Diffusion MRI Data for Kurtosis Imaging Evaluation in Neural Tissue and Phantom

Diffusion MRI data from fixed rat brain and spinal cord, normal human brain, and a physical phantom was acquired for evaluating diffusion kurtosis imaging contrasts and optimizing b-values. The dataset, authored by Brian Hansen and released in 2020, includes acquisitions from 9.4T, 16.4T, and 3T scanners. It supports exploration of diffusion parameter contrasts and kurtosis fractional anisotropy.

Use Cases

• Evaluate diffusion kurtosis imaging (DKI) parameter contrasts against diffusion tensor imaging (DTI) using data from rat brain and spinal cord.
• Optimize b-values for fast kurtosis imaging protocols based on ex vivo and in vivo dMRI data from 9.4T, 16.4T, and 3T scanners.
• Explore kurtosis fractional anisotropy using dMRI data from a physical phantom with three orthogonal fiber orientations.
• Simulate image contrast for a range of dMRI analysis strategies using combined data from biological tissue and a physical phantom.

Strengths

• Includes dMRI data from multiple scanner field strengths (3T, 9.4T, 16.4T), enabling field strength comparisons.
• Covers diverse sample types: fixed rat brain, rat spinal cord, normal human brain, and a physical phantom.
• Data was used for recent methodological evaluations in diffusion kurtosis imaging and b-value optimization.

Limitations

• Sample size and specific scan parameters are not provided, limiting reproducibility of analyses.
• Data is from 2020 and may not reflect the latest dMRI acquisition or reconstruction techniques.
• Lack of detailed column or file structure information requires manual inspection before use.
