4338. Can
spleen T1 mapping be used as a marker of adequate adenosine
response in stress perfusion CMR?
S. Solis-Barquero, V. Aramendia-Vidaurreta, A. Ezponda, M.
Vidorreta, M. Pascual, G. Bastarrika, M. Fernandez-Seara
Clinica Universidad de Navarra, Pamplona, Spain
Impact: This study suggest that splenic T1 changes can
detect splenic switch-off during adenosine stress CMR,
potentially enabling real-time stress adequacy assessment.
However, it raises questions about adenosine’s effects on
splenic perfusion and the link of splenic switch-off to
myocardial response.

Left Ventricular Cardiomyopathy: Non-ischemic Myocardial Scar as
Predictor of Adverse Cardiovascular Events
M. Jiang, M. Lu
Department of Magnetic Resonance Imaging, Fuwai Hospital, State Key Laboratory of Cardiovascular Disease, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China
Impact: A larger population with longer follow-up is
warranted to confirm this finding and explore optimal
treatment decisions according to different risk
stratification.

4340. Automatic
Inversion Time Tracking for Late Gadolinium Enhancement Cardiac
MRI
E. Peterson, J. J. He, W. Overall
Vista.ai, Palo Alto, United States
Impact: Removing the need for the operator to monitor
Inversion Time (TI) frees them to monitor other aspects of
the scanning process. When TI determination can be scheduled
and acquired automatically it automates and optimizes
critical diagnostic imaging.

Dharmakumar, H-J Yang
Indiana University School of Medicine , Indianapolis, United States
Impact: This pilot study demonstrates HDR-QSM’s
potential for assessing myocardial inflammation, providing a
promising tool to monitor post-MI healing and inform
targeted therapeutic interventions. FDG PET imaging will be
conducted in future studies to validate our findings

University of Missouri-Columbia, Columbia, United States
Impact: PerfGen enables high-quality myocardial
perfusion MRI, complementing GRAPPA or similar methods to
improve imaging speed with real-time displays. This
conditional diffusion-based super-resolution approach
generates multiple contrast phases and complements GRAPPA or
similar methods, further advancing myocardial perfusion
imaging.

Impact: Free-breathing 3D Dixon LGE
imaging with image-based navigation is clinically
feasible, shows agreement with the 2D reference method,
clearly delineates fibrosis and fat infiltration, and can be
performed in a shorter scan time than that of the 2D
sequence.

such information from hyperpolarized 13C
MRI could aid in diagnosis and translation of metabolic
therapies.
