Abstract

The measurement of the velocity of perfused flow in tissue in vivo is complicated by the presence of stationary as well as moving spins and by a variety of dephasing 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.

摘要

体内组织中灌注流速度的测量因存在静止和移动的自旋以及影响信号幅度的各种去相位现象而变得复杂。本文描述了一种技术，通过使用具有一组非常长回波时间（TE）的流动敏感自旋回波序列，可以评估移动成分的速度。
