MRI for Mixing Quality in Microfluidics

Magnetic Resonance in Chemistry, EarlyView.
Fluidic mixing in a micromixer: Paramagnetic relaxation enhancement and chemical shift differences were explored to reveal mixing quality at the small dimensions of an optically opaque y‐mixer. ABSTRACT Liquid state processes often involve mixing of process streams.

Impact of Partial Echo on 4D Flow MRI: The Insight From Synthetic MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The aim of this study is to investigate the impact of the partial echo on 4D flow MRI sequences thanks to in silico coupled MRI‐CFD (computational fluid dynamics) simulations. Methods Two sequences are studied: one with a full echo (FE) and another using partial echo (PE) with an echo symmetry fraction of 0.75.

Optimized Detection of Left Ventricular Hyperpolarized [1‐13C]Pyruvate Signal in Human Cardiac Metabolic Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aimed to improve the analysis of the left ventricular (LV) blood pool hyperpolarized [1‐13C]pyruvate signal for a more reliable quantification of downstream metabolic outcome. Methods Hyperpolarized [1‐13C]pyruvate magnetic resonance spectroscopic images were acquired dynamically at 3 Tesla in 106 participants (NCT03685175).

Acceleration of Phase‐Modulated Ultrashort Echo Time Sequence for Fast T2 and Adiabatic T1ρ Mapping of the Knee Joints

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and validate an accelerated phase‐modulated ultrashort echo time (PM‐UTE) sequence for volumetric T2 and adiabatic T1ρ (AdiabT1ρ) mapping of both short‐ and long‐T2 tissues in the knee joint. Methods The proposed method estimates and removes the T1‐dependent component from a single reference acquisition, eliminating repeated

Navigator‐Based Slice Tracking for Multiband Accelerated Liver DWI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Clinical liver diffusion‐weighted imaging (DWI) suffers from long measurement time and respiratory motion. In this study, we employ a navigator‐based slice tracking technique (NAV) to prospectively compensate for respiratory motion in multiband (MB) accelerated liver DWI.
