提出了一种用于磁共振互补空间磁化调制(CSPAMM)标记的有效脂肪抑制方法。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,在图像重建期间,所采集图像的减影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,所提出的方法允许成像具有更高的时间分辨率和更短的回波时间,而不增加扫描时间。使用MR体模和人类志愿者测试了在1.5特斯拉(T)和3.0T扫描仪上应用该方法的可行性。Magn Reson Med 61:234-238,2009. (C)2008 Wiley-Liss,Inc.
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. Magn Reson Med 61: 234-238, 2009. (C) 2008 Wiley-Liss, Inc.
