
Wildfire smoke is affecting air quality across Toronto. People with heart or lung conditions, older adults and young children may be more affected. If you experience severe symptoms or trouble breathing, seek medical attention. Check current conditions: bit.ly/4w87svW

Wonderful trip to San Diego for #SCCT2026 ☀️ A highlight was “Cardiac CT at a Crossroads,” exploring how access, equity, patient experience, workforce well-being, sustainability, and global collaboration will shape the field. Great science, discussion, and community! @Heart_SCCT

“Burnout is not a personal failure,” says @ChinnaiyanMD at #SCCT2026. The more we try to hide it, the more pervasive it becomes and the less likely systems are to change. Burnout is not a wellness problem, but a “workforce problem,” she adds.

Up to 50% of imaging programs in the US leave scanners on overnight in a ready-to-scan mode. By focusing on powering down, the field can have a significantly lower environmental footprint, argues @KateHanneman at #SCCT2026

In patients with HCM, can machine learning plus cardiac #MRI tell us not just who is at risk, but what kind of risk? We tested exactly that in 604 patients. New publication hot off the press @RadiologyCTI @RSNA @HayleyAMcKee 📄pubs.rsna.org/doi/10.1148/ry…

A machine learning model trained on 33 variables (clinical, genetic, and imaging) in 604 HCM patients performed comparably to the ESC risk score (C-index 0.75). #WhyCMR features were key predictors, including apical aneurysm, LV volumes, extensive LGE and T1 mapping ⬇️

Different outcomes (MACE, NSVT, and AF) had distinct top predictors, emphasizing phenotype-specific risk and the value of #WhyCMR in #HCM risk stratification. With thanks to @HunainShiwani for the thoughtful accompanying editorial 📄 pubs.rsna.org/doi/10.1148/ry…
