Hemodynamics and flow by PCMR in large and small vessels
  Figure 363-06-001.  Hemodynamics and Endomyocardial Injury in Severe Aortic Stenosis: Insights from 4D Flow CMR, catheter Pressure and histologic
Ying Zhong, Daniel Giese, Yunzhu Wu, Yueluan Jiang, Guan Wang
The First Hospital of China Medical University, Shenyang, China
Impact: The results of this study suggested that beyond ischemia, shear forces may play a central role in AS-related myocardial remodeling, highlighting wall shear stress derive from 4d flow CMR as a potential imaging biomarker and therapeutic target.
  Figure 363-06-002.  3D Phase Contrast using Balanced Steady-State Free Precession (PC-SSFP) for Improved 4D Flow at Clinical Field Strengths
Jie Xiang, Maolin Qiu, Gigi Galiana, Ipek Buber, Jeremy Steele, Oliver Wieben, Dana Peters
Yale University, New Haven, United States of America
Impact: A non-contrast-enhanced 4D flow MRI using bSSFP was developed at the most commonly used clinical field strengths (1.5T and 3T), which improved image quality and accurately measured flow velocity and volume, showing its potential for more robust intracardiac flow evaluations.
  Figure 363-06-003.  Accelerated Self-gated Dual-VENC 4D Flow enabled using High-VENC with Differentiated Resolution (HDR)
Wenjian Liu, Wenchao Yang, Zijian Zhou, Peng Hu
ShanghaiTech University, Shanghai, China
Impact: Our accelerated HDR technique makes accurate, free-breathing dual-VENC 4D Flow clinically practical. This enables robust velocity quantification in more patients, including those unable to hold their breath, improving diagnostic workflow and making comprehensive flow imaging more routine.
  Figure 363-06-004.  Intracranial 4D Flow of IIH patients pre and post lumbar puncture identifies altered pulse wave modulation
Sergio Dempsey, Jet Wright, Eryn Kwon, Vickie Shim, Samantha Holdsworth, Gonzalo Maso Talou
GE HealthCare, Gisborne, New Zealand
Impact: Intracranial 4D flow analysis pre- and post-lumbar puncture in suspected IIH patients shows stable cerebral blood flow, but marked changes in hemodynamic regulation by the vasculature, indicated by altered vascular effective compliance and pulse wave modulation.
  Figure 363-06-005.  Image2Flow Transient: Fast Estimation of Transient Pulmonary Artery Flow Fields from 3D Cardiac MRI
Anirudh Raman, Tina Yao, Jennifer Steeden, Vivek Muthurangu
University College London, London, United Kingdom
Impact: We developed a deep learning model that generates a 3D pulmonary artery mesh with time-varying flow fields from a single 3D cardiac MRI input—the first to generate both volumetric mesh and transient CFD results in a single inference.
  Figure 363-06-006.  Camera-based Respiratory Binning for 4D flow MRI at 0.6T
Sébastien Emery, Jacob Malich, Luuk Jacobs, Gloria Wolkerstorfer, Yiming Dong, Martijn Nagtegaal, Sebastian Kozerke
Institute for Biomedical Engineering, University and ETH Zurich, Zurich, Switzerland
Impact: Camera-based respiratory binning provides a viable alternative at lower field strengths, where MR-based binning may be limited by reduced SNR, particularly in subjects with larger body-size or higher fat-mass.
  Figure 363-06-007.  Dampened Limbic and Striatal Pulsatility in Idiopathic Intracranial Hypertension: Insights from q-aMRI and Flow MRI
Jet Wright, Sergio Dempsey, Alireza Sharifzadeh-Kermani, Paul Condron, Matthew McDonald, Sarah-Jane Guild, Graham Wilson, David Dubowitz, Miriam Scadeng, Leigh Potter, Daniel Cornfeld, Itamar Terem, Eryn Kwon, Helen Danesh-Meyer, Gonzalo Maso Talou, Samantha Holdsworth, Vickie Shim
Mātai Medical Research Institute, Gisborne, New Zealand
Impact: Conventional flow processing techniques are poor at distinguishing controls from IIH pre- or post-LP. Up-and-coming advanced MRI analysis software for 4D CBF and q-aMRI for regional brain displacement reveal marked group differences, paving a new way to understand pressure-related disorders.
  Figure 363-06-008.  Intracranial 4D Flow MRI across field strengths – experimental in-vitro study at 1.5, 3, and 7T
Ali El Ahmar, Patrick Winter, Oliver Welin Odeback, David Marlevi, Susanne Schnell, Alexander Fyrdahl
University of Greifswald, Greifswald, Germany
Impact: Using a neurovascular flow phantom imaged at 1.5, 3, and 7T, we examined field strength effects on 4D Flow MRI. Maximum VNR increased with field strength, but both 1.5T and 7T showed lower peak and mean flow rates than 3T.
  Figure 363-06-009.  Asymmetric 5-point 4D Flow MRI for dual-VENC velocity and turbulent kinetic energy encoding
Chiara Trenti, Federica Viola, Sohaib Qazi, Twan Bakker, Tamara Bianchessi, Tino Ebbers, Petter Dyverfeldt
Linköping University, Linköping, Sweden
Impact: The proposed asymmetric 5-point scheme facilitates clinical adoption of 4D Flow MRI as it accurately resolves low and high velocities, as well as turbulent kinetic energy, with minimal addition in scan time.
  Figure 363-06-010.  Validation of deep-learning-based super-resolution for 4D-flow MRI haemodynamic quantification
Yicheng Wang, Hernán Mella, Julio Garcia, Sergio Uribe, Julio Sotelo
Monash University, Melbourne, Australia
Impact: By recovering fine-scale flow features and improving haemodynamic accuracy, deep-learning-based super-resolution can help establish 4D-flow MRI as a more quantitative and clinically reliable tool for assessing vascular function and disease.
  Figure 363-06-011.  Empirical Correction of the Spatial Dependence of VENC due to MRI Gradient Non-linearities using a Rotational Phantom
Hannes Dillinger, Sebastian Schmitter
Physikalisch-Technische Bundesanstalt (PTB), Braunschweig and Berlin, Berlin, Germany
Impact: Spatially-dependent VENC correction enables more accurate quantitative flow assessment across extended FOVs in PC-MRI. A simple phantom measurement and 30min scan time may enable broad acceptance.
  Figure 363-06-012.  4D bSSFP MRI and 4D flow MRI to assess changes in aortic motion and hemodynamics after root replacement surgery in Marfan
Daan Bosshardt, Renske Merton, Eric Schrauben, Aart Nederveen, Moniek Cox, Danielle Robbers-Vissers, Maarten Groenink, Pim van Ooij
Amsterdam University Medical Center, University of Amsterdam, Amsterdam, Netherlands
Impact: Pre- and post-surgery 4D bSSFP and flow MRI showed that placing a graft decreases ascending aortic displacement and distensibility and increases velocity. In the proximal descending aorta, changes in distensibility were noted that could alter wall properties in the long-term.
  Figure 363-06-013.  Assessment of Left Ventricular Hemodynamics with 4D Flow MRI in Hypertensive Patients Post-Treatment
Shan Jiang, Yang Song, Wenjia Wang
Central Hospital of Dalian University of Technology, dalian, China
Impact: Incorporating 4D Flow MRI-based KE assessment enhances the non-invasive evaluation of treatment response in hypertension. Blood pressure control and reverse structural remodeling emerged as key independent predictors of hemodynamic recovery, supporting their potential as functional biomarkers for guiding personalized therapy.
  Figure 363-06-014.  Cerebrovascular 5D flow MRI
Luuk Jacobs, Patrick Thurner, Sebastian Kozerke
Institute for Biomedical Engineering, University and ETH Zurich, Zurich, Switzerland
Impact: We propose a high-resolution cerebrovascular 5D flow MRI framework, facilitating full-field quantification of respiratory flow modulation in complex arterial and venous structures and modulation of arterial-to-venous dynamics such as transit time and potential 3D hemodynamic biomarkers such as relative pressure.
  Figure 363-06-015.  Ferumoxytol-enhanced whole-heart 4D flow on a commercial 0.55T system
Syed Murtaza Arshad, Salman Pervaiz, Preethi Subramanian, YINGMIN LIU, Christopher Crabtree, Orlando Simonetti, Juliet Varghese, Rizwan Ahmad
The Ohio State University, Columbus, United States of America
Impact: This work demonstrates the feasibility of ferumoxytol-enhanced whole-heart 4D flow MRI at 0.55T with preserved net-flow accuracy versus 3T. These results support low-cost, contrast-enhanced whole-heart flow imaging at lower field strength and motivate continued development toward broader clinical access.
  Figure 363-06-016.  Hemodynamics contribute to pulsatile tinnitus in sigmoid sinus wall dehiscence with idiopathic intracranial hypertension
Lanyue Chen, Xiaobo Ma, Xiancong Liu, Haining Wei, Rui Li, Zhaohui Liu
Beijing Tongren Hospital, Capital Medical University, Beijing, China
Impact: Hemodynamic abnormalities may help to understand the mechanism of sigmoid sinus wall dehiscence-pulsatile tinnitus patients with idiopathic intracranial hypertension. The combination of hemodynamic indicators may serve as a valuable noninvasive tool to improve the accuracy of etiological diagnosis.
