MRI Artifacts Magnetic resonance imaging (MRI) has become more and more frequently used in medical imaging diagnosis in the recent years. Radiologists and technicians working at these systems are relatively often confronted with image artifacts related to the radiowave with strong magnets in the scanner. Numerous artifacts are associated with MR scanning.1-4 With an understanding of their cause, many may be corrected, minimized, or avoided, either at the source before data acquisition or at the reconstruction stage after data acquisition. This requires familiarity with the scanner design, the theory of operation and image acquisition. Therefore, this article presents the most relevant artifacts occuring in MRI, providing physical background on the formation of artifacts and suggesting strategies to reduce or avoid these artifacts. Motion-related; para-magnetic; phase wrap; frequency; susceptibility; clipping; chemical shift and zebra artifacts are the most frequent MRI artifacts.
