Abstract:
In this paper,to evaluate the existence and extent of MRI artifacts caused by frequently used metallic dental materials and to compare the influence of different MRI sequences on artifacts. The artifact of Au-Pt-Pd alloy crown were the smallest and Au-Ag-Pd alloy crown, pure Titanium crown were smaller. But the artifact of Ni-Gr alloy crown were the largest.With the same scan sequences, the different metal materials can make different effects on MRI images with the different scan sequences, the MRI artifact is not obvious caused by the same metal materials. Artifacts produced by oral metallic materials related closely to the type of the materials.The high quality MRI can be gained by choosing proper metallic materials.
