Improved Motion Correction & Effective Free-Breathing Approaches
Combined Educational & Scientific Session

ORGANIZERS: Bernd Wintersperger, Jenny Keegan

Tuesday, 14 May 2019
513A-C  15:45 - 17:45 Moderators:  Andrew Scott, Matthias Stuber

Skill Level: Basic to Intermediate

Session Number: Tu-07

This session will review conventional and advanced approaches to cardiac and respiratory motion correction in cardiovascular MRI.

Target Audience
Clinicians and scientists wishing to understand how cardiac and respiratory motion can be corrected for, both on commercial clinical scanners and in research applications. 

Educational Objectives
As a result of attending this course, participants should be able to:
- Recognize how the heart moves with the respiratory and cardiac cycles
- Compare how the motion affects image quality for different sequences and different k-space paths. 
- Describe conventional methods of motion correction 
- Explain emerging highly advanced techniques that are highly efficient and may provide cardiac and/or respiratory motion-resolved imaging.


Motion of the Heart with the Respiratory & Cardiac Cycles: Conventional Approaches to Motion Correction
Leon Axel
Respiratory and cardiac motion can result in degradation of MR images. We review the basic aspects of these motions, and some standard means that can be used to monitor them and control their effects on imaging.

Motion of the Heart with the Respiratory & Cardiac Cycles: Advanced Motion Correction Techniques
Claudia Prieto
MRI acquisition is slow compared to physiological motion, thus the extensive cardiac- and respiratory- induced motion of the heart during the acquisition period can degrade image quality by introducing ghosting and/or blurring like motion artefacts. Several cardiac and respiratory motion compensation techniques have been proposed to overcome this problem. These techniques are based on minimizing, correcting or resolving the motion during the acquisition. This talk will include examples of recently introduced advanced methods to deal with cardiac and respiratory motion, discussing their strengths and limitations.
