Název v původním jazyce

Magnetic susceptibility and electrical conductivity of metallic dental materials and their impact on MR imaging artifacts

Popis výsledku v původním jazyce

The aim of this study was to test the hypothesis that dental materials vary significantly in MR-relevant material parameters?magnetic susceptibility and electrical conductivity, and that knowledge of these parameters may be used to estimate the quality of MR imaging in the presence of devices made of such materials. For typical dental devices, magnetic susceptibility differences were found of little clinical importance for diagnostic SE/GE imaging of the neck and brain, but significant for orofacial imaging. Short-TE GE imaging has been found possible even in very close distances from dental devices made of amalgams, precious alloys and titanium alloys. Nickel?chromium and cobalt?chromium artifacts were found still acceptable, but large restorations ofaluminum bronzes may preclude imaging of the orofacial region. The influence of electrical conductivity on the artifact size was found negligible.
