Overview
MRI is affected by multiple sources of artifacts, which can complicate the clinical and research use of reconstructed images. This educational session will describe two central sources of artifacts in MRI: physiological motion and magnetic susceptibility effects. For each of these effects, this session will provide a clinical overview of the impact of artifacts in practice, followed by a technical description of existing and emerging mitigation methods.
Target Audience
Scientists, engineers, and clinicians interested in the connection between common MRI artifacts and technical solutions.
Educational Objectives
As a result of attending this course, participants should be able to:
- Describe the MR artifacts arising from motion and susceptibility;
- Describe and distinguish methods to mitigate motion artifacts; and
- Describe and distinguish methods to mitigate susceptibility-induced effects.
| 08:00 |  | Motion Artifacts in Clinical Practice Su-zhen Dong Keywords: Education Committee: Clinical MRI, Image acquisition: Artefacts This talk will cover MRI motion artifacts in clinical practice of fetuses and children, including the understanding of the influence of MRI examination of fetuses and children, and strategies to reduce or minimize the impact of motion artifacts on image diagnostic quality. The strategies to reduce or minimize the impact of motion artifacts will include exam preparation with MRI simulation, optimization of MRI environment, role of child life specialists, noise-reduction, optimization of MRI protocol design, the application of fast sequences and fast scanning technology, and motion-compensation and retrospective motion correction techniques. |
