Due to SNR constraints, current “bright‐blood” 3D coronary MRA approaches still suffer from limited spatial resolution when compared to conventional x‐ray coronary angiography. Recent 2D fast spin‐echo black‐blood techniques maximize signal for coronary MRA at no loss in image spatial resolution. This suggests that the extension of black‐blood coronary MRA with a 3D imaging technique would allow for a further signal increase, which may be traded for an improved spatial resolution. Therefore, a dual‐inversion 3D fast spin‐echo imaging sequence and real‐time navigator technology were combined for high‐resolution free‐breathing black‐blood coronary MRA. In‐plane image resolution below 400 μm was obtained. Magn Reson Med 45:206–211, 2001. © 2001 Wiley‐Liss, Inc.
