摘要:

临床神经影像学最近见证了数据可用性的爆炸性增长,这使得研究临床队列中的异质性成为人们关注的焦点。规范建模是实现这一目标的一个新兴统计工具。然而,其应用在技术上仍然具有挑战性,这是由于在适当地处理干扰变化方面的困难,例如由于图像采集设备的可变性。在这里,在一个完全概率的框架,我们提出了一个应用程序的层次贝叶斯回归(HBR)多站点规范建模。我们的实验结果证实了HBR的优越性,在获得更准确的规范范围的大型多站点神经影像学数据相比,广泛使用的方法。这提供了以下可能性:i)在大型多站点数据上学习结构和功能大脑测量的规范范围; ii)在本地小数据上重新校准和重用学习的模型;因此,HBR关闭了将规范建模应用为精神障碍诊断和预后的医学工具的技术循环。

英文摘要:

Clinical neuroimaging has recently witnessed explosive growth in data availability which brings studying heterogeneity in clinical cohorts to the spotlight. Normative modeling is an emerging statistical tool for achieving this objective. However, its application remains technically challenging due to difficulties in properly dealing with nuisance variation, for example due to variability in image acquisition devices. Here, in a fully probabilistic framework, we propose an application of hierarchical Bayesian regression (HBR) for multi-site normative modeling. Our experimental results confirm the superiority of HBR in deriving more accurate normative ranges on large multi-site neuroimaging data compared to widely used methods. This provides the possibility i) to learn the normative range of structural and functional brain measures on large multi-site data; ii) to recalibrate and reuse the learned model on local small data; therefore, HBR closes the technical loop for applying normative modeling as a medical tool for the diagnosis and prognosis of mental disorders.
