MR imaging of flow using the steady state selective saturation method

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.
