Fig. 5
Schematic of spinal cord gray matter volume analysis pipeline. Spinal cord preprocessing was performed using the Spinal Cord Toolbox. Images from a control participant were used to create the graphics for this figure. Panel A shows the PAM50 T2 -weighted template and the vertebral level masks. Panel B shows the template to T2-weighted structural image registration process. Panel C shows the process of segmenting the spinal cord gray matter. Gray matter volume (GMV) was extracted from the top of the C5 vertebra to the bottom of the C7 vertebra, and total horn GMVs were computed as left and right sums for each horn. D Dorsal, S Superior, V Ventral, R Right.
