The magnetic memory of credit and similar cards, as well as magnetic devices such as tapes, will be erased by MR magnets.

Quick Overview
Please note that there are different common names for this artifact.

This artifact appears as a herringbone pattern scattered over the whole image in any direction only on one slice or on multiple slices. The causes of this are many and various, like e.g. electromagnetic spikes created by the gradients, electronic equipment inside the MR procedure room, or fluctuating AC current.

Sometimes it is sufficient to change flickering light bulbs. If the problem increases or keeps on existing, it should be addressed by a service representative.

A mathematical method for evaluating whether two features, i.e., ROI measurements obtained from a temporal series of images, share common characteristics and are therefore correlated.

Energy transfer to nearby slices by the RF pulse.

See Crosstalk Artifact.

RF coil pair arranged with their magnetic fields at right angles to each other in such a way as to minimize their mutual magnetic interaction.
