FlexCENT: A frequency-flexible CEST imaging network combining frequency offset encoding and three-dimensional U-Net

This study proposes a deep learning-based method termed frequency-flexible chemical exchange saturation transfer (CEST) imaging network (FlexCENT), which enables robust CEST quantification across variable...

Mean pore diameters of 3D printed micro-capillaries using the matrix pencil method

The matrix pencil method (MPM) is an approach for quantitative analysis of the multi-exponential time-domain signals from relaxation and diffusion NMR experiments. In contrast to other signal processing...

Spin-echo measurements for capillary rheometry at low field

A single spin-echo, acquired in the presence of a constant magnetic field gradient, has a phase proportional to the average velocity of the sample and an amplitude determined by the distribution of...

Passive water exchange between multiple sites can explain why apparent exchange rate constants depend on ionic and osmotic conditions in gray matter

Porous materials, such as biological tissue, often have heterogeneous microstructures where imbibed fluid experiences distinct environments on short timescales, but can exchange among different environments...

Exploring the effect of ethanol-water structuring on the transport properties of ethanol in porous silicas

The transport properties of liquid mixtures confined within porous media can change significantly from those observed for bulk mixtures due to changes in the liquid structuring within the pore space....

Self-supervised pre-training based hybrid network for deep gray matter nuclei segmentation

The accurate segmentation of deep gray matter nuclei is critical for neuropathological research, disease diagnosis and treatment. Existing methods employ the supervised learning training approach, which...

SNMR with short pulses: Optimizing the kernel calculation by considering the influence of pulse shape and phase

In the past few years, efforts have been made to extend the sensitivity of surface nuclear magnetic resonance (SNMR) to short relaxation times, typical for strongly bound water, which, for example,...
