The invention includes a technique for efficient multi-slice image
acquisition with black blood contrast in cardiac imaging such that MR
data is acquired in each R-R interval of a cardiac cycle. The technique
includes applying a non-selective inversion pulse, followed by a
re-inversion pulse that is slice-selective over a region encompassing a
plurality of slice selections. The inversion and re-inversion pulses are
applied in each R-R interval. Execution of a series of RF excitation
pulses in each R-R interval is timed such that signal from blood is near
a null point before data acquisition.
