Some implementations provide a method for imaging one or more peripheral nerves in a region of a subject, which method includes: introducing a dose of an iron-based agent into the subject, wherein the dose causes a reduction of a T2 relaxation time of the subject's blood; and acquiring, from a magnetic resonance imaging (MRI) scanner, one or more fluid-sensitive MRI images of the region of the subject that has received the dose. The magnetic resonance (MR) signals from the subjects blood in the region is substantially reduced in response to the dose of the iron-based agent.

A computer-implemented method includes: generating a set of simulated diffusion signals based on a corresponding set of diffusion sampling parameters and a corresponding set of micro structural model parameters, wherein the diffusion sample parameters correspond to magnetic resonance (MR) parameters, and wherein the microstructural model parameters characterizing a microscopic diffusion with a spatial orientation; processing the set of simulated diffusion signals based on the corresponding set of diffusion sampling parameters to generate a first set of output metrics, wherein the first set of output metrics are associated with the spatial orientation; consolidating multiple sets of output metrics into a dictionary, wherein each set of the multiple sets of output metrics are generated by processing a corresponding set of simulated diffusion signals and associated with a corresponding spatial orientation; applying the dictionary to a set of acquired diffusion MR signals; and generating at least one macroscopic diffusion feature that is orientation invariant.

System and apparatus for simplified diffusion imaging fitting using a rotational invariant dictionary

A computer-implemented method for suppressing fat in reconstructed magnetic resonance imaging data includes generating, via a processor, a first echo image and a second echo image from magnetic resonance scan data acquired of a subject with a magnetic resonance scanner utilizing a multi-echo steady state sequence. The computer-implemented method also includes estimating, via the processor, an echo phase difference between the first echo image and the second echo image to generate an echo phase difference image. The computer-implemented method further includes identifying, via the processor, voxels in the echo phase difference image having an extra chemical shift phase. The computer-implemented method even further includes removing, via the processor, signals of the voxels identified having the extra chemical shift phase in both the first echo image and the second echo image to generate a first fat-removed image and a second fat-removed image, respectively.
