Zero fill artifact

Last revised by Andrew Murphy on 2 Apr 2020

Zero fill artifact is one of many MRI artifacts and is due to data in the K-space array missing or set to zero during scanning. The abrupt change from signal to no signal results in artifacts in the images showing alternating bands of shading and darkness, often in an oblique direction.

A spike in k-space as from an electrostatic spark is another artifact that causes oblique stripes.
