讲座内容简介

(中文)

大脑微结构的定量成像对脑发育和脑疾病研究都至关重要。在努力发展新型快速定量成像技术的同时,影像标志物的有效性和可重复性是当下多中心、大队列研究背景下的热点话题。近年来,我们关注扩散磁共振成像的神经病理学基础,建立了一套稳定的离体人脑标本的全/半脑磁共振成像规范方案,获得高质量高分辨率的离体人脑形态、结构等图像;其次,我们从成像物理和校正方法两个角度研究跨中心扩散成像的异质性因素,设计了可操作的质控方法和基于深度学习方法的数据融合方法,并公开发布了高质量的多中心扩散成像的旅行志愿者公开数据集。这些工作提示改进采集和分析方法可以有效地提高定量磁共振成像队列研究的准确性和可靠性。

讲座内容简介

(英文)

Quantitative imaging of brain   microstructure is essential for brain development and brain disease research.   While striving to develop new rapid quantitative imaging technologies, the   validity and reproducibility of image markers are currently hot topics in the   context of multi-center and large cohort research. In recent years, we have   paid attention to the neuropathological basis of diffusion magnetic resonance   imaging, and established a set of stable whole/half brain magnetic resonance   imaging specifications of isolated human brain specimens, and obtained   high-quality and high-resolution isolated human brain morphology and   structure. Second, we studied the heterogeneity factors of cross-center   diffusion imaging from the perspectives of imaging physics and correction   methods, designed operational quality control methods and data fusion methods   based on deep learning methods, and publicly released high-quality A public   dataset of traveling volunteers for multicenter diffusion imaging. These work   suggest that improving acquisition and analysis methods can effectively   improve the accuracy and reliability of quantitative magnetic resonance   imaging cohort studies.
