Cardiac CT for Aortic Stenosis: Novel Quantitative Techniques for Comprehensive Patient Assessment.

Abstract

In recent years, the landscape for the diagnosis and management of patients with aortic stenosis (AS) has rapidly changed, with a dramatic increase in therapeutic options and substantial advances in different imaging modalities. Multidetector CT (MDCT) has become an essential imaging tool for evaluating the feasibility of both surgical and interventional treatments for patients with severe AS. Novel MDCT imaging acquisition protocols, postprocessing tools, and technological advances offer not only detailed anatomic information for adequate procedural planning but also comprehensive quantitative evaluation of the myocardium for assessment of remodeling and function, both of which have prognostic and therapeutic implications. This review provides a comprehensive update on the role of novel MDCT quantitative techniques in the assessment of patients with severe AS. Keywords: CT, Cardiac, Valves, Aortic Stenosis © RSNA, 2025.
