Synopsis
Keywords: Image acquisition: Motion correction, Cross-organ: Pediatric
The goal of this educational talk is to provide the participants with a better understanding of pediatric MRI scans. By the end of the session, attendees should have a clear understanding of current imaging practices for younger children, as well as novel techniques for measuring motion using external trackers and navigators. The session will also cover how real-time motion measurements can be used to improve the success rate of pediatric MRI scans. Finally, the pros and cons of prospective versus retrospective corrections will be discussed, providing attendees with a comprehensive understanding of the options available for improving pediatric MRI scans.
