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.

Causes

electromagnetic spikes by gradient coils
fluctuating power supply
RF pulse discrepancies

Differential diagnosis

zipper artifact
- perpendicular to the frequency encoding direction
- less uniform
