Optimizing Filter-Probe Diffusion Weighting in the Rat Spinal Cord for Human Translation [PDF]

open access: yes, 2017
Diffusion tensor imaging (DTI) is a promising biomarker of spinal cord injury (SCI). In the acute aftermath, DTI in SCI animal models consistently demonstrates high sensitivity and prognostic performance, yet translation of DTI to acute human SCI has ...

Pore size estimation from double diffusion encoding

open access: yesCurrent Directions in Biomedical Engineering, 2017
Double diffusion encoding is a magnetic resonance technique with applications in measuring microstructure. In many tissues, cell size (which is of a few micrometers) is an important biological parameter.

Mini Review on Anomalous Diffusion by MRI: Potential Advantages, Pitfalls, Limitations, Nomenclature, and Correct Interpretation of Literature

open access: yesFrontiers in Physics, 2020
In this mini-review, we addressed the transient-anomalous diffusion by MRI, starting from the assumption that transient-anomalous diffusion is ubiquitously observed in biological tissues, as demonstrated by different single-particle-tracking optical ...

Diffusion tensor model links to neurite orientation dispersion and density imaging at high b-value in cerebral cortical gray matter [PDF]

open access: yes, 2019
Diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) are widely used models to infer microstructural features in the brain from diffusion-weighted MRI. Several studies have recently applied both models to increase

The arcuate fasciculus network and verbal deficits in psychosis

open access: yesTranslational Neuroscience, 2017
Verbal learning (VL) and fluency (VF) are prominent cognitive deficits in psychosis, of which the precise neuroanatomical contributions are not fully understood.

Dissipative effects on the sustainment of a magnetorotational dynamo in Keplerian shear flow [PDF]

open access: yes, 2014
The magnetorotational (MRI) dynamo has long been considered one of the possible drivers of turbulent angular momentum transport in astrophysical accretion disks.

Correlation between ultrasound-guided percutaneous breast biopsy and diffusion-weighted magnetic resonance imaging of the breast for evaluation of solid breast lesions

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2020
Background MRI’s role had been increasing in breast imaging. In this study, we evaluated the role of diffusion-weighted MRI in correlation with ultrasound-guided percutaneous breast biopsy for diagnosis of solid breast lesions.

Optimization of diffusion imaging for multiple target regions using maximum likelihood estimation

open access: yesCurrent Directions in Biomedical Engineering, 2017
In this work a procedure is proposed to determine an optimal distribution of b-values in diffusion MRI measu-rements. The optimization procedure uses a method of Maximum Likelihood Estimation which can operate on any given number of b-values, values of ...
