Development of a technique to noninvasively study the structure of in vivo vasculature in rodent brain using oscillating-gradient spin-echo diffusion-weighted magnetic resonance imaging

在过去的一年里，我们的努力包括继续修订和其他活动，以出版我们的第二份手稿，其重点是理解用OGSE-DWI测量时信号的渐近高频和低频极限。根据这篇论文的结果，在2022年9月10日至11日在名古屋举行的ISMRM日本分会会议上进行了介绍。我们还扩展了OGSE-DWI测量ADC的工作。特别是，已经证明表征介质的全球组织的动态指数可能被系统地低估了。这一事实将成为2023年6月在多伦多举行的ISMRM会议上发表的一份报告的核心结果。

Our efforts over the past year include continued revision and other activity towards the publication of our second manuscript, which focusses on understanding the asymptotic high- and low-frequency limits of the signal when measured with OGSE-DWI. Based on the results in this manuscript a presentation was made at the ISMRM Japan Chapter meeting in Nagoya (Sept 10-11, 2022).We have also extended our work on the ADC measured with OGSE-DWI. In particular, it has been demonstrated that the dynamic exponent characterising the global organisation of a medium may be systematically underestimated. This fact will be the core result in a presentation to be made at the ISMRM conference in Toronto in June 2023.
