I’m writing a review on spinal fMRI data processing (addressing reviewers comments), and I’m looking into the application of slice timing correction for spinal fMRI data. I revisited the following publications:
- Kong et al., https://www.pnas.org/content/111/50/18067
- Kong et al., https://www.sciencedirect.com/science/article/abs/pii/S1053811911013590?via%3Dihub
- Eippert et al. https://www.sciencedirect.com/science/article/abs/pii/S1053811916305420
- Barry et al. https://www.sciencedirect.com/science/article/abs/pii/S1053811916001671
- Stroman et al. https://pubmed.ncbi.nlm.nih.gov/16795083/
The Eippert/Kong articles thoroughly describe methods for incorporating slice-specific nuisance regressors (based on external pulseOx and respiratory signals), but I don’t find any mention of slice-timing correction for the underlying BOLD signal, for all the above articles.
The Barry et al. article looks at within-slice correlations, so I guess slice timing correction was not needed there, but in general, what is the recommended approach for slice-timing correction in spinal fMRI time series?
Any thoughts/references would be appreciated
