0780. 2D
Adiabatic T1ρ Mapping of the Myocardium at 0.55T
D. Si, M. Crabb, S. Littlewood, K. Kunze, C. Prieto, R.
Botnar
School of Biomedical Engineering and Imaging Sciences, King's College London, London, United Kingdom
Impact: Accurate 2D adiabatic T1ρ mapping in a single
breath-hold scan at 0.55T for contrast-free detection of
scar and fibrosis at lower-field.

0781. Simultaneous
Myocardial T1, T2, T1ρ and Fat Fraction Mapping with Hybrid
Dual-echo Cartesian Acquisition and Dictionary Matching
Z. Lyu, H. Huang, H. Hong, J. Hu, L. Hu, Y. Zhong, P.
Hu, H. Qi
School of Biomedical Engineering & State Key Laboratory of Advanced Medical Materials and Devices, ShanghaiTech University, Shanghai, China, Shanghai, China
Impact: The proposed Dixon-MultiMap achieves
simultaneous multiple parameters and fat quantification with
single-shot Cartesian acquisition and dictionary matching,
which has simplified post-processing and holds great
potential for clinical translation.

0782. Serial
Myocardial Fibrosis Assessments Predict Outcomes in Patients
with Hypertrophic Cardiomyopathy: A Cardiac Magnetic Resonance
Study
Y. Tang, S. Zhao
Fuwai Hospital, National Center for Cardiovascular Diseases of China, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China
Impact: In patients with hypertrophic cardiomyopathy,
myocardial fibrosis increases over time. Judicious and
serial assessments of late gadolinium enhancement on cardiac
magnetic resonance can improve risk stratification and
clinical decision-making to help patient management.

0783. Joint
myocardial scar and oedema imaging in the acute STEMI population
using a novel one-click bright- and black-blood LGE and T2
mapping sequence
V. de Villedon de Naide, E. Gerbaud, B. Durand, M.
Villegas-Martinez, K. Narceau, K. He, R. Klaar, T.
Génisson, T. Richard, P. Gut, A. I. Schmid, C. Bazin, I.
Benlala, P. Jaïs, M. Stuber, H. Cochet, A. Bustin
IHU LIRYC, Heart rhythm disease institute, Université de Bordeaux – INSERM U1045, Bordeaux, France
Impact: The proposed ‘one-click’ SPOT-MAPPING permits
easier and faster planning for MR technicians, more comfort
for patients with acute STEMI, promoted by fewer
breath-holds, and a simplified analysis for medical
professionals, through co-registered, qualitative and
quantitative images.

0784. Accurate
Iron Quantification in Acute Hemorrhagic MI: Alleviating Water
Content Sensitivity in Myocardial Edema with Cardiac QSM
Y. Huang, X. Liu, x. Guan, X. Zhang, A. Malagi, G. Anthony,
C-c Yang, L-T Huang, X. Li, G. Yoosefian, X. Bi, D. Li, Q.
Yang, H-J Yang, R. Dharmakumar
Indiana University School of Medicine , Indianapolis, United States
Impact: Cardiac QSM can quantify iron content within
hMI, with greater sensitivity and accuracy in the presence
of myocardial edema than R2* MRI. HDR-QSM may support
reliable iron measurement in studies testing therapies
against iron's adverse post-hMI effects.

0785. Entropy
as a Novel Measure of Myocardial Tissue Heterogeneity for
Prediction of MACE in Patients with Myocarditis
Y. Wang
Fuwai Hospital, Peking Union Medical College, Chinese Academy of Medical Sciences, Beijing, China
Impact: LV entropy is a fully reproducible and highly
prognostic measure of myocardial heterogeneity. It shows
promising ability to predict adverse cardiovascular events
in patients with acute myocarditis.

0786. LV
Late Gadolinium Enhancement for the Primary Prevention of
Ventricular Arrhythmias in Arrhythmogenic Right Ventricular
Cardiomyopathy
Z. Dong, Y. Song, S. Zhao
Fuwai Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, CHN, BEIJING, China
Impact: Our study demonstrated that LV LGE was
independently associated with the first occurrence of
sustained VAs in ARVC and could improve risk prediction of
the proposed 5-year risk calculator, which might further
refine the primary prevention strategies of the disease.

0787. Preliminary
clinical application of free-breathing black-blood myocardial
scar imaging in patients with cardiac implantable devices
P. Gut, H. Cochet, P. Antiochos, G. Caluori, B. Durand, M.
Constantin, K. Vlachos, K. Narceau, A. Masi, J. Schwitter,
F. Sacher, P. Jaïs, M. Stuber, A. Bustin
University Hospital of Lausanne, Lausanne, Switzerland
Impact: Our findings support the clinical use of the
proposed sequence for more accurate myocardial scar
detection in patients with implantable cardiac devices,
without long and tedious breath-holds, which could influence
treatment decisions and improve outcomes by preventing
sudden cardiac death.

0788. Assessing
the Value of Stress Cardiac Magnetic Resonance Imaging in
Detection of Myocardial Ischemia
L. Zhou, J. An, M. Wang, Y. Ge
Fuwai Central China Cardiovascular Hospital, ZhengZhou, China
Impact: This study demonstrates the utility of stress
CMR for identifying CMD, even in patients with
non-obstructive CAD, thus enabling earlier diagnosis and
potential intervention. Further research is needed
concerning the long-term prognostic and therapeutic
utilities of stress CMR for CMD.

Yale School of Medicine, New Haven, United States
Impact:
We propose a highly time-efficient, free-breathing 3D cardiac imaging method that integrates ECV mapping and cine imaging in a single scan with mid-scan contrast agent injection. |
