Artifacts: When Things Go Wrong, It’s Not Necessarily All Bad

  • Michael L. Lipton

Abstract

Artifacts are common in all diagnostic imaging modalities, but nowhere is their study as much a field unto itself as in MRI. This is for a very good reason: MRI artifacts often convey important diagnostic information. They are not just nuisances. In the context of our study of MRI, artifacts are also important, an opportunity if you will, because they drive home many of the physical concepts we have been discussing. Finally, of course, artifacts can certainly be the first sign of trouble. Recognizing them allows the informed user to correctly identify the likely source(s) of the problem and even to determine if a user modification or a service call is necessary.
