Mapping a reproducible water fraction and T1 using MP2RAGE and variable flip angle quantitative MRI protocols

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Water fraction (WF) estimation, a form of quantitative MRI mapping, is typically performed using the variable flip angle (VFA) approach. In this study, WF estimation was extended to include the magnetization prepared with 2 rapid gradient echoes (MP2RAGE) protocol.

Advancing whole‐brain BOLD functional MRI in humans at 10.5 T with motion‐robust 3D echo‐planar imaging, parallel transmission, and high‐density radiofrequency receive coils

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To demonstrate the feasibility and performance of whole‐brain blood oxygen level–dependent functional MRI (fMRI) in humans at 10.5 T by combining motion‐robust three‐dimensional gradient‐echo echo‐planar imaging, parallel transmission, and high‐density radiofrequency (RF) receive coils.

A Subvoxel Correction of Boiling‐Induced Susceptibility Artifacts in Magnetic Resonance Thermometry and Dosimetry for Monitoring Microwave Thermoablation: A Feasibility Study in a Swine Model

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Real‐time monitoring of microwave liver ablation (MWA) using MRI thermometry can be hindered by boiling‐induced susceptibility artifacts. These artifacts cause large temperature measurement errors that prevent accurate lesion size prediction.
