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.

Dr. Linda Chu speaks with Dr. Eddy Zandee and Dr. Kirk Davis about multidisciplinary expert consensus recommendations aimed at reducing the use of low yield radiographs and improving imaging appropriateness across healthcare settings. They explore which common radiographic exams may offer limited clinical value, when CT or MRI may be more appropriate, and how education and workflow changes can help optimize imaging utilization.

Dr. Ashwin Singh Parihar sits down with Dr. Louise Emmett to discuss how post-therapy Lutetium-177 PSMA SPECT/CT may help predict overall survival in patients with metastatic castration resistant prostate cancer and shape future treatment decisions. Drawing from the ENZA-p trial run by ANZUP cancer trials group, they explore quantitative imaging, treatment response assessment, adaptive dosing strategies, and the growing role of theranostics in precision oncology.
