Bright- and black-blood MRI sequences provide complementary diagnostic information in patients with congenital heart disease (CHD). Typically, contrast agent administration is needed to depict structures such as the pulmonary veins or regions of disturbed blood flow. However, contrast-enhanced imaging is not ideal for regular screening, while the acquisition of bright- and black-blood sequences in a sequential fashion remains sub-optimal. Here we propose a motion-compensated 3D whole-heart sequence that provides co-registered bright- and black-blood volumes without the need for contrast agent administration. The sequence was tested in patients with CHD and showed high-quality delineation of both arterial and venous structures.
