Photon-counting detector computed tomography : Paradigm shift in cardiac CT imaging

Background: The introduction of photon-counting detector computed tomography (PCD-CT) heralds a new generation of cardiac imaging. Objectives: This review discusses the current scientific literature to determine the incremental value of PCD-CT in cardiac imaging. Methods: Discussion of currently available literature regarding cardiac PCD-CT from a radiological perspective. Results: Since its market introduction in 2021, numerous studies have explored the advantages of this new technology in the field of cardiac imaging, including improved image quality through superior spatial resolution, a higher contrast-to-noise ratio, reduced artifacts, and lower radiation dose. Conclusion: While preliminary studies have been promising, it remains to be seen how the advantages of PCD-CT will affect clinical guidelines for cardiac CT.
