Figure 2From: Respiratory effects on phase contrast imaging of the jugular veinMean flow over cardiac cycle for 5 volunteers in the dominant side IJV. While inspiration and expiration breath hold show minimal difference, the position 2 of both deep - and free - breathing show much higher mean flow than for position 1 indicating higher flow near the ‘inspiration plateau’. Likewise, the time averaged reconstruction gives mean flows somewhere in between positions 1 and 2.Back to article page
