双脉冲回波——磁共振成像中脂肪-水分离的一种新方法。

Magn Reson Med. 1986 Aug;3(4):639-43. doi: 10.1002/mrm.1910030417.

A novel method to obtain separate fat and water images is presented. It is based on the replacement of the first echo generating pi pulse by two pi/2 pulses separated by a time delay corresponding to one-half cycle of the resonance frequency difference between fat and water protons.

提出了一种获取单独的脂肪和水图像的新方法。它基于用两个间隔为一个时间延迟的π/2脉冲取代产生π脉冲的第一个回波，该时间延迟对应于脂肪和水质子之间共振频率差的半个周期。
