The volume of magnetic resonance imaging (MRI) studies read by radiologists is continuing to increase year after year. The art of interpreting MRI, however, is complicated by the many artifacts that occur within the modality. These artifacts are often a source of confusion and frustration for the interpreting radiologist, especially during training. As artifacts can often be misinterpreted as pathology or can limit the diagnostic value of a study by obscuring the findings, it is imperative that radiologists understand both the underlying cause and how to rectify these artifacts.

Educational Goals / Teaching Points
Reviewing key imaging findings of a wide range of MRI artifacts. Explaining the underlying causes and physics behind these artifacts. Providing viable solutions to fixing MRI artifacts when encountered. Covering high-yield facts about each artifact that may be relevant to radiology boards and recertifying exams. Presenting this information in an interactive format to facilitate active learning and retention.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The exhibit will begin with a review of the relevant basics of MRI physics. Each artifact will then be introduced with a short self-exam where the viewer will be asked to identify the artifact present on the image. The following slides will then reveal the answer and expand upon the causes, solutions, and relevant trivia pertaining to the artifact in question.

With MRI studies occupying an ever-increasing percentage of the practicing radiologist’s workflow, it is imperative to be familiar with the wide range of artifacts present within the modality. By the end of this presentation, the topic of MRI artifacts should be less intimidating, and the viewer should be comfortable with not only identifying the artifact, but also implementing solutions to rectify them in their daily practice.
