講座內(nèi)容簡(jiǎn)介 (中文) | 大腦微結(jié)構(gòu)的定量成像對(duì)腦發(fā)育和腦疾病研究都至關(guān)重要。在努力發(fā)展新型快速定量成像技術(shù)的同時(shí),影像標(biāo)志物的有效性和可重復(fù)性是當(dāng)下多中心、大隊(duì)列研究背景下的熱點(diǎn)話題。近年來(lái),我們關(guān)注擴(kuò)散磁共振成像的神經(jīng)病理學(xué)基礎(chǔ),建立了一套穩(wěn)定的離體人腦標(biāo)本的全/半腦磁共振成像規(guī)范方案,獲得高質(zhì)量高分辨率的離體人腦形態(tài)、結(jié)構(gòu)等圖像;其次,我們從成像物理和校正方法兩個(gè)角度研究跨中心擴(kuò)散成像的異質(zhì)性因素,設(shè)計(jì)了可操作的質(zhì)控方法和基于深度學(xué)習(xí)方法的數(shù)據(jù)融合方法,并公開發(fā)布了高質(zhì)量的多中心擴(kuò)散成像的旅行志愿者公開數(shù)據(jù)集。這些工作提示改進(jìn)采集和分析方法可以有效地提高定量磁共振成像隊(duì)列研究的準(zhǔn)確性和可靠性。 |
講座內(nèi)容簡(jiǎn)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.
