A Guidewire Trajectory Generation Tool for Interventional MRI Simulations
Fatima Ben Haj, Jeffrey Hand, Shaihan Malik +1
Significance: RF-induced heating of endovascular devices limits MRI-guided interventions, including targeted drug delivery to brain tumors. Purpose: To present a tool that rapidly…
From Offline to Inline Without Pain: A Practical Framework for Translating Offline MR Reconstructions to Inline Deployment Using the Gadgetron Platform
Zihan Ning, Yannick Brackenier, Sarah McElroy +23
Purpose: To develop and validate a practical framework to overcome common issues in inline deployment of established offline MR reconstruction, including (1) delay from lengthy rec…
Controlling sharpness, SNR and SAR for 3D FSE at 7T by end-to-end learning
Peter Dawood, Martin Blaimer, Jürgen Herrler +5
Purpose: To non-heuristically identify dedicated variable flip angle (VFA) schemes optimized for the point-spread function (PSF) and signal-to-noise ratio (SNR) of multiple tissues…
Real-time fetAl brain and placental T2* mapping at 0.55T low-field MRI (RAT)
Jordina Aviles Verdera, Sara Neves Silva, Raphael Tomi-Tricot +6
Purpose: To provide real-time quantitative organ-specific information - specifically placental and brain T2* - to allow optimization of the MR examination to the individual patient…
MR sequence design to account for non-ideal gradient performance
Daniel J West, Felix Glang, Jonathan Endres +4
MRI systems are traditionally engineered to produce close to idealized performance, enabling a simplified pulse sequence design philosophy. An example of this is control of eddy cu…
Universal pulses for homogeneous excitation using single channel coils
Ronald Mooiweer, Ian A. Clark, Eleanor A. Maguire +3
Purpose: Universal Pulses (UPs) are excitation pulses that reduce the flip angle inhomogeneity in high field MRI systems without subject-specific optimization, originally developed…
An 8 channel parallel transmit system with current sensor feedback for MRI-guided interventional applications
Felipe Godinez, Raphael Tomi-Tricot, Matthias Barthel +5
Background: Parallel transmit (pTx) has introduced many benefits to MRI with regard to decreased specific absorption rates and improved transmit field homogeneity, of particular im…
Magnetization Transfer-Mediated MR Fingerprinting
Daniel J. West, Gastao Cruz, Rui P. A. G. Teixeira +5
Purpose: Magnetization transfer (MT) and inhomogeneous MT (ihMT) contrasts are used in MRI to provide information about macromolecular tissue content. In particular, MT is sensitiv…
Efficiency analysis for quantitative MRI of T1 and T2 relaxometry methods
David Leitão, Rui Pedro A. G. Teixeira, Anthony Price +3
This study presents a comparison of quantitative MRI methods based on an efficiency metric that quantifies their intrinsic ability to extract information about tissue parameters. U…
Fetal whole-heart 4D imaging using motion-corrected multi-planar real-time MRI
Joshua FP van Amerom, David FA Lloyd, Maria Deprez +7
Purpose: To develop a MRI acquisition and reconstruction framework for volumetric cine visualisation of the fetal heart and great vessels in the presence of maternal and fetal moti…
Integrated and efficient diffusion-relaxometry using ZEBRA
Jana Hutter, Paddy J Slator, Daan C Christiaens +6
The emergence of multiparametric diffusion models combining diffusion and relaxometry measurements provide powerful new ways to explore tissue microstructure with the potential to…
Extended Phase Graph formalism for systems with Magnetization Transfer and Chemical Exchange
Shaihan J. Malik, Rui P. A. G. Teixeira, Joseph V. Hajnal
An Extended Phase Graph framework for modelling systems with exchange or magnetization transfer (MT) is proposed. The framework, referred to as EPG-X, models coupled two-compartmen…
