ABSTRACT
Objective:
To develop titanium posted keeper removable magnetic attachment and to decrease its influence on magnetic resonance imaging(MRI).Methods:
Pre fabricated soft magnetic alloy pin cap keeper(PSAPK), casting non precious alloycoping keeper(CNPAK), casting precious alloy coping keeper(CPACK), titanium post keeper(TPK) and titanium post(TP) were prepared and applied on the maxilla of a volunteer, MRI was taken and measured.Results:
①The attachments producing artifacts in MRI from the biggest to the smallest were listed in following rank PSAPK, CNPAK, CPACK, TPK and TP. ②After removing the keeper from titanium post keeper, the post had no artifact on MRI. ③The artifact was the smallest taken with SE sequence.Conclusion:
Titanium post keeper is an effective way to solve the artifact problem and will bring benefits to the patients who need MRI examination of head.
