Position Statement on the Use of Multiparametric Mapping for Advanced Tissue Characterization by Cardiovascular Magnetic Resonance – 2026

Introduction

Cardiovascular diseases continue to be the leading cause of morbidity and mortality in Brazil, having a significant impact on both public health and socioeconomic costs. Among these conditions, cardiomyopathies – both ischemic and non-ischemic – stand out for their high prevalence, etiological diversity, and diagnostic complexity. Early and accurate recognition of these diseases is essential for guiding

appropriate treatment interventions, improving prognosis, and reducing adverse outcomes.

In this context, cardiac magnetic resonance (CMR) imaging has established itself as one of the primary tools for evaluating patients with cardiomyopathies. In addition to providing detailed anatomical and functional information, CMR plays an increasingly important role as a multiparametric imaging method, allowing for the noninvasive, highly accurate characterization of myocardial tissue. International and

national guidelines highlight the importance of CMR and computed tomography (CT) in the diagnosis of ischemic and non-ischemic cardiomyopathies, as well as congenital heart diseases, reinforcing the relevance of these methods in contemporary clinical practice.
