Abstract

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.

摘要

描述了一种适用于高速血流成像的核磁共振成像技术。通过减去改变流动编码梯度所获得的两幅相位图像，可以提取更大范围的速度分量。这种差分相位编码技术在体模以及人体志愿者身上进行了实验测试。
