Simultaneous Acquisition of Diffusion Tensor and Dynamic Diffusion MRI.

ABSTRACT:

Background

Dynamic diffusion magnetic resonance imaging (ddMRI) metrics can assess transient microstructural alterations in tissue diffusivity but requires additional scan time hindering its clinical application.

Purpose

To determine whether a diffusion gradient table can simultaneously acquire data to estimate dynamic and diffusion tensor imaging (DTI) metrics.

Study type

Prospective.

Subjects

Seven healthy subjects, 39 epilepsy patients (15 female, 31 male, age ± 15).

Field strength/sequence

Two-dimensional diffusion MRI (b = 1000 s/mm² ) at a field strength of 3 T. Sessions in healthy subjects-standard ddMRI (30 directions), standard DTI (15 and 30 directions), and nested cubes scans (15 and 30 directions). Sessions in epilepsy patients-two
