Dark-Blood Late Gadolinium Enhancement (DB-LGE) sequence has been recently introduced to suppress the blood signal in order to enhance the contrast between blood and scar. However, it is difficult to distinguish scar from fat as both appear bright in DB-LGE images. In this study, we present a DB-LGE sequence that allows quantification of scar and fat volume in the heart in a single imaging sequence. Numerical simulation, phantom and in-vivo scans were performed to evaluate the proposed sequence.
