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资助的中心赠款提供的资源的许多研究子项目之一。子弹和调查员（PI）可能已经从其他NIH来源获得了主要资金，因此可以在其他清晰的条目中代表。列出的机构适用于该中心，这不一定是调查员的机构。偶极磁化为MR提供了有趣的替代对比机制。在高场，偶极回声可能大于主自旋回波。资源的目标是以750 MHz实施这些序列并评估其效用。这些序列已在600和750 MHz仪器（和诺丁汉的400 MHz）上实现，显示出非线性行为，因为达到了高场。这已成为上述核心2的研究亮点。简而言之，这些是尚未检查的最高现场MSE。此外，我们还能够在较长距离尺度上对非线性信号行为进行建模。
