New MR techniques in perfusion MRI and coronary MRA
Skill Level: Intermediate
  Figure 467-03-001.  Physiology-driven, Patient specific Parameter Optimization for Coronary MR Angiography
yue jiang, da wei zhou, Junye Yao
jiangsu province official hospital, Nan jing, China
Impact: This physiology-driven framework transforms expert-dependent CMRA parameter tuning into an interpretable, patient-specific optimization model. It enhances diagnostic accuracy and image quality within clinical efficiency limits, enabling intelligent, vessel-aware pre-scan planning and standardizing coronary MR imaging across institutions.
  Figure 467-03-002.  Nonrigid Motion Correction for Free-Breathing Dixon Coronary MR Angiography Using FMCW Radar-Primed Autofocusing
Zhihua Chen, Huili Yang, Wenlei Shang, Zijian Zhou, Yuan Feng, Yining Wang, Haikun Qi, Peng Hu
School of Biomedical Engineering, ShanghaiTech University, Shanghai, China
Impact: This study preliminarily demonstrates the feasibility of radar-primed autofocusing for free-breathing Dixon CMRA, improving the acquisition efficiency and guaranteeing the image quality.
  Figure 467-03-003.  Ultrahigh-Field 5T MRI Improves Coronary Plaque Imaging vs 3T: Image Quality and Histology-Validated AHA Classification
Yue Sun, Qile Zhang, Ke Xue, Yuan Feng, Peng Hu, Yining Wang
State Key Laboratory of Complex Severe and Rare Diseases, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Address: No.1, Shuaifuyuan, Dongcheng District, Beijing 100730, China
Impact: 5T MRI outperforms 3T MRI in both image quality and diagnostic accuracy for coronary plaque characterization. These findings provide a foundation for future in vivo studies to further evaluate its potential in non-invasive plaque assessment.
  Figure 467-03-004.  Free-breathing ASL-based interleaved stack-of-stars (iSoS) whole myocardium perfusion along with motion robust MRCA
Mitsue MIYAZAKI, Vadim Malis, Yoshiki Kuwatsuru, Yuko Tada, Anya Mesa, Paul Kim
University of California, San Diego, United States of America
Impact: Together with robust zcFFE-MRCA with scan time of less than 4.5 minutes, free-breathing ASL-based 3D iSoS with mPASL may provide additional insights into cardiac MRI, especially in CAD patients with stents and coronary artery bypass graft (CABG).
  Figure 467-03-005.  Quantitative perfusion demonstrates resting myocardial hyperemia in sickle cell anemia patients
Jon Detterich, Sophia Cui, Rebecca Stull, Andrew Cheng, Jamie Harrington, Kelvin Chow, Tess Wallace, Rachel Davids, John Wood
Children's Hospital Los Angeles, Los Angeles, United States of America
Impact: Patients with sickle cell anemia have diffuse vascular disease. Cardiac MRI can evaluate myocardium structure beyond traditional cardiac function using parameteric mapping and newer quantitative perfusion. We describe our use of quantitative perfusion in sickle cell anemia.
  Figure 467-03-006.  Cardiac Phase Variability of Optimal Coronary Delineation in a Young Cohort of Patients with Congenital Heart Disease
Heidi White, Augustin Ogier, Jérôme Yerly, Isabel Montón Quesada, Adele Mackowiak, Stanislas Rapacchi, Milan Prša, Estelle Tenisch, Christopher Roy, Matthias Stuber
Lausanne University Hospital (CHUV) and University of Lausanne (UNIL), Lausanne, Switzerland
Impact: This study challenges the long-standing assumption that mid-diastole is the optimal phase for coronary MRI. In young CHD patients, the best coronary depiction varies between patients, supporting a shift from fixed mid-diastolic targeting toward patient-specific, retrospectively determined cardiac phase selection.
  Figure 467-03-007.  Kolmogorov--Arnold Networks for Robust Myocardial Blood Flow Mapping
Shen Zhao, Sizhuo Liu, Xitong Wang, Quan Chen, Michael Salerno
UCSF-Radiology, United States of America
Impact: Kolmogorov--Arnold Network (KAN) enables interpretable, non-iterative myocardial blood flow (MBF) mapping with substantial inference speed gains, supporting near real-time perfusion assessment and scalable cohort analyses.
  Figure 467-03-008.  Clinical PET/MR perfusion protocol for comprehensive evaluation of coronary artery disease
Miia Pitkonen, Toni Ihalainen, Eero Hippeläinen, Outi Sipilä, Jyri Lehto, Valtteri Uusitalo
University of Helsinki and Helsinki University Hospital, Helsinki, Finland
Impact: The presented cardiac 15O-water PET/MRI protocol enables simultaneous quantitative perfusion and detailed tissue assessment within one hour, offering a new platform for studying myocardial pathophysiology and advancing multimodal cardiac imaging research.
  Figure 467-03-009.  Quantitative Myocardial Blood Flow Under Dobutamine Stress MRI – Anomalous Right Coronary Origin
Jon Detterich, Sophia Cui, Rebecca Stull, Andrew Cheng, Jamie Harrington, Kelvin Chow, Tess Wallace, Rachel Davids, John Wood
Children's Hospital Los Angeles, Los Angeles, United States of America
Impact: Sudden cardiac events in adolescents with anomalous aortic origin of the right coronary artery is a problem with very little risk stratification data. Quantitative perfusion may provide improved risk stratification for patients prior to sudden cardiac events.
  Figure 467-03-010.  Pseudo-continuous arterial spin labeling (PCASL) MRI for assessment of myocardial perfusion: Preliminary results
Petros Martirosian, Anja Hanser, Rolf Pohmann, Martin Schwartz, Cecilia Liang, Thomas Küstner, Fritz Schick
University Hospital of Tuebingen, Tuebingen, Germany
Impact: The PCASL technique allows effective labeling of blood flow through the left ventricular outflow tract into the aorta and appears to be suitable for noninvasive imaging of myocardial perfusion. However, systematic measurements are needed to improve the myocardial perfusion signal.
  Figure 467-03-011.  Quantitative CMR Myocardial Perfusion Imaging: A New Era of Heart Imaging?
Suraj Gowda, Javier Sánchez-González, Yogesh k Mariappan, Rupesh Vakkachi Kandi, Suja Saraswathy, Vimal Raj, Ann Jose
Narayana Health, Bangalore, India
Impact: Quantitative myocardial perfusion imaging improves detection of ischemia compared to qualitative methods, especially in balanced ischemia and microvascular dysfunction. Adopting quantitative analysis in routine practice may enhance diagnostic accuracy, reduce subjectivity, and guide better patient management in ischemic heart disease.
  Figure 467-03-012.  Myocardial perfusion index derived from baseline CMR first-pass perfusion imaging for predicting the CTRCD
Yufei Deng, Qian Xu, Hesong Shen, Jiuquan Zhang
Chongqing University Cancer Hospital & Chongqing Cancer Institute & Chongqing Cancer Hospital, ChongQing, China
Impact: Baseline CMR-derived myocardial PI value of the middle slice effectively predicts anthracycline-induced CTRCD; combining it with GLS/HFA-ICOS enhances management, aiding precise risk stratification and new cardio-oncology research.
  Figure 467-03-013.  Whole-heart 3D first-pass perfusion cine imaging
Zhenyu Bu, YINGMIN LIU, Yu Ding, Muhammad Sultan, Yixuan Liu, Orlando Simonetti, Yuchi Han, Rizwan Ahmad
The Ohio State University, Columbus, United States of America
Impact: Conventional myocardial first-pass perfusion (FPP) MRI acquires 2D slices with limited spatial coverage and diagnostic confidence. For more comprehensive ischemia assessment, we developed a 3D FPP cine technique that achieves whole-heart coverage from a single 3D acquisition.
  Figure 467-03-014.  Feasibility of Whole-Heart Myocardial Perfusion MRI with a Slice Acceleration Factor of Five
Johnathan Le, Jason Mendes, Ravi Ranjan, Andrew Arai, Edward DiBella, Ganesh Adluru
University of Utah, Salt Lake City, United States of America
Impact: Radial SMS saturation recovery with $MB=5$ can produce similar image quality and comparable myocardial perfusion maps as conventional standard sequences while providing increased slice coverage for better determination of the extent of ischemia.
