It is important to perform visual inspection of spinal cord imaging data throughout an fMRI analysis pipeline. The method presented here is an extension of an existing technique developed for the brain, adapted to spinal cord fMRI. We create a two-dimensional heatmap of the spinal cord derived from four-dimensional imaging data, which can be co-visualized with traces of motion and physiological signals, and identify examples of structured variations in the heatmap that may be attributed to these nuisance signals. Implementing this visualization of spinal cord fMRI data is a simple and fast method to examine data quality.
