title: [Artifacts in magnetic resonance angiography].
abstract: Magnetic resonance angiography (MRA) has become a major tool in the management of vascular diseases. However, many artifacts that may lead to misinterpretations are encountered with this imaging modality. The purpose of this paper was to enumerate, explain and illustrate each kind of artifact encountered with "time of flight" or "phase contrast" imaging methods. For each artifact, we tried to provide one or several techniques to minimize its consequences.
