Fat/Water Separation at 7 T Using a 3D Radial Sequence With Quasi‐Continuous Echo Times

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To achieve a reliable fat/water separation (FWS) at 7 T using a new 3D radial sequence and reconstruction workflow with quasi‐continuous TE sampling. Methods A 3D radial density‐adapted sequence with quasi‐continuous TE sampling was developed for a 7 T whole‐body MRI system.

Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate a motion‐compensated diffusion imaging with phase‐contrast (MC‐DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. Methods Diffusion‐weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI system using three gradient ...

Chemical Shift Separated and Compensated Ultra‐Short Echo‐Time Imaging

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a modified binomial excitation scheme for ultra‐short echo‐time (UTE) imaging that allows for the separation of water and fat signals and the correction of chemical shift artifacts. Methods Theoretical derivation and numerical Bloch simulations were performed for a modified water‐excitation binomial pulse scheme to calculate

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

open access: yesMagnetic 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).

Reducing Inhomogeneous MT (ihMT) Acquisition Time Using Frequency Alternation at Low Duty Cycle for Single Offset (FALSO) MT Preparations

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate Frequency Alternation at Low duty cycle for Single Offset (FALSO) as a novel Magnetization Transfer (MT) preparation scheme to increase speed and/or spatial resolution of inhomogeneous MT (ihMT) MRI by reducing the number of volumes required.
