SCCT Debate: Is Photon-Counting CT Ready to Replace Conventional CT for Pre-TAVR CAD Evaluation?

At SCCT, experts debated whether photon-counting CT (PCD-CT) should be the new standard for coronary artery disease assessment before TAVR. Proponents highlighted its superior spatial resolution and reduced blooming artifacts compared to conventional CT. No new patient-level dat…

• The SCCT session was a pro/con debate, not a presentation of original research; no sample size or statistical results were reported.
• PCD-CT’s technical advantages—higher resolution, lower noise, and spectral capabilities—may improve stenosis grading and reduce nondiagnostic scans, but availability and cost remain barriers.
