中文摘要
我们在过去一年中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,重点是了解用OGSE-DWI测量时信号的渐近高频和低频极限。基于本文的结果,在名古屋举行的ISMRM日本分会会议(2022年9月10日至11日)上进行了演示。我们还扩展了使用OGSE-DWI测量ADC的工作。特别是,它已被证明,动态指数表征的全球组织的介质可能被系统地低估。这一事实将成为2023年6月在多伦多举行的ISMRM会议上发表演讲的核心成果。
英文摘要
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.
