Variable density (VD) spiral trajectories are an efficient method for data acquisition and may be advantageous for first pass myocardial perfusion imaging. By only partially correcting the variable density, k-space is weighted by a smooth function which reduces Gibbs Ringing. This strategy is employed to further reduce dark-rim artifacts for spiral myocardial perfusion imaging.
