Conventions and nomenclature for double diffusion encoding NMR and MRI.
Stejskal and Tanner's ingenious pulsed field gradient design from 1965 has made diffusion NMR and MRI the mainstay of most studies seeking to resolve microstructural information in porous systems in general and biological systems in particular. Methods extending beyond Stejskal and Tanner's design, such as double diffusion encoding (DDE) NMR and MRI, may provide novel quantifiable metrics that ...
متن کاملComputational Diffusion MRI: Optimal Gradient Encoding Schemes
Diffusion-weighted magnetic resonance imaging (dMRI) is a non-invasive structural imaging technique that provides information about tissue micro-structures. Quantitative measures derived from dMRI reflect pathological and developmental changes in living tissues such as human brain. Such parameters are increasingly used in diagnostic and prognostic procedures and this has motivated several studi...
متن کاملAdapting the Kärger model to account for finite diffusion-encoding pulses in diffusion MRI
Diffusion magnetic resonance imaging (dMRI) is an imaging modality that probes the diffusion characteristics of a sample via the application of magnetic field gradient pulses. If the imaging voxel can be divided into different Gaussian diffusion compartments with inter-compartment exchange governed by linear kinetics, then the dMRI signal can be described by the Kärger model, which is a well-kn...
متن کاملDouble Oscillating Diffusion Encoding (DODE) augments microscopic anisotropy contrast
Target audience. Researchers and clinicians interested in the brain’s microarchitecture and diffusion MR methods. Purpose. Generating a methodology capable of amplifying Double-Diffusion-Encoding MR’s sensitivity towards randomly oriented compartments. Introduction. Double Diffusion Encoding (DDE, Fig. 1A) [1] NMR and MRI techniques – more commonly known as Double Wave Vector (DWV) [2] or doubl...
متن کاملDouble oscillating diffusion encoding and sensitivity to microscopic anisotropy
PURPOSE To introduce a novel diffusion pulse sequence, namely double oscillating diffusion encoding (DODE), and to investigate whether it adds sensitivity to microscopic diffusion anisotropy (µA) compared to the well-established double diffusion encoding (DDE) methodology. METHODS We simulate measurements from DODE and DDE sequences for different types of microstructures exhibiting restricted...
