Zebra stripes, a.k.a. zebra artifacts, appear as alternating bright and dark bands in a MRI image. The term has been used to describe several different kind of artifacts causing some confusion.
Artifacts that have been described as a zebra artifact include the following:
- moire fringes 1,2
- spike in k-space
- zero-fill artifact
Zebra stripes have been described associated with susceptibility artifacts.
In CT there is also a zebra artifact from 3D reconstructions and a zebra sign from hemorrhage in the cerebellar sulci, and potentially-confusingly a zebra stripe sign in the bones of those treated with cyclical bisphosphonates for osteogenesis imperfecta 3,4.
It therefore seems prudent to use "zebra" with a term like "stripes" rather than "artifacts".
