Pipeline: Advanced Diffusion Preprocessing Pipeline
Type: DTI
Description: Advanced diffusion preprocessing pipeline which includes enhanced denoising, B0 distortion corrections and tensor creation.
Source: Department of Radiology
External Link: Advanced Diffusion Preprocessing Pipeline
Details:
The Advanced Diffusion Preprocessing Pipeline incorporates advanced features such including the following:
Accepts Single scans, Multiple concatenated scans and Paired (Opposite Phase Encoding) diffusion scans
Advanced Denoising Algorithms
Manual filtering of bad directions prior to tensor calculation
Correcting gradient flip errors in the Dicom to NIFTI conversion process
B0 distortion correction
Improved Eddy Current Correction which minimizes distortions, rotates b-vectors, and improves spatial resolution
Improved warping to MNI space
The pipeline produces FA, MD, RD, AD, Trace, as well as Eigenvectors and Eigenvalues. Tensor files are also created using shells within the linear regime (b < 1600). Distortion/eddy current corrected files can also be used for NODDI analysis.
