Cat videos, daredevils, style mavens: You'll find them all on YouTube. But what does the wildly popular video site have to say about radiation safety and risks?A lot, it turns out, though much of it is very bad, according to fifth-year radiology resident and YouTube researcher Dr. Kedar Patil from McGill University in Montreal.
In this moderated poster session, Patil will discuss what his group found that "pertains to the use of YouTube to educate the public about radiation risks, while also highlighting the use of this social media to promote the radiology profession and increase its visibility in healthcare," he told AuntMinnie.com.
Patil and colleagues aimed to analyze the quality of YouTube videos about diagnostic imaging, radiation risks, and mammography using a "systematic semiquantitative cross-sectional analysis," the session abstract states.
Among the hundreds of videos they found searching keywords such as "CT scan" and "radiation risk," almost one-fourth were of poor quality, while others were surprisingly good. Find out more at this moderated poster series on health policy and research.
![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)
