I am using a Bruker 600M solid-state NMR spectrometer with a Micro 2.5 microimaging system.The diameter of 1H coil is 30mm.I found that MRI artifacts are quite severe when metal is present. As shown in the image, the gray and brown areas represent the container, the pink represents metallic copper, and the blue represents water. When using FLASH and RARE pulses for imaging, there are significant artifacts in the image. I suspect this is due to the large difference in paramagnetism between copper and water. What methods are generally used to eliminate these types of artifacts?
