The Potential for Absolute Temperature Imaging Based on Brain Metabolites Using an FID‐Shifting Approach in Gradient Echo Planar Spectroscopic Imaging (GREPSI)

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To implement and evaluate an efficient method for absolute temperature measurement using a gradient echo implementation of the echo planar spectroscopic imaging (EPSI) sequence. Methods The gradient echo EPSI sequence (GREPSI) utilizes an oscillating readout gradient together with continuous signal readout after slab selective ...

Multi‐Contrast Human Brain CEST MRI at 11.7 T: First In Vivo Demonstration

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT PurposeTo implement and evaluate chemical exchange saturation transfer (CEST) at ultra‐high field on a whole‐body 11.7 T scanner using parallel transmission (pTx). MethodsTailored pTx CEST saturation pulses were optimized to achieve a spatially uniform target B1+ while satisfying SAR and power constraints either defined by conservatively ...

Feasibility and SNR Performance of Hyperpolarized 129Xe Gas Exchange Imaging Using a Balanced SSFP Sequence

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a balanced SSFP (bSSFP) sequence for pulmonary 129Xe dissolved‐phase imaging based on a previously described double‐echo sequence facilitating separation into red blood cell and membrane signals, to test its feasibility and compare its SNR performance and imaging results to an analogous FLASH sequence.

A Review of Mechanical Reinforcement and Piezoresistive Self‐Sensing in Carbon Nanotube Fiber Composites

Polymer Composites, EarlyView.
PSPP‐TRL mapping of CNT‐modified CFRP literature, with four recurring confusions resolved and five scale‐up problems quantified. ABSTRACT Carbon nanotube‐modified fiber composites are often presented as a route to stronger, tougher, and self‐sensing structural materials.
