Cardiac CT and MRI: A Comprehensive Review of Current Clinical Guidelines

Abstract

Medical imaging plays a pivotal role in cardiovascular care by enabling accurate, non-invasive diagnosis, risk stratification, and
treatment planning. Cardiac computed tomography (CT) and cardiac magnetic resonance imaging (MRI) have revolutionized
cardiovascular diagnostics by providing detailed insights into cardiac anatomy, myocardial function, and coronary vascular
health. MRI offers excellent soft tissue characterization without ionizing radiation, whereas CT provides rapid, high-resolution
coronary artery visualization and quantification of calcified plaques. Recent advances, including artificial intelligence (AI) and
hybrid imaging technologies, have improved diagnostic accuracy, workflow efficiency, and patient safety. Despite these
technological advances, coronary artery disease (CAD) remains the leading cause of mortality globally, emphasizing the need
for precise and standardized imaging practices.
