Generative AI framework-based modeling and prediction of longitudinal human brain images offer an efficient mechanism to track neurodegenerative progression, essential for the assessment of diseases like Alzheimer's. Among the existing generative approaches, recent diffusion-based models have emerged as an effective alternative to generate disease progression images. Incorporating multi-modal and non-imaging attributes as conditional information into diffusion frameworks has been shown to improve controllability during such generations. However, existing methods do not explicitly ensure that information from non-imaging conditioning modalities is meaningfully aligned with image features to introduce desirable changes in the generated images, such as modulation of progression-specific regions. Further, more precise control over the generation process can be achieved by introducing progression-relevant structure into the internal representations of the model, lacking in the existing approaches. To address these limitations, we propose a diffusion autoencoder-based framework for disease progression modeling that explicitly enforces alignment between different modalities. The alignment is enforced by introducing an explicit objective function that enables the model to focus on the regions exhibiting progression-related changes. Further, we devise a mechanism to better structure the latent representational space of the diffusion auto-encoding framework. Specifically, we assign separate latent subspaces for integrating progression-related conditions and retaining subject-specific identity information, allowing better-controlled image generation. These results demonstrate that enforcing alignment and better structuring of the latent representational space of diffusion auto-encoding framework leads to more anatomically precise modeling of Alzheimer's disease progression.

在这里,我们提出了DIVE:数据驱动的顶点进化推理。DIVE是一种基于图像的疾病进展模型,具有单顶点分辨率,旨在从短期纵向数据集重建大脑病理学的长期模式。DIVE对在患者群体中具有类似时间动态的皮质表面上的逐顶点生物标志物测量进行聚类,并且同时估计每个聚类中的顶点测量的平均轨迹。DIVE独特地将皮质分割成具有共同进展模式的区域,从而为个体疾病提供新的签名。DIVE进一步估计每个受试者每次访视的疾病分期和进展速度,可能增强临床试验或管理的分层。在模拟数据上,DIVE可以恢复地面实况集群及其底层轨迹,前提是集群之间的平均轨迹有足够的差异。我们证明了DIVE的数据来自两个队列:阿尔茨海默病神经影像学倡议(ADNI)和痴呆症研究中心(DRC),英国,包含患者与后皮质萎缩(PCA)以及典型的阿尔茨海默病(tAD)。DIVE在两个独立的数据集(ADNI和DRC)中发现了tAD受试者的萎缩的相似空间模式,并进一步揭示了不同疾病(tAD vs PCA)和不同类型生物标志物数据的不同病理模式:来自磁共振成像(MRI)的皮质厚度vs来自正电子发射断层扫描(PET)的淀粉样蛋白负荷。最后,DIVE可用于使用任何种类的逐体素或逐顶点测量(包括雅可比压缩图、来自扩散成像的分数各向异性(FA)图或其他PET测量)来估计脑中病理的细粒度空间分布。DIVE源代码可在线获得:https://github.com/m…
