The T2-prepared BOOST sequence was recently introduced for simultaneous post-contrast 3D whole-heart bright-blood coronary angiography and black-blood late gadolinium enhancement (LGE) imaging. This sequence enables simultaneous visualization of cardiac anatomy, the coronary arteries and scar tissue. However, high-resolution fully-sampled BOOST requires long acquisition times of ~20min. Here, we propose to accelerate the T2-prepared BOOST sequence and achieve high spatial resolution 3D whole-heart black-blood LGE and coronary MR angiography. This is accomplished by extending XD-ORCCA, a highly efficient respiratory-resolved motion-corrected framework, to BOOST imaging. The proposed framework enables simultaneous black-blood LGE and bright-blood coronary angiography within clinically feasible acquisition times.
