Week in review: Cutting CO2 emissions | AI and imaging safety warnings | Tracking ground-glass nodules

Dear AuntMinnie Member,

Our most popular articles this week centered around a particular theme: sustainability and reduction of carbon emissions in radiology. Our top story outlined how the use of solar energy could dramatically cut MRI and CT emissions, while our second explored the environmental impact of x-ray and fluoroscopy. In third and fourth place? A report on how "circular" business models for replacing MRI scanners can reduce costs and waste and an article about what factors contribute most to ultrasound's carbon footprint.

Readers also showed interest in coverage of a study that reported that AI chatbots aren't necessarily giving patients safety warnings for imaging exams, an article on research that found that surveillance of ground-glass nodules on CT appears sufficient compared with surgery, and a story regarding a study that explained how diffusion MRI has revealed a new pattern underlying Alzheimer's disease.

See below for the full list of our top stories of the week: 

1. Use of solar energy could cut MRI, CT carbon emissions by 70% and 40%
2. What’s the environmental impact of x-ray and fluoroscopy?
3. 'Circular' business models for replacing MRI scanners reduce costs, waste
4. Linens, disposable items make up most of ultrasound's carbon footprint
5. AI chatbots aren't giving patients safety warnings for imaging exams
6. Surveillance of ground-glass nodules found on CT appears sufficient
7. Diffusion MRI reveals new pattern underlying Alzheimer's disease
8. Lobular breast cancer incidence rising
9. AI fracture detection tools tested head-to-head
10. AI improves interreader CAD-RADS agreement on CCTA
11. World Trade Center attacks boosted lung cancer incidence in responders nearly 3-fold
12. GLP-1 drugs may confound PET/CT imaging findings
13. U Penn physicist's family donates what could be earliest x-ray images
14. Komen: Fewer Black women are dying from breast cancer
