Huber AT, Razakamanantsoa L, Lamy J, et al. - This study was carried out to investigate the hypothesis that individuals with idiopathic dilated cardiomyopathy (IDCM) and heart failure have raised liver T1 relaxation times at MRI owing to congestion compared with the T1 relaxation times in individuals with IDCM without heart failure and healthy control participants. Researchers performed a retrospective cross-sectional study including a total of 55 individuals (33 men, 22 women; mean age, 47 ± 15 years) who underwent cardiac MRI: 20 healthy control subjects and 35 consecutively registered patients with IDCM. In individuals with IDCM, native T1 relaxation time of liver was found to be an easily accessible and accurate noninvasive imaging marker of congestive heart failure. It can be assessed on standard short-axis cardiac MRI T1-weighted maps and support differentiating individuals with IDCM with from those without heart failure more accurately than developed functional parameters, such as left ventricular (LV) volume, left ventricular ejection fraction and LV strain.
