Fast and robust deep learning tools for analysis of neuroimaging data of Alzheimer's disease

阿尔茨海默病(AD)是最常见的神经退行性疾病。临床前干预措施 而前驱阶段是减缓或阻止疾病进展的吸引人的目标。希望是这样的 对轻度认知障碍患者实现AD痴呆和认知功能减退的准确预后 增加了罹患AD的风险。为了实现AD痴呆的快速准确预后 基于神经成像数据，我们将开发和验证新的深度学习技术。尤其是，我们 将开发用于分割大脑图像和重建大脑皮层的无监督深度学习方法 来自结构磁共振成像数据的表面。这些快速而准确的图像处理 这些方法将结合先进的深度学习方法来建立AD的预测模型 使用大规模成像数据集的事件间隔时间分析框架中的痴呆症和认知能力下降。 最后，我们将开发和发布一个用户友好、开源、模块化和可扩展的软件 改善阿尔茨海默病预后的药包。源代码、独立程序和Web应用程序 所有算法的接口将在GitHub和NITRC上提供。我们的工具将支持实时 神经成像数据分析，可以在不同的领域找到应用，包括量化大脑变化 与衰老和发育有关的。

Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder. Interventions at the preclinical and prodromal stages are appealing targets for slowing or halting disease progression. It is desired to achieve accurate prognosis of AD dementia and cognitive decline for people with mild cognitive impairment who have increased risk to develop AD. In order to achieve fast and accurate prognosis of AD dementia based on neuroimaging data, we will develop and validate novel deep learning techniques. Particularly, we will develop unsupervised deep learning methods for segmenting brain images and reconstructing cortical surfaces from structural magnetic resonance imaging data. These fast and accurate image processing methods will be used in conjunction with advanced deep learning methods to build prognosis models of AD dementia and cognitive decline in a time-to-event analysis framework using large-scale imaging datasets. Finally, we will develop and disseminate a user friendly, open source, modular, and extensible software package to improve prognosis of AD dementia. Source code, standalone programs, and web-application interfaces of all the algorithms will be made available on GitHub and NITRC. Our tools will enable real-time neuroimaging data analysis and can find applications in diverse fields, including quantifying brain changes associated with aging and development.
