The following data repositories are publicly available:
MRI data obtained in human volunteers (ArXiv, 14 November 2023)
“Fat-free noncontrast whole-heart CMR with fast and power-optimized off-resonant water excitation pulses“
DOI:
Code provided on GITHUB: Code to 1) read the 3D radial raw data and 2) to perform numerical RF pulse simulations.
Data provided on Zenodo: Volunteer data
- The repository contains whole-heart volunteer data obtained in 5 healthy subjects at 3T.
- In each subject, the acquisition was peformed with four different RF water excitation pulses: LIBOR (1.ms), BORR (1.0ms), LIBRE (1.0ms) and LIBRE (2.2ms).
- In addition, the repository contains 3D radial data acquired in knees of three healthy subjects to test the same four pulses.
