Further improvement of high-speed NMR flow-velocity measurement using a differential phase-encoding technique

An NMR imaging technique applicable to high‐velocity flow imaging is described. By subtraction of two phase images obtained by varying the flow‐encoding gradient, it is possible to extract much larger ranges of velocity components. This differential phase‐encoding technique is tested by experiments...

Zusammenfassung:An NMR imaging technique applicable to high‐velocity flow imaging is described. By subtraction of two phase images obtained by varying the flow‐encoding gradient, it is possible to extract much larger ranges of velocity components. This differential phase‐encoding technique is tested by experiments in a phantom as well as a human volunteer. © 1987 Academic Press, Inc.
