We present our initial experience with the use of a modified 3-point Dixon technique to obtain reliable fast spin-echo T1- and T2-weighted fat-suppressed images in the soft-tissue neck. The method has less sensitivity to magnetic field inhomogeneity than frequency-selective radiofrequency fat saturation and provides uniform fat suppression even near tissue-tissue and air-tissue interfaces. Clinical advantages and limitations of the method are discussed and several examples are shown.
我们介绍了使用改良的三点 Dixon 技术在颈部软组织中获取可靠的快速自旋回波 T1 加权和 T2 加权脂肪抑制图像的初步经验。该方法对磁场不均匀性的敏感度低于频率选择性射频脂肪饱和法,并且即使在组织 - 组织和空气 - 组织界面附近也能提供均匀的脂肪抑制。文中讨论了该方法的临床优势和局限性,并展示了几个示例。
