Native T1 relaxation time of the liver differentiates IDCM patients with and without heart failure more accurately than established functional parameters such as LV volume, LVEF, and LV strain.
Observational
Does native T1 relaxation time of the liver improve the differentiation of congestive heart failure in patients with IDCM compared to established functional parameters?
Hepatic native T1 relaxation time on cardiac MRI is an accurate noninvasive marker for congestive heart failure in IDCM patients, outperforming standard LV functional parameters.
Native T1 relaxation time of liver is an easily accessible and accurate noninvasive imaging marker of congestive heart failure in patients with IDCM. It can be measured on standard short-axis cardiac MRI T1-weighted maps and facilitates differentiating patients with IDCM with from those without heart failure more accurately than established functional parameters, such as LV volume, LVEF, and LV strain.
Huber et al. (2020) conducted an observational in Idiopathic Dilated Cardiomyopathy (IDCM). Hepatic T1-weighted MRI mapping vs. Established functional parameters (LV volume, LVEF, LV strain) was evaluated on Differentiation of IDCM with and without congestive heart failure. Native T1 relaxation time of the liver differentiates IDCM patients with and without heart failure more accurately than established functional parameters such as LV volume, LVEF, and LV strain.
