From: Technique for retrospective respiratory and cardiac-gated phase contrast flow measurements
– CSF flow through the spinal cord for two volunteers during deep breathing. Three curves are shown for each volunteer, all measured from the same acquisition. Each chart depicts the flow from the respiratory phase surrounding inspiration (red) and expiration (blue) as well as the average flow measured without respiratory binning (black). Note the increase in flow in the inspiration phase, which corresponds to a decrease in thoracic pressure.
