Fig. 2From: Characterising spinal cerebrospinal fluid flow in the pig with phase-contrast magnetic resonance imagingCSF flow over one cardiac cycle from PC-MRI data (n = 9). The red line is CSF flow in the dorsal SAS and the blue line is CSF flow in the ventral SAS. Solid lines are mean, and shaded region is ± one SD. Negative CSF flow is in the caudal direction (systolic flow).
