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.

A Rapid T1‐Independent Sequence for Cerebrospinal Fluid Water Standard Correction: Application to Improved Proton Density Mapping in Brain

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve brain water content measures relative to cerebrospinal fluid (CSF) by including a rapid T1‐independent sequence to correct for CSF T1 errors. Methods Proton density (PD) was estimated from a 3D multiple echo gradient echo sequence by extrapolating to TE = 0 and then correcting for T1 losses using a T1 map from 3D MP2RAGE. To

Towards Faster Fetal 3D CINE Cardiac MRI Reconstruction Using Region‐Optimized Virtual Coils (ROVir)

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate, in a feasibility study, a computationally efficient image‐reconstruction pipeline for 3D balanced steady state free precession (bSSFP) CINE fetal cardiac MRI that reduces radial streaking artifacts, increases effective temporal resolution, and improves diagnostic image quality compared with previous work ...

Spatially Aware Acquisition‐Independent Deep Learning for IVIM MRI Parameter Estimation in Patients With Esophageal Cancer

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Neural controlled differential equations (NCDEs) recently emerged as a robust deep learning approach for quantitative MRI parameter estimation. NCDEs offer flexibility to changes in acquisition protocols by modeling the signal evolution dynamics. However, NCDE implementations operate on a voxel‐by‐voxel basis and cannot exploit spatial

Enhanced 3D Filter‐Exchange Imaging Using Multi‐Slab Acquisition

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Starting from the implementation of a single‐slice FEXI sequence, a 3D method was developed to accelerate a FEXI experiment and acquire a multi‐slice volume. Methods 3D multi‐slab FEXI divides the volume of interest into different slabs.
