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…
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…
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…
