IMPLEMENTATION OF DIPOLAR MAGNETIZATION SEQUENCES AT 750MHZ

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。偶极磁化为MR提供了一种有趣的替代对比机制。在高场下，偶极回波可以比主自旋回波更大。该资源的一个目标是在750-MHz上实现这些序列并评估它们的实用性。这些序列已经在600 MHz和750 MHz仪器上实现(在诺丁汉的400 MHz仪器上)，显示了当达到高场时的非线性行为。这已成为上面针对Core 2的研究重点。简而言之，这些是迄今研究过的最高领域的MSE。此外，我们已经能够在更长的距离尺度上对非线性信号行为进行建模。

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.
