For MRI applications care must be taken to limit the amount of magnetically susceptible metal inside the MRI scanner. Particularly, if any screws are included for implant fixation, the use of ceramic material will limit the distortion caused to the MRI scan.

Therefore it is recommended to fix implants with ceramic screws. Thomas RECORDING offers a set of 5 different ceramic screws made of zirconium oxide. These screws were developed and firstly used by Prof. Dr. Nikos Logothetis at the Max Planck Institute for Biological Cybernetics in Tuebingen, Germany [1]. The ceramic screws were tested on MR quality control phantoms and were found to have no effects on the homogeneity of the B0 field of the magnet [1]. In addition the material was chosen to be tissue compatible and are surface roughened to optimize the bone and skin implant interface [1].

Thomas RECORDING is proud to be the worldwide sole distributor of these high quality ceramic screws. Our ceramic screws are used by leading neuroscientists all over the world (see a selection of related publications at the end of this page).
