Overview
Physiological and patient motion during an MRI exam is an ongoing issue that radiographers must contend with daily. The purpose of this session is to provide the audience with a review of existing retrospective and prospective motion correction algorithms and pulse sequences used in clinical body MRI. Additionally, advanced hardware and techniques to detect, characterize, and model motion will be discussed.

Target Audience
medical physicists, radiologists and other healthcare professionals interested in motion correction.

Educational Objectives
As a result of attending this course, participants should be able to:
• Identify the common causes of motion-induced artifacts in body MRI;
• List the common approaches employed to mitigate motion in clinical body MRI; and
• Describe advanced algorithms and hardware in research to target motion in body MRI.

07:00		Basic to Advanced Motion Correction Methods in Body MRI: A Clinical Perspective (How Do I Do It) View Presentation Video Hersh Chandarana Impact: This presentation will discuss the limitations of abdominopelvic MRI exam in patients who cannot adequately hold their breath, and various state of the art methods and tools used in clinical practice to manage motion. Subsequently we will highlight limitations of these methods and unmet need.
07:15		Commercially Available Motion Mitigation Techniques for Abdominal & Body MRI Nathan Artz
07:30		AI-Driven Motion Correction in Body MRI View Presentation Video Ricardo Otazo Impact: The learning capabilities of AI can improve the performance of motion correction in body MRI.
07:45		Model Based Motion Correction for Body MRI: Challenges & Opportunities View Presentation Video Melissa Haskell Impact: This talk will discuss the challenges of motion correction in body MRI from an MR physics perspective, focusing on model based image reconstruction (MBIR) and characteristics of body MRI that can be leveraged when using MBIR.
