This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Dipolar magnetization offers an interesting alternative contrast mechanism for MR. At high field, the Dipolar echoes can be larger than the primary spin echo. A goal of the Resource is to implement these sequences at 750-MHz and evaluate their utility. These sequences have been implemented on both the 600 and 750 MHz instruments (and 400 MHz at Nottingham), demonstrating non-linear behavior as high fields are reached. This has been made the research highlight above for Core 2. In short, these are the highest field MSEs yet examined. Additionally, we have been able to model the non-linear signal behavior at longer distance scales.

该子项目是利用 NIH/NCRR 资助的中心拨款提供的资源的众多研究子项目之一。子项目和研究者 (PI) 可能已从另一个 NIH 来源获得主要资金，因此可以在其他 CRISP 条目中得到体现。列出的机构是中心的机构，不一定是研究者的机构。偶极磁化为 MR 提供了一种有趣的替代对比机制。在高场下，偶极回波可能大于主自旋回波。该资源的目标是在 750 MHz 下实现这些序列并评估其效用。这些序列已在 600 和 750 MHz 仪器（以及诺丁汉的 400 MHz）上实现，展示了达到高场时的非线性行为。这已成为上述 Core 2 的研究重点。简而言之，这些是迄今为止检查过的最高的现场 MSE。此外，我们已经能够在较长距离尺度上对非线性信号行为进行建模。
