Diagnosis of fibrofatty infiltration of the myocardium, a cardinal feature of Arrhythmogenic Right Ventricular Dysplasia (ARVD) until the advent of cardiac MR could only be diagnosed by myocardial biopsy or at autopsy. Cardiac Magnetic Resonance offers comprehensive depiction of the anatomy and function of the right ventricle, and because of he characteristic appearance of fat on MR images allows depiction of fat within the wall. Our aim was to investigate the feasibility of multi-echo Dixon technique for water fat separation during cardiac imaging at 3T compared to the standard approach of black-blood spin-echo imaging with and without fat suppression.
