Scalable spokes pTx pulses for 2D turbo‐spin‐echo imaging at 7 T

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Turbo spin echo (TSE) is important clinically. Unfortunately, 7 T TSE suffers from B1+‐induced signal dropouts. Magnitude‐based parallel transmit (pTx) pulse design algorithms cannot enforce phase patterns complying with the Carr‐Purcell‐Meiboom‐Gill conditions (90° phase shift between excitation and refocusing).

Simultaneous in vivo detection of spectrally resolved glutamate, glutamine, and glutathione at 3 T with NAA‐aspartyl editing and echo‐time optimization

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To achieve spectrally resolved in vivo detection of glutamate, glutamine, and glutathione at 3 T. Methods Difference editing of N‐acetylaspartate CH2 protons (NAA‐CH2) combined with a new echo‐time (TE) optimization approach is introduced.

T1‐weighted fMRI in mouse visual cortex using an iron oxide nanoparticle contrast agent and UTE imaging at 9.4 T

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose This study aims to investigate the feasibility of using T1‐weighted fMRI with an iron oxide nanoparticle contrast agent and UTE imaging at 9.4 T to measure functional hyperemia in the mouse visual cortex. The goal is to capture positive signal changes in both the parenchyma and pial surface, and to test whether surface vessels respond ...

Dynamic Transitions for Fast Joint Acquisition and Reconstruction of CEST‐Rex$$ {R}_{ex} $$ and T1$$ {T}_1 $$

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This work proposes a method for the simultaneous estimation of the exchange‐dependent relaxation rate Rex$$ {R}_{ex} $$ and the longitudinal relaxation time T1$$ {T}_1 $$ from a single acquisition. Methods A novel acquisition scheme was developed that combines CEST saturation with an inversion pulse and a Look‐Locker readout to capture

Image‐Based Flaw Identification Using Convolutional Neural Network

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Flaw detection in structures is crucial for ensuring structural integrity and safety across various engineering applications. Traditional nondestructive evaluation (NDE) techniques often face challenges in accurately identifying and characterizing flaws, particularly when dealing with complex geometries and strain fields.
