Can cardiac magnetic resonance (CMR) enlighten us in cardiac transplant rejection? Do myocardial patterns matter for heart failure? What can imaging phenotypes tell us about the stages of Fabry's disease?

A special focus issue of JACC: Cardiovascular Imaging dedicated to the latest findings surrounding CMR in heart failure examines answers to these important questions and more.

In the Editor's Page, Multiparametric CMR in Cardiomyopathies: Beyond Diagnosis and Toward Prognosis, Editor-in-Chief Y. Chandrashekhar, MD, DM, FACC, and Executive Editor Christopher M. Kramer, MD, FACC, discuss the major inroads CMR has made in differentiating among the underlying causes of heart failure.

The full issue, which contains eight original research papers with accompanying editorials, is available at Imaging.OnlineJACC.org.
