Popis: A solid, stable material that can be easily cut into unique, identifiable shapes was compared with other localization markers used in magnetic resonance imaging to determine relaxation characteristics and chemical shift. The solid marker and the conventional oil-based markers caused substantial chemical shift artifacts and so should never be used when high levels of spatial accuracy are necessary, such as in stereotaxy. Although it had the lowest T2 of all the substances tested, the solid marker was useful in identifying structures when different coils, sequences, and fields of view were used.
