A new method for the measurement of blood flow using magnetic resonance imaging has been developed. The flow velocities are calculated from the distances that the fluid has moved. The distances are directly visualized by a new pulse sequence. In a phantom study, the measured flow rates showed very good correlation with actual flow rates of up to 20 l/min (3 m/sec). In a volunteer study, pulsatile flow velocities of a large artery were measured with electrocardiographic gating. The flow pattern of a cardiac cycle at the abdominal aorta is similar to that revealed by other methods of measurement, such as Doppler ultrasound. This method allows reasonably accurate quantitative analysis of blood flow in the large arteries.
一种利用磁共振成像测量血流的新方法已被开发出来。流速是根据流体移动的距离计算得出的。这些距离通过一种新的脉冲序列直接可视化。在体模研究中，测量的流速与高达20升/分钟（3米/秒）的实际流速显示出非常好的相关性。在志愿者研究中，通过心电图门控测量了一条大动脉的搏动流速。腹主动脉心动周期的血流模式与其他测量方法（如多普勒超声）所显示的相似。这种方法能够对大动脉中的血流进行合理准确的定量分析。
