| 15:25 | | Cardiac MRI to Characterize Diastolic Function Masaki Ishida Keywords: Cardiovascular: Cardiac, Cardiovascular: Cardiac function, Cardiovascular: Myocardium Diastolic dysfunction, a significant contributor to HFpEF, presents a formidable diagnostic challenge due to its diverse etiologies and complex pathophysiology. While cardiac catheterization is currently considered the reference standard for assessing LV diastolic function, it has inherent limitations, notably its invasiveness. Cardiac MRI offers a range of non-invasive, objective, and reproducible measures of diastolic function, including ventricular and atrial volumes, myocardial strain, native T1 and ECV, 4D flow, and exercise real-time cine index. These advanced CMR techniques substantially enhance noninvasive and objective evaluation of diastolic function and refine clinical management strategies for patients with diastolic dysfunction and HFpEF. |
| 15:50 | | AI-Driven CMR Chen Qin Keywords: Image acquisition: Machine learning, Cardiovascular: Cardiac Artificial intelligence (AI) is making a significant impact on all aspects of cardiovascular magnetic resonance (CMR) imaging. In this talk, we will focus on discussing the recent development of DL in CMR imaging workflow, from the reconstruction of accelerated signals to automatic quantification of clinically useful information. Specifically, we will describe how DL methods can be used for reconstruction of accelerated dynamic cine CMR imaging. We will also show the utility of DL for CMR analysis, with a particular focus on CMR segmentation and motion tracking. Finally, we will briefly discuss about their current limitations, challenges, and future opportunities. |

| 16:40 |  | 4D Flow MRI Susanne Schnell Keywords: Cardiovascular: Hemodynamics, Contrast mechanisms: Flow, Image acquisition: Quantification Phase-contrast MRI is an angiography technique that uses bipolar gradients to encode tissue or fluid motion into the MRI signal phase. If measured in 2D with 1-directional encoding this is termed 2D Phase-Contrast MRI. Extended to a time-resolved heart or pulse rate-triggered 3D sequence with 3-directional velocity encoding, this is termed 4D flow MRI. Error sources will be described throughout the course as well as data analysis and quantification approaches. Further extensions such as dual- and multi-venc, and 5D flow MRI will be described. Finally, applications in the thorax, head, and abdomen will be introduced. |
