本研究提出MIMD-3DVT方法,通过多输入和混合数据提升阿尔茨海默病分类准确率至97.14%

摘要:

当前利用磁共振成像(MRI)诊断阿尔茨海默病的方法存在显著局限性。许多先前研究使用2D变换器独立分析单个脑切片,可能丢失关键的3D上下文信息。基于感兴趣区域的模型尽管阿尔茨海默病影响多个区域,却往往只关注少数几个脑区。此外,大多数分类模型依赖单一测试,而诊断阿尔茨海默病需要多方面的综合方法,整合多种数据源以获得更准确的评估。本研究提出了一种新的方法,称为多输入和混合数据3D视觉变换器(MIMD-3DVT)。该方法处理连续切片以捕捉特征维度和空间信息,融合多个3D感兴趣区域成像数据输入,并整合来自人口学因素、认知评估和脑成像的混合数据。所提出的方法在结合了阿尔茨海默病神经影像学倡议(ADNI)、澳大利亚成像、生物标志物和生活方式老龄化旗舰研究(AIBL)和开放获取影像研究系列(OASIS)的综合数据集上进行了实验评估。我们的MIMD-3DVT利用单个或多个感兴趣区域,实现了97.14%的准确率,优于现有最先进方法,在区分正常认知和阿尔茨海默病方面表现更佳。

英文摘要:

The current methods for diagnosing Alzheimer Disease using Magnetic Resonance Imaging (MRI) have significant limitations. Many previous studies used 2D Transformers to analyze individual brain slices independently, potentially losing critical 3D contextual information. Region of interest-based models often focus on only a few brain regions despite Alzheimer's affecting multiple areas. Additionally, most classification models rely on a single test, whereas diagnosing Alzheimer's requires a multifaceted approach integrating diverse data sources for a more accurate assessment. This study introduces a novel methodology called the Multiple Inputs and Mixed Data 3D Vision Transformer (MIMD-3DVT). This method processes consecutive slices together to capture the feature dimensions and spatial information, fuses multiple 3D ROI imaging data inputs, and integrates mixed data from demographic factors, cognitive assessments, and brain imaging. The proposed methodology was experimentally evaluated using a combined dataset that included the Alzheimer's Disease Neuroimaging Initiative (ADNI), the Australian Imaging, Biomarker, and Lifestyle Flagship Study of Ageing (AIBL), and the Open Access Series of Imaging Studies (OASIS). Our MIMD-3DVT, utilizing single or multiple ROIs, achieved an accuracy of 97.14%, outperforming the state-of-the-art methods in distinguishing between Normal Cognition and Alzheimer's Disease.
