Defining reference models for population variation, and the ability to study individual deviations is essential for understanding inter-individual variability and its relation to the onset and progression of medical conditions. In this work, we assembled a reference cohort of neuroimaging data from 82 sites (N=58,836; ages 2-100) and used normative modeling to characterize lifespan trajectories of cortical thickness and subcortical volume. Models are validated against a manually quality checked subset (N=24,354) and we provide an interface for transferring to new data sources. We showcase the clinical value by applying the models to a transdiagnostic psychiatric sample (N=1985), showing they can be used to quantify variability underlying multiple disorders whilst also refining case-control inferences. These models will be augmented with additional samples and imaging modalities as they become available. This provides a common reference platform to bind results from different studies and ultimately paves the way for personalized clinical decision-making.
定义人群变异的参考模型,以及研究个体偏差的能力,对于理解个体间的可变性及其与医疗状况的发生和进展的关系至关重要。在这项工作中,我们汇集了来自 82 个地点的神经影像学数据参考队列(N=58836;年龄 2-100 岁),并使用规范建模来描述皮质厚度和皮质下体积的寿命轨迹。我们根据手动质量检查子集(N=24354)对模型进行了验证,并提供了一个将其转移到新数据源的接口。我们通过将模型应用于跨诊断精神科样本(N=1985)来展示其临床价值,表明它们可以用于量化多种疾病的潜在变异性,同时还可以改进病例对照推断。随着更多样本和成像方式的出现,这些模型将得到扩充。这为结合来自不同研究的结果提供了一个通用的参考平台,并最终为个性化临床决策铺平了道路。
