Motion Artifacts in Clinical Practice
1Radiology, Shanghai Children's Medical Center, School of Medicine, Shanghai Jiao Tong University, Shanghai, China
Synopsis
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.Abstract
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 (radial k-space sampling and compressed sensing), and motion-compensation and retrospective motion correction techniques. In addition, insights into future developments and emerging techniques of motion compensation including deep learning/artificial intelligence, will also be introduced.Acknowledgements
