SMRT Session

14:00 - 16:00

Moderators: Maureen Hood & Michael Salerno

Session Number: SMRT-IS

Parent Session: SMRT: ISMRM-SMRT Joint Forum Session

Session Number: SMRT-IS

Overview
Myocardial mapping methods are valuable for characterizing infiltrative diseases and can be performed without the use of contrast agents. The aim of this forum is to further the understanding of myocardial mapping techniques and engage in discussion about the advantages as well as limitations of these techniques. In this forum, a clinician, a radiographer/technologist, and a scientist will present their professional perspectives by providing clinical examples where myocardial mapping assisted in diagnosis, discuss common problems when performing these protocols, and give a summary of improvements to existing techniques designed to improve myocardial mapping.

Target Audience
Radiographers, MR physicists or engineers, and clinicians with an interest in quantitative cardiac MRI. A current understanding of cardiac MR acquisition will be useful, but newcomers will also benefit greatly from this session ahead of embarking on a new skill set with cardiac MR.

Educational Objectives
As a result of attending this course, participants should be able to:
- List the benefits of myocardial mapping and how the techniques may assist in clinical diagnosis;
- Evaluate common problems when performing these protocols and how to overcome them;
- Identify technical reasons why these mapping techniques are challenging; and
- Describe new methods for mapping and how they could improve the clinical workflow.

		Myocardial T1, T2, T2* & ECV Mapping: The Clinical Promise Watch the Video Wiphada Patricia Bandettini • Parametric mapping tissue characterization has moved beyond the research realm and is now applicable within the clinical setting. Parametric mapping adds value to CMR, taking imaging beyond that of anatomy. Native T1, T2, and T2* offer non-contrast options to better characterize the myocardium. Extracellular volume fraction (ECV) helps to identify edema diffuse fibrosis. Edema, inflammation, fibrosis, and infiltration may be identified noninvasively by CMR. The tools of T1, T2, T2*, and ECV are ready for daily clinical use…if the appropriate QA and standards are followed. Parametric mapping offers improved diagnosis, management, and prognosis in the patient with cardiovascular disease.

		Myocardial T1, T2, T2* & ECV Mapping: Upcoming Technical Solutions to Practical Problems Watch the Video Jesse Hamilton This presentation will cover recent technical advances in myocardial T1, T2, T2, and ECV mapping. First, a review of conventional cardiac parameter mapping methods will be presented including MOLLI and SASHA (T1 mapping), T2-prepared gradient echo (T2 mapping), and multi-echo gradient echo (T2 mapping). Next, we will discuss recent technical innovations that address practical challenges in parameter mapping including motion correction, high-resolution 3D mapping, multiparametric techniques, free-running techniques, and deep learning for parameter mapping.
