Myocardial T 1 imaging is an emerging tool for tissue characterization, however its use has been limited to the left ventricle. We developed a novel MRI sequence (IDEAL-T 1 ) that combines fat-water separation and T 1 imaging, with and without black blood preparation, for myocardial T 1 imaging, including the right ventricle. We evaluated IDEAL-T 1 using Bloch equation simulations, phantom, and in vivo studies. IDEAL-T 1 , with and without dark blood preparation, showed good agreement in phantoms and in vivo. The dark blood preparation allowed for right ventricular analysis in all, however showed lower T 1 values than bright blood images likely due to perfusion effects.
