[Artifacts induced by dental reconstruction materials: the case of titanium].
MRI is becoming an important tool of examination of the head and neck. However, certain dental alloys cause artifacts characterized by a loss of signal surrounded by bright line and sometimes distortions. In our work, we studied artifacts caused by Titanium, metallic biomaterial used for oral implantology. Therefore, 2 experimental were investigated in a 1.5 T MR unit, with 2 sequences commonly used (SE, GRE). The investigation showed minor artefacts, without distortions. In order to minimize these "ghost images", the Titanium and its alloys should be an alternative.
