Abstract
Background: Significant advancements in neuroimaging have emerged over the past decade, notably through positron emission tomography (PET) and magnetic resonance imaging (MRI) for diagnosing Alzheimer's disease (AD) and its precursor, mild cognitive impairment (MCI). Combining imaging modalities with machine learning (ML) techniques enhances diagnostic accuracy.
Objective: To develop predictive models using pre-treatment brain imaging data to distinguish between normal controls (NC), MCI, and AD stages, improving diagnostic precision.
Methods: We utilized the Alzheimer's Disease Neuroimaging Initiative database, processing 3D MRI, PET Florbetaben, and PET Flortaucipir images. Techniques included convolutional neural networks (CNN), fuzzy logic, and multi-layer perceptron (MLP). Feature extraction involved amyloid-β volume, tau protein levels, and empty space volumes.
Results: The fuzzy logic approach achieved a classification accuracy of 99.1%, outperforming CNN (90.67%) and MLP (94%). Integration of multimodal data significantly enhanced performance compared to single-modality approaches.
Conclusions: Our study demonstrates that integrating advanced ML techniques with multimodal neuroimaging can effectively classify AD stages. These findings address critical gaps in early detection and provide a foundation for future clinical applications.
背景:在过去的十年中,神经影像学取得了重大进展,特别是通过正电子发射断层扫描(PET)和磁共振成像(MRI)诊断阿尔茨海默病(AD)及其前驱轻度认知障碍(MCI)。将成像模式与机器学习(ML)技术相结合可以提高诊断的准确性。目的:利用治疗前脑成像数据建立预测模型,以区分正常对照(NC)、MCI和AD分期,提高诊断精度。方法:我们利用阿尔茨海默病神经影像学倡议数据库,处理3D MRI, PET Florbetaben和PET Flortaucipir图像。技术包括卷积神经网络(CNN)、模糊逻辑和多层感知器(MLP)。特征提取涉及淀粉样蛋白-β体积、tau蛋白水平和空腔体积。结果:模糊逻辑方法的分类准确率达到99.1%,优于CNN(90.67%)和MLP(94%)。与单模态方法相比,多模态数据的集成显著提高了性能。结论:我们的研究表明,将先进的ML技术与多模态神经影像学相结合可以有效地分类AD的分期。这些发现解决了早期发现的关键空白,并为未来的临床应用奠定了基础。
