4 Fig 3 Infrarenal (IR) flow waveforms, spinal cord injury (SCI) vs control. Phase-contrast magnetic resonance imaging data were acquired for each subject at an IR slice plane perpendicular to the aorta and processed to compare the flow waveform over one cardiac cycle.

5 Fig 4 Pressure and flow waveforms from representative spinal cord injury (SCI) (top) and control (bottom) subjects. Journal of Vascular Surgery  , e1DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

6 Fig 5 Infrarenal (IR) flow and pressure waveforms, spinal cord injury (SCI) vs control. Flow and pressure waveforms at the level of the infrarenal aorta were calculated from one-dimensional simulations.
