a: The blood flow rate in the popliteal artery of a normal volunteer is measured with conventional gated-segment PC-MRI (solid line). Several heartbeats of blood flow in the same artery are measured with the real-time complex-difference method (dashed lines) for a direct comparison of the two techniques. A single complete cardiac cycle is displayed. b: The blood flow rate in the infrarenal aorta of a normal volunteer is measured with conventional gated-segment PC-MRI (solid line). Several heartbeats of blood flow in the same artery are measured with the real-time complex-difference method (dashed lines) for a direct comparison of the two techniques. A single complete cardiac cycle is displayed.
