Parent Session: Simultaneous Multiparameter & Multidimensional Cardiovascular MRI

Session Number: WE-04

Overview
Major advancements in simultaneous multicontrast, multiparameter, and multidimensional cardiovascular MRI show promise for markedly simpler, more efficient cardiovascular MRI exams. There are demonstrated benefits for comprehensive tissue characterization, motion handling, and naturally co-registered data ready-made for multiparameter analysis.

This session will cover the current structure of cardiovascular MR examinations, the basics of multicontrast, multiparameter, and multidimensional imaging, and the state of the art in applications of such methods to cardiac and vascular imaging. It will conclude with an outlook on what the cardiovascular MR examination may become as these methods mature.

Two course sections (covering methods and applications) will include three lectures followed by a panel discussion.

Target Audience
Clinicians, physicists, and engineers wishing to learn about and participate in a discussion on cutting-edge developments and applications of multicontrast, multiparameter, and multidimensional cardiovascular MRI.

Educational Objectives
As a result of attending this course, participants should be able to:
- Define the limitations of conventional cardiovascular MRI;
- Show improved technical background, displaying knowledge of methodology such as fingerprinting, multidimensional compressed sensing, and low-rank tensor imaging; and
- Identify the implications of multicontrast, multiparameter, and multidimensional imaging for clinical cardiovascular MRI.

	Background & Overview of Methods
		Current Status of Quantitative CMR in the Clinic Video Permission Withheld Charlotte Manisty
		Basics of Multicontrast/Multiparametric Imaging Watch the Video Yuchi Liu This presentation aims to introduce the scientific/technical basics of multi-contrast/multi-parametric imaging.

	State-of-the-Art Applications & Future Outlook
		State-of-the-Art Vascular Applications Watch the Video Yibin Xie Multicontrast, multiparametric and multidimensional MRI is a group of emerging paradigm-shifting MRI techniques that provides unique advantages over conventional MRI method in imaging speed and motion-robustness. It also offers a powerful platform for quantitative imaging and opens new opportunities for probing various physiological dynamics. In this talk I will provide an overview of the state of the art of vascular imaging based on multicontrast, multiparametric and multidimensional MRI, as well as an outlook for future research directions and clinical translation.
		State-of-the-Art Cardiac Applications Watch the Video Liliana Ma The field of multidimensional and multiparametric imaging has gained increasing traction and momentum with advances in hardware, sampling patterns, and reconstruction techniques. This talk aims to expand on some of the techniques introduced earlier in the session, with an emphasis on state-of-the-art cardiac applications in clinical and patient populations. Techniques covered will include free-running respiratory-resolved 3D cine imaging, 5D flow, MR fingerprinting, multiparametric SAturationg-recovery singleSHot Acquisition, and MR multitasking, as well as advances in multidimensional reconstruction techniques for clinical integration.
		Future Outlook Watch the Video Leon Axel While much progress has been made in the development of methods for multiparameter & multidimensional cardiovascular (CV) MRI, there are many technical challenges remaining to be overcome in clinical applications of them, particularly the difficulties associated with handling the large associated data sets, from data acquisition and image reconstruction, to visualization and analysis. However, if these challenges can be overcome, these new imaging methods can potentially both improve the efficiency of CV MRI, and provide powerful new means for assessing the effect of disease on the cardiovascular system, through integrated and spatially registered displays of structure, function, and tissue properties.
