Herringbone artifact

Last revised by Assoc Prof Frank Gaillard on 02 Dec 2020

Herringbone artifact, also known as spike artifact, crisscross artifact, or corduroy artifact, is an MRI artifact related to one or few aberrant data point(s) in k-space. In image space, the regularly spaced stripes resemble the appearance of a fabric with a herringbone pattern. The artifact covers the entire image in a single slice or multiple slices.
