Purpose: To test the hypothesis that correlation time diffusion coefficient (DCT) MRI is not be dependent of the main magnetic field strength B0. Methods: A heathy volunteer was scanned (head) at 1.5T and 3.0T with the same diffusion mapping capable scans: quadra-FSE for DCT mapping and DW-SE-sshEPI for DPFG mapping. Results: Despite the B0 dependent shifts of the relaxation time (T1, T2) histograms, the DCT, DPFG, and PD histograms do not exhibited significant B0 shifts. Conclusion: The correlation time diffusion coefficient is theoretically and experimentally a genuine physical property inherent to biological tissue and independent of experimental variables including B0.
