The accuracy of cardiac T2 mapping in small structures, such as the subendocardium, right ventricle, and left atrium, is impaired by the partial-voluming effect between myocardium and blood. In this work, we propose a dark-blood T2 mapping method that nulls the blood prior to the T2 quantification, so that partial-voluming is reduced and T2 estimation accuracy in these small structures is improved. Both conventional and the proposed dark-blood T2 mapping methods were performed in healthy subjects. The results demonstrated the potential of dark-blood T2 mapping to improve the clinical assessment of the subendocardium, right ventricle, and left atrium.
