The fast-field-echo (FFE) sequence provides a new rapid imaging method for MR tomography. By using gradient echoes with shorter high frequency pulse repetitions than conventional sequences with 180 degrees echo pulses, it is possible to produce single cuts in 10 to 20 s with good signal-to-noise ratio. In this way the liver can be examined while respiratory movement artifacts are reduced. The possibility of obtaining T1- and T 2-weighted FFE images with good contrast resolution and the ability to determine relaxation times suggests a wide application of this rapid imaging procedure in the diagnosis of liver disease.
快速场回波（FFE）序列为磁共振断层成像提供了一种新的快速成像方法。通过使用比具有180度回波脉冲的传统序列更短的高频脉冲重复的梯度回波，可以在10至20秒内产生具有良好信噪比的单层图像。通过这种方式，可以在减少呼吸运动伪影的同时检查肝脏。获得具有良好对比度分辨率的T1加权和T2加权FFE图像以及确定弛豫时间的能力表明这种快速成像方法在肝脏疾病诊断中具有广泛的应用前景。
