IMPLEMENTATION OF DIPOLAR MAGNETIZATION SEQUENCES AT 750MHZ

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。偶极磁化为磁共振成像提供了一种有趣的替代对比机制，在高场下，偶极回波可以大于初级自旋回波。本资源的一个目标是在750-MHz下实现这些序列并评估它们的效用。这些序列已经在600和750 MHz的仪器（以及诺丁汉的400 MHz）上实现，显示出高场达到时的非线性行为。这也是Core 2的研究重点。简而言之，这是迄今为止研究过的最高的领域mse。此外，我们已经能够在更长的距离尺度上模拟非线性信号的行为。

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.
