Ultimate Intrinsic SNR Depends on B0 Orientation

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This work aims to investigate the effect of B0$$ {B}_0 $$ orientation on the uiSNR in MRI. Methods Electromagnetic simulations were performed on both realistic body models and simplified geometric models. Comparisons between (1) opposite B0$$ {B}_0 $$ directions along the head‐foot (HF) axis, corresponding to head‐first and feet‐first ...

Design of an In Vivo‐Like Phantom for Quantitative Body CEST MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To design and validate a reproducible in vivo‐like fat‐containing CEST phantom that enables robust quantitative CEST MRI for body applications by providing physiologically realistic relaxation properties, relevant endogenous CEST contrasts (amide, guanidino, rNOE, and semi‐solid MT), and a controlled fat component.

Whole‐Brain Diffusion MRI at 7T With Universal Multiband GRAPE pTx Pulses

Magnetic Resonance in Medicine, EarlyView.
Purpose To improve signal strength and homogeneity of whole‐brain diffusion‐weighted imaging (DWI) at 7T. Methods Universal multiband excitation and refocusing pulses were optimized with the gradient ascent pulse engineering (GRAPE) algorithm across a database of B1+$$ {B}_1^{+} $$ and B0$$ {B}_0 $$ maps obtained from 20 subjects.

Predicting Mesoscopic Larmor Frequency Shifts in Ex Vivo Porcine Optic Nerve

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Larmor frequency shifts in white matter (WM) vary with fiber orientation due to anisotropic microstructure. Since clinical voxels are significantly larger than these microscopic frequency variations, the measured signal represents a bulk average of local shifts.

Online Crowdfunding Campaigns for People Living With ALS Demonstrate Financial Burden and Unmet Needs

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims People living with amyotrophic lateral sclerosis (ALS; pALS) have extensive care needs, from wheelchairs to feeding tubes to caregiving support. The financial impact of these needs on pALS and their caregivers (cALS) has not been fully explored.
