摘要：
The purpose of this study was to evaluate the MR compatibility of ceramic instruments. Mine different ceramic instruments were tested with respect to ferromagnetism, heating, and artifacts using previously described techniques. There was no magnetic field attraction, temperature increases were less than or equal to.1 degrees C, and artifacts involved a signal void similar to the size and shape of each instrument, The ceramic instruments were demonstrated to be compatible with MR imaging and acceptable for use during intraprocedural MR imaging.
