An efficient fat suppression method is presented for MR tagging with complementary spatial modulation of magnetization (CSPAMM). In this method, the complementary modulation is applied to the water content of the tissues, while in-phase modulation is applied to the fat content. Therefore, during image reconstruction, the subtraction of the acquired images increases the tagging contrast of the water while cancels the tagging lines of the fat. Compared with the existing fat suppression techniques, the proposed method allows imaging with higher temporal resolution and shorter echo-time without increasing the scan time. The feasibility of applying the method on 1.5 Tesla (T) and 3.0T scanners has been tested using MR phantom and human volunteers.
提出了一种用于磁共振标记的高效脂肪抑制方法，即互补磁化空间调制（CSPAMM）。在该方法中，互补调制应用于组织的水含量，而同相调制应用于脂肪含量。因此，在图像重建过程中，采集图像的相减增加了水的标记对比度，同时消除了脂肪的标记线。与现有的脂肪抑制技术相比，该方法允许在不增加扫描时间的情况下以更高的时间分辨率和更短的回波时间进行成像。已使用磁共振体模和人体志愿者测试了该方法在1.5特斯拉（T）和3.0T扫描仪上应用的可行性。
