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 Bo. This study investigates an approach in which an extra RF receiver coil and a postprocessing method are used to identify and remove foldover artifacts. (C) 2000 Wiley-Liss, Inc.</p
