In this review, the authors examine recent advancements in noninvasive cardiac imaging, focusing on cardiac CT, MRI, and PET, reviewing key publications from imaging and multidisciplinary journals from 2023. The authors discuss the increasing adoption of photon-counting CT and its applications in coronary and structural imaging, and explore various aspects of plaque and functional assessment, emphasizing their clinical implications. Radiation exposure analysis from the SCOT-HEART (Scottish Computed Tomography of the Heart) trial is also discussed. The authors highlight the integration of artificial intelligence applications in cardiac imaging. Three-year follow-up data from the ADVANCE Registry are described, showcasing the potential of using artificial intelligence to improve diagnostic accuracy and patient outcomes in cardiovascular care. The authors explore the latest studies evaluating different cardiomyopathies using cardiac MRI. Radiologists' growing understanding of the brain-heart axis is presented through discussion of several studies. The authors also discuss the prognostic advantages of MRI over PET in patients with cardiac sarcoidosis. Finally, the authors outline society statements and guidelines from 2023 that are pertinent to cardiac imaging, offering a comprehensive review of current trends and applications in noninvasive imaging modalities.
