Phase‐Sensitive Modeling Improves Fat DESPOT Multiparametric Relaxation Mapping in Fat‐Water Mixtures

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve on a multiparametric technique—known as Fat DESPOT—to map the fat‐ and water‐specific R1$$ {R}_1 $$ (R1f$$ {R}_{1f} $$, R1w$$ {R}_{1w} $$), R2*$$ {R}_2^{\ast } $$, and proton density fat fraction (PDFF) by upgrading the parameter initialization and introducing explicit model sensitivity to the complex phase of the water and ...

Comparative Performance Analysis of an Open Source Motion‐Compensated Cardiac Diffusion Sequence Across Different MRI Systems and Gradient Strengths—A Pilot Study

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To validate the performance of an open‐source cardiac diffusion sequence framework and to investigate hardware‐based performance differences. Methods Three second order motion compensated sequence files were compiled using Pulseq and applied across different MRI systems to image five volunteers.

Time‐Efficient Interleaved Spin Density‐Weighted and Inversion Recovery 23Na MRI of the Human Calf Muscle at 7 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Spin density‐weighted (SDW) and inversion recovery (IR) 23Na MRI provide different sodium contrasts with complementary information. Therefore, the aim was to develop a time‐efficient sequence scheme capable of providing both contrasts by acquiring SDW and IR 23Na MRI data within a single sequence without additional measurement time ...
