zebra stripe sign
Zebra stripes/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
- Zero-fill artifact
- Spike in k-space
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 .
It therefore seems prudent to use "zebra" with a term like "stripes" rather than "artifacts".
