The acquisition of complete three‐dimensional (3D), segmented gradient‐echo data sets to visualize the coronary arteries can be both time consuming and sensitive to motion, even with use of multiple breath‐holding or respiratory gating. An alternate hybrid approach is demonstrated here, in which real‐time interactive imaging is first used to locate an optimal oblique coronary scan plane. Then, a limited number of contiguous slices are acquired around that plane within a breath‐hold with use of two‐dimensional (2D) segmented gradient‐echo imaging. Dual inversion nulling is used to suppress fat and myocardium. Finally, if needed, a limited reformat of the data is pelformed to produce images from relatively long sections of the coronaries. This approach yields relatively rapid visualization of portions of the coronary tree. Several different methods are compared for interactively moving the scan plane.
