Synopsis

Keywords: Physics & Engineering: Physics, Image acquisition: Artefacts

Image artifacts are common in MR imaging due to system imperfections, physiological considerations,
and imaging parameter selection. In this session, we will view common artifacts that would be encountered in clinical MRI, and discuss how they may manifest at different field strengths, as well as in low-cost portable MR systems.

At the end of this session, an audience member should be able to identify common image artifacts, and be able to reason about which hardware component: main magnetic field, gradient, receive coil, or RF transmit, is the most likely contributor.
