We investigated the impact of systematic errors on DTI metrics of an isotropic phantom and DTI metrics and tractography of a rat brain measured at high resolution. We tested denoising and Gibbs ringing removal methods combined with the B matrix spatial distribution (BSD) method for magnetic field gradient calibration.

Developed and tested b spatial Distribution DTI technique ( BSD DTI) is a technique of calibration of b space, based on diffusion gradient correction in all directions used, made with application of well - defined structure of isotropic ( water ) and anisotropic ( capillary) phantom.

Abstract— The b-matrix spatial distribution (BSD) is an effective method of improving accuracy of diffusion tensor imaging (DTI) measurements. It is based on a calibration with an anisotropic phantom measured in six positions inside an MRI scanner.

Feb 1, 2017 · The BSD-DTI (B-matrix spatial distribution in DTI) is an alternative method of determining the exact form of the B-matrix. The actual values of the matrix in a particular region of interest (ROI) are derived experimentally with the use of an anisotropic phantom with a well-defined structure.

A novel method of improving accuracy of diffusion tensor imaging (DTI), called BSD-DTI (B-spatial distribution in DTI), has been recently proposed. Determination of the b matrix components using an anisotropic phantom, and derivation of the spatial distribution are …

The website enables obtaining DTI metrics for a given ROI according to the standard procedure STD and BSD-DTI, i.e. after taking into account systematic errors related to spatially non-uniform magnetic field gradients.

Introduction: Diffusion Tensor Imaging (DTI) quantitative metrics, such as Fractional Anisotropy (FA) and Mean Diffusivity (MD), offer objective measurements that are crucial for detecting and understanding pathological changes in the brain’s microstructure.

Nov 1, 2018 · The BSD-DTI technique allows to correct not only the magnitude, but also the direction of the diffusion gradient, what is crucial for accurate fiber tracking.

Apr 1, 2015 · A novel BSD-DTI method for improving the accuracy of diffusion tensor imaging was described. It takes into account the b matrix spatial variations, which can be determined using a carefully calibrated anisotropic diffusion phantom.

A novel method of improving accuracy of diffusion tensor imaging (DTI), called BSD-DTI (B-spatial distribution in DTI), has been recently proposed. Determination of the b matrix components using an anisotropic phantom, and derivation of the spatial distribution are …
