The diagnostic value of a fast multislice gradient-echo sequence was compared with that of conventional spin-echo sequences in a prospective study of 76 patients. With the multislice gradient-echo sequence, the entire liver can be examined in less than 3 minutes since five sections can be imaged during one breath-holding period. The strongly T1-weighted gradient-echo sequence (GRE 100/5/80 degrees) yields a significantly better T1-contrast than the T1-weighted spin-echo sequence (SE 500/15) (p less than 0.01) and thus improves the visualization of liver lesions. Another major advantage of the fast gradient-echo sequence is the pronounced reduction of motion artefacts.
在一项针对76例患者的前瞻性研究中，对快速多层梯度回波序列与传统自旋回波序列的诊断价值进行了比较。使用多层梯度回波序列，由于在一次屏气期间可以成像五个层面，因此整个肝脏能够在不到3分钟的时间内完成检查。强T1加权梯度回波序列（GRE 100/5/80°）产生的T1对比度明显优于T1加权自旋回波序列（SE 500/15）（p<0.01），从而改善了肝脏病变的可视化效果。快速梯度回波序列的另一个主要优点是运动伪影明显减少。
