Synopsis

Keywords: Image acquisition: Artefacts

This session will provide an overview of common image artifacts observed in MRI. Artifacts will be sorted into hardware-related artifacts (in general, ones that can be reproduced in phantoms), and physiological artifacts (ones that can only be observed in vivo). Emphasis will be placed on analyzing raw k-space and coil data to promote an in-depth signal-based understanding. By the end of this session, an attendee should be able to identify what is, and what is not an artifact, and narrow-down candidate causes of the artifact.
