Pilot tone-guided focused navigation for free-breathing whole-liver fat-water and T2* quantification
Adèle LC Mackowiak, Christopher W Roy, Mariana BL Falcão +7
Purpose To achieve whole-liver motion-corrected fat fraction (FF) and R2* quantification with a 3-minute free-breathing (FB) 3D radial isotropic acquisition, for increased organ co…
Fat-free noncontrast whole-heart CMR with fast and power-optimized off-resonant water excitation pulses
Adèle L. C. Mackowiak, Davide Piccini, Jessica A. M. Bastiaansen
Background: Cardiovascular MRI (CMR) faces challenges due to the interference of bright fat signals in visualizing anatomical structures. Effective fat suppression is crucial when…
Getting the phase consistent: The importance of phase description in balanced steady-state free precession MRI of multicompartment systems
Nils M. J. Plähn, Simone Poli, Eva S. Peper +4
Purpose: Determine the correct mathematical phase description for balanced steady-state free precession (bSSFP) signals in multicompartment systems. Theory and Methods: Based on pu…
Motion-resolved fat-fraction mapping with whole-heart free-running multiecho gre and pilot tone
Adèle L. C. Mackowiak, Christopher W. Roy, Jérôme Yerly +6
PURPOSE To develop free-running multi-echo GRE for cardiac- and respiratory-motion-resolved whole-heart fat fraction quantification. METHODS Multi-echo readouts optimized for water…
Radical-free hyperpolarized MRI using endogenously-occurring pyruvate analogues and UV-induced nonpersistent radicals
Claudia C Zanella, Andrea Capozzi, Hikari AI Yoshihara +4
It was demonstrated that nonpersistent radicals can be generated in frozen solutions of metabolites such as pyruvate by irradiation with ultraviolet (UV) light, enabling radical-fr…
A robust broadband fat suppressing phaser T2 preparation module for cardiac magnetic resonance imaging at 3T
Lionel Arn, Ruud B van Heeswijk, Matthias Stuber +1
Purpose: Designing a new T2 preparation (T2-Prep) module in order to simultaneously provide robust fat suppression and efficient T2 preparation without requiring an additional fat…
SPARCQ: A new approach for fat fraction mapping using asymmetries in the phase-cycled bSSFP signal profile
Giulia MC Rossi, Adele LC Mackowiak, Tom Hilbert +4
Purpose: To develop SPARCQ (Signal Profile Asymmetries for Rapid Compartment Quantification), a novel approach to quantify fat fraction using asymmetries in the phase-cycled bSSFP…
Flexible water excitation for fat-free MRI at 3 Tesla using lipid insensitive binomial off-resonant RF excitation (LIBRE) pulses
Jessica AM Bastiaansen, Matthias Stuber
Purpose: To develop a robust and flexible low power water excitation pulse that enables effective fat suppression at high magnetic field strength. Methods: A water excitation metho…
Noncontrast free-breathing respiratory self-navigated coronary artery cardiovascular magnetic resonance angiography at 3 T using lipid insensitive binomial off-resonant excitation (LIBRE)
Jessica A. M. Bastiaansen, Ruud B. van Heeswijk, Matthias Stuber +1
Robust and homogeneous lipid suppression is mandatory for coronary magnetic resonance angiography (MRA) since coronary arteries are commonly embedded in fat. However, effective lar…
