Use of ultralong echo time imaging to assist in measuring the velocity of perfused flowin vivo

Abstract
The measurement of the velocity of perfused flow in tissue in vivo is complicated by the presence ofstationary as well as moving spins and by a variety ofdephasing phenomena which affect signal amplitudes. This paper describes a technique by which, using flow‐sensitized spin‐echo sequences with a set of very long TE times, the velocity of the moving component can be assessed. © 1989 Academic Press, Inc.
