Magnetic Resonance Imaging (MRI) systems using very strong magnetic fields that are greater than eighty thousand times the Earth's field are becoming increasingly available. These MRI systems are much stronger than standard clinical MRI systems that are at a field strength of 3.0 Tesla or lower. However, these higher field MRI systems still lack an adequate array of imaging methods for human imaging. New methods are needed to overcome the specific challenges of high field MRI. We will introduce new MRI methods for human brain imaging. Our work will provide insight into technical MRI and release new means to exploit inherent MRI contrast at both standard and high magnetic fields.

使用比地球磁场强八万倍的强磁场的磁共振成像 (MRI) 系统正变得越来越可用。 这些 MRI 系统比场强为 3.0 特斯拉或更低的标准临床 MRI 系统强得多。 然而，这些高场 MRI 系统仍然缺乏足够的人体成像成像方法。 需要新的方法来克服高场 MRI 的具体挑战。 我们将介绍用于人脑成像的新 MRI 方法。 我们的工作将提供对技术 MRI 的深入了解，并发布在标准磁场和高磁场下利用固有 MRI 对比度的新方法。
