We propose an adaptation of the MISSTEC sequence (simultaneous acquisition of a spin echo and several stimulated echoes) for performing fat suppression with a three-point Dixon method. In vivo measurements were performed on healthy volunteers using a sequence of three echoes (one spin echo and two stimulated echoes) within a third of the acquisition time taken by the regular three-point method, with the same spatial resolution and with half the signal-to-noise ratio (SNR). Homogeneity of fat suppression was greatly increased in comparison with the two-point method.
我们提出了一种对MISSTEC序列(同时采集一个自旋回波和多个受激回波)的改编方法,用于采用三点 Dixon 法进行脂肪抑制。在健康志愿者身上进行了体内测量,使用由三个回波(一个自旋回波和两个受激回波)组成的序列,其采集时间为常规三点法的三分之一,具有相同的空间分辨率,且信噪比为常规三点法的一半。与两点法相比,脂肪抑制的均匀性有了显著提高。
