The steady state selective saturation method is a fast and efficient technique to study flow with magnetic resonance imaging. The pulse sequence used generates no signal from stationary matter and simultaneously optimizes signal flowing into a predetermined volume. The method can be used to generate three-dimensional angiography in less than 5 min. Other modifications allow the quantitative measurement of flow velocities and distinction of veins and arteries according to the direction of flow.
稳态选择性饱和法是一种利用磁共振成像研究血流的快速高效技术。所使用的脉冲序列不会从静止物质产生信号，同时能优化流入预定容积的信号。该方法可在不到5分钟的时间内生成三维血管造影。其他改进方法可实现血流速度的定量测量，并根据血流方向区分静脉和动脉。
