Overview
This session will introduce some more recently introduced or advanced contrast mechanisms available in cardiovascular MR that are not yet widely used in routine clinical cardiovascular MR, but some of which are likely to have a clinical impact in the future.
Target Audience
Physicists, engineers, and clinicians with a basic knowledge of cardiovascular MR but who are keen to learn more about advanced contrast techniques.
Educational Objectives
As a result of attending this course, participants should be able to:
- Identify novel advanced contrast mechanisms in cardiovascular MR with a future clinical impact;
- List unmet clinical needs which the advanced contrast mechanisms may address; and
- Explain the challenges and potential solutions when acquiring, reconstructing, and interpreting cardiovascular MR with the advanced contrast mechanisms listed.
| 13:45 | | T1ρ Contrast in Cardiovascular MRI Chiara Coletti Keywords: Contrast mechanisms: Rotating frame relaxometry, Cardiovascular: Myocardium T 1ρ mapping is rapidly emerging as a promising tool for non-invasive tissue characterization in cardiac MRI and beyond. T 1ρ relaxation is sensitive to molecular interactions in the low frequencies range, from tenths to thousands of Hz, making it a great candidate to probe the interactions betweeen water and macromolecules without the use of external contrast agents. In cardiac MR, T 1ρ mapping has shown diagnostic value for both ischemic and non-ischemic cardiomyopathies. In this educational we will explore the origin of T 1ρ relaxation, discuss how to measure myocardial T 1ρ times and give a brief overview of current applications and challenges. |

| 14:45 | | MR Spectroscopy in Cardiac MRI Ladislav Valkovič Keywords: Cardiovascular: Cardiac metabolism, Contrast mechanisms: Spectroscopy, Contrast mechanisms: Non-Proton Whether you are working in the field of cardiac MRI, or just want to start exploring this exciting organ this talk is meant for you. I will provide an overview of the current status of metabolic imaging of the heart using multinuclear MR Spectroscopy, focusing on its challenges and current use. I will add also a few ideas for potential future directions of the field. |
| 15:15 | | Cardiac Diffusion Weighed & Tensor Imaging Kévin Moulin Keywords: Contrast mechanisms: Diffusion, Cardiovascular: Cardiac This educational presentation will focus on the technical advancements in the emerging field of cardiac diffusion imaging. Initially, we'll explore the impact of cardiac motion on the diffusion signal and examine the various diffusion encoding techniques devised to mitigate it. Additionally, we'll investigate respiratory motion and explore methods for imaging during free breathing. Subsequently, we'll delve into the fundamental principles underlying cardiac diffusion tensor reconstructions and the primary diffusion markers derivable from them. Lastly, we'll explore several clinical applications of cardiac diffusion imaging. |
