Measurement of flow using a complex difference method of magnetic resonance imaging

NMR image data is acquired with velocity encoding gradients applied and both a phase difference image array and a complex difference image array are produced. A flow image is produced from the complex difference image array after it is corrected for spin saturation effects and calibrated using infor...
