Self-consistent parallel imaging (SPIRiT) is a self-calibrated, iterative parallel imaging technique that is not restricted by a particular k-space sampling pattern. 3D SPIRiT takes advantage of the 3D arrangement of a modern receive array to further improve image quality. Although SPIRiT was shown to yield higher image quality than does GRAPPA, especially at acceleration factors higher than 2, its signal-to-noise behavior has not been rigorously studied. In this study we investigate the image quality behavior of 3D SPIRiT and determine the optimal condition for best image quality.
