Abstract
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 information derived from the phase difference image array. Total blood flow through vessels can be measured from the flow image.
