Dr. Lauren Kim speaks with first author Dr. Andrew Hernandez about his study which comprehensively quantified energy consumption in MRI, CT, and PET/CT imaging suites by measuring the energy utilization of main power, HVAC, and chilled water subsystems. The study showed that HVAC and chilled water subsystems contribute substantially to total energy consumption, that energy efficiency increases with increasing daily scanning volume, and that a substantial portion of energy consumption occurs during non-operating hours.

Host Dr. Reni Butler sits down with Dr. Connie Lehman to discuss groundbreaking research on how AI-generated breast cancer risk scores change over time and what those changes may reveal about a woman's future cancer risk. Together, they explore the promise of longitudinal imaging biomarkers, personalized screening strategies, and how artificial intelligence could transform breast cancer detection and prevention.

Dr. Refky Nicola welcomes back Dr. Kate Hanneman to discuss new research examining the link between long-term air pollution exposure and coronary atherosclerosis detected on cardiac CT. Together, they explore key findings on plaque burden, sex-specific differences, cumulative exposure risks, and the growing cardiovascular implications of wildfire smoke.

Dr. Lauren Kim and first author Dr. Daniel Marinescu discuss this study comprised of approximately 1,500 patients which determines the relative importance of specific CT imaging features used to distinguish radiologic patterns in fibrotic interstitial lung disease. This study identifies areas of substantial incongruence between radiologist-assigned ILD patterns and current clinical diagnostic guideline definitions, incongruencies which in turn may help refine and standardize future diagnostic criteria.

Host Dr. Celina Nahyun Jo sits down with Dr. Perry Pickhardt to explore how opportunistic CT screening is transforming routine imaging into a powerful tool for cardiometabolic risk assessment, bone health evaluation, liver disease detection, and body composition analysis. Together, they discuss the role of explainable AI, the future of CT-based biologic age, and why value-added imaging has the potential to reshape preventive care.
