Eddy currents are a common source of artifacts in Spiral MRI. Eddy currents that effect the k-space trajectory are often the focus of eddy current correction. However, the spatially uniform but time-varying B0 eddy currents can also be a subtle but important source of artifacts in spiral images. This work demonstrates the improvement in image quality that can result from measuring and correcting the phase produced by B0 eddy currents in spiral MRI.
