Dr. Celina Nahyun Jo talks with Dr. Mahla Radmard about how NEXUS and the Canadian C‑Spine Rule shape cervical spine imaging decisions in trauma patients. Together they explore new research that questions long‑standing imaging practices and highlights opportunities to improve value safety and accuracy in patient care.

Dr. Refky Nicola speaks with Dr. Atul Shinagare about his team's research showing that incidental adnexal lesions on single‑phase CT are often difficult for radiologists to classify consistently, with only certain classic lesions yielding strong agreement. Their conversation underscores the limitations of CT compared with ultrasound or MRI and reinforces that most incidental adnexal findings are benign, though many still require additional imaging for clarification.

Dr. Ashwin Parihar speaking with Drs. Sungmin Woo and Alberto Vargas about why standardized PSMA PET scoring systems—such as PSMA‑RADS and PROMISE—are becoming essential for consistent interpretation, communication, and treatment planning in prostate cancer. They explore the evidence behind these frameworks, current barriers to adoption, and how future harmonization efforts like the SPARC Initiative may shape the evolution of PSMA PET reporting.

Dr. Lauren Kim speaks with Adarsh Mallepally and Dr. Cory Trankle about their large-scale retrospective study of nearly 4 million patients examining the risk of nephrogenic systemic fibrosis after gadolinium-based contrast administration in those with advanced renal dysfunction. They discuss how modern group 2 and macrocyclic agents were associated with an exceedingly low incidence of NSF, offering important reassurance for evidence-based contrast use and evolving clinical practice.

Dr. Linda Chu speaks with Dr. Kavitha Chinnaiyan and Dr. Jonathon Leipsic about why 2026 marks an inflection point for coronary CT, from AI-enabled plaque quantification to FFR-CT and evolving guideline support for CT-first evaluation of suspected coronary artery disease. They explore how advanced imaging tools are reshaping risk assessment, personalizing prevention and revascularization decisions, and strengthening collaboration between radiology and cardiology while highlighting the need for validation, standardization, and equitable access.
