Abstract: Foldover artifacts arise when the same imaging frequency occurs both at a desired location within a slice and at another location within the sensitive region of the radiofrequency (RF) coil. Foldover artifacts can be caused by nonlinearity in the gradient system and by inhomogeneity in B<INF>0</INF>. This study investigates an approach in which an extra RF receiver coil and a postprocessing method are used to identify and remove foldover artifacts. J. Magn. Reson.
